2025/06/16 - AWS Network Firewall - 6 new8 updated api methods
Changes You can now create firewalls using a Transit Gateway instead of a VPC, resulting in a TGW attachment.
Associates the specified Availability Zones with a transit gateway-attached firewall. For each Availability Zone, Network Firewall creates a firewall endpoint to process traffic. You can specify one or more Availability Zones where you want to deploy the firewall.
After adding Availability Zones, you must update your transit gateway route tables to direct traffic through the new firewall endpoints. Use DescribeFirewall to monitor the status of the new endpoints.

string
An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.
To make an unconditional change to the firewall, omit the token in your update request. Without the token, Network Firewall performs your updates regardless of whether the firewall has changed since you last retrieved it.
To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.
string
The Amazon Resource Name (ARN) of the firewall.
You must specify the ARN or the name, and you can specify both.

Creates an Network Firewall Firewall and accompanying FirewallStatus for a VPC.
The firewall defines the configuration settings for an Network Firewall firewall. The settings that you can define at creation include the firewall policy, the subnets in your VPC to use for the firewall endpoints, and any tags that are attached to the firewall Amazon Web Services resource.
After you create a firewall, you can provide additional settings, like the logging configuration.
To update the settings for a firewall, you use the operations that apply to the settings themselves, for example UpdateLoggingConfiguration, AssociateSubnets, and UpdateFirewallDeleteProtection.
To manage a firewall's tags, use the standard Amazon Web Services resource tagging operations, ListTagsForResource, TagResource, and UntagResource.
To retrieve information about firewalls, use ListFirewalls and DescribeFirewall.
To generate a report on the last 30 days of traffic monitored by a firewall, use StartAnalysisReport.

When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all Availability Zones that have subnets defined for the firewall. This summary indicates whether the configuration changes have been applied everywhere.
This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness. It's based on this setting and the readiness of the firewall endpoints to take traffic.
SyncStates (dict) --
Status for the subnets that you've configured in the firewall. This contains one array element per Availability Zone where you've configured a subnet in the firewall.
These objects provide detailed information for the settings ConfigurationSyncStateSummary and Status.
(string) --
(dict) --
The status of the firewall endpoint and firewall policy configuration for a single VPC subnet. This is part of the FirewallStatus.
For each VPC subnet that you associate with a firewall, Network Firewall does the following:
Instantiates a firewall endpoint in the subnet, ready to take traffic.
Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.
When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.
Attachment (dict) --
The configuration and status for a single firewall subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic.
SubnetId (string) --
The unique identifier of the subnet that you've specified to be used for a firewall endpoint.
EndpointId (string) --
The identifier of the firewall endpoint that Network Firewall has instantiated in the subnet. You use this to identify the firewall endpoint in the VPC route tables, when you redirect the VPC traffic through the endpoint.
Status (string) --
The current status of the firewall endpoint instantiation in the subnet.
When this value is READY, the endpoint is available to handle network traffic. Otherwise, this value reflects its state, for example CREATING or DELETING.
StatusMessage (string) --
If Network Firewall fails to create or delete the firewall endpoint in the subnet, it populates this with the reason for the error or failure and how to resolve it. A FAILED status indicates a non-recoverable state, and a ERROR status indicates an issue that you can fix. Depending on the error, it can take as many as 15 minutes to populate this field. For more information about the causes for failiure or errors and solutions available for this field, see Troubleshooting firewall endpoint failures in the Network Firewall Developer Guide.
Config (dict) --
The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic.
(string) --
(dict) --
Provides configuration status for a single policy or rule group that is used for a firewall endpoint. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of a SyncState for a firewall.
SyncStatus (string) --
Indicates whether this object is in sync with the version indicated in the update token.
UpdateToken (string) --
The current version of the object that is either in sync or pending synchronization.
CapacityUsageSummary (dict) --
Describes the capacity usage of the resources contained in a firewall's reference sets. Network Firewall calculates the capacity usage by taking an aggregated count of all of the resources used by all of the reference sets in a firewall.
CIDRs (dict) --
Describes the capacity usage of the CIDR blocks used by the IP set references in a firewall.
AvailableCIDRCount (integer) --
The number of CIDR blocks available for use by the IP set references in a firewall.

ResolvedCIDRCount (integer) --
Describes the total number of CIDR blocks currently in use by the IP set references in a firewall. To determine how many CIDR blocks are available for you to use in a firewall, you can call AvailableCIDRCount.
TransitGatewayAttachmentSyncState (dict) --
The synchronization state of the transit gateway attachment. This indicates whether the firewall's transit gateway configuration is properly synchronized and operational. Use this to verify that your transit gateway configuration changes have been applied.
AttachmentId (string) --
The unique identifier of the transit gateway attachment.

The descriptive name of the rule group. You can't change the name of a rule group after you create it.
dict
An object that defines the rule group rules.
RuleVariables (dict) --
Settings that are available for use in the rules in the rule group. You can only use these for stateful rule groups.
IPSets (dict) --
A list of IP addresses and address ranges, in CIDR notation.
(string) --
(dict) --
A list of IP addresses and address ranges, in CIDR notation. This is part of a RuleVariables.
Definition (list) -- [REQUIRED]
The list of IP addresses and address ranges, in CIDR notation.
(string) --
PortSets (dict) --
A list of port ranges.
(string) --
(dict) --
A set of port ranges for use in the rules in a rule group.
Definition (list) --
The set of port ranges.

The list of a rule group's reference sets.
IPSetReferences (dict) --
The list of IP set references.
(string) --
(dict) --
Configures one or more IP set references for a Suricata-compatible rule group. This is used in CreateRuleGroup or UpdateRuleGroup. An IP set reference is a rule variable that references resources that you create and manage in another Amazon Web Services service, such as an Amazon VPC prefix list. Network Firewall IP set references enable you to dynamically update the contents of your rules. When you create, update, or delete the resource you are referencing in your rule, Network Firewall automatically updates the rule's content with the changes. For more information about IP set references in Network Firewall, see Using IP set references in the Network Firewall Developer Guide.
Network Firewall currently supports Amazon VPC prefix lists and resource groups in IP set references.
ReferenceArn (string) --
The Amazon Resource Name (ARN) of the resource that you are referencing in your rule group.
RulesSource (dict) -- [REQUIRED]
The stateful rules or stateless rules for the rule group.
RulesString (string) --
Stateful inspection criteria, provided in Suricata compatible rules. Suricata is an open-source threat detection framework that includes a standard rule-based language for network traffic inspection.
These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn't have a separate action setting.
RulesSourceList (dict) --
Stateful inspection criteria for a domain list rule group.
Targets (list) -- [REQUIRED]
The domains that you want to inspect for in your traffic flows. Valid domain specifications are the following:
Explicit names. For example, abc.example.com matches only the domain abc.example.com.
Names that use a domain wildcard, which you indicate with an initial ' .'. For example, .example.com matches example.com and matches all subdomains of example.com, such as abc.example.com and www.example.com.
(string) --
TargetTypes (list) -- [REQUIRED]
The protocols you want to inspect. Specify TLS_SNI for HTTPS. Specify HTTP_HOST for HTTP. You can specify either or both.
(string) --
GeneratedRulesType (string) -- [REQUIRED]
Whether you want to allow or deny access to the domains in your target list.
StatefulRules (list) --
An array of individual stateful rules inspection criteria to be used together in a stateful rule group. Use this option to specify simple Suricata rules with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format.
(dict) --
A single Suricata rules specification, for use in a stateful rule group. Use this option to specify a simple Suricata rule with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format.
Action (string) -- [REQUIRED]
Defines what Network Firewall should do with the packets in a traffic flow when the flow matches the stateful rule criteria. For all actions, Network Firewall performs the specified action and discontinues stateful inspection of the traffic flow.
The actions for a stateful rule are defined as follows:
PASS - Permits the packets to go to the intended destination.
DROP - Blocks the packets from going to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration.
ALERT - Sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration. You can use this action to test a rule that you intend to use to drop traffic. You can enable the rule with ALERT action, verify in the logs that the rule is filtering as you want, then change the action to DROP.
REJECT - Drops traffic that matches the conditions of the stateful rule, and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and an RST bit contained in the TCP header flags. REJECT is available only for TCP traffic. This option doesn't support FTP or IMAP protocols.
Header (dict) -- [REQUIRED]
The stateful inspection criteria for this rule, used to inspect traffic flows.

SourcePorts (list) --
The source port to inspect for. You can specify an individual port, for example 1994 and you can specify a port range, for example 1990:1994. To match with any port, specify ANY.
If not specified, this matches with any source port.
This setting is only used for protocols 6 (TCP) and 17 (UDP).
(dict) --
A single port range specification. This is used for source and destination port ranges in the stateless rule MatchAttributes, SourcePorts, and DestinationPorts settings.
FromPort (integer) -- [REQUIRED]

TCPFlags (list) --
The TCP flags and masks to inspect for. If not specified, this matches with any settings. This setting is only used for protocol 6 (TCP).
(dict) --
TCP flags and masks to inspect packets for, used in stateless rules MatchAttributes settings.
Flags (list) -- [REQUIRED]
Used in conjunction with the Masks setting to define the flags that must be set and flags that must not be set in order for the packet to match. This setting can only specify values that are also specified in the Masks setting.
For the flags that are specified in the masks setting, the following must be true for the packet to match:
The ones that are set in this flags setting must be set in the packet.
The ones that are not set in this flags setting must also not be set in the packet.
(string) --
Masks (list) --
The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.
(string) --
Actions (list) -- [REQUIRED]
The actions to take on a packet that matches one of the stateless rule definition's match attributes. You must specify a standard action and you can add custom actions.
For every rule, you must specify exactly one of the following standard actions.
aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.
aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.
aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.
Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction.
To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction, then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”].
(string) --
Priority (integer) -- [REQUIRED]
Indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.
Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.
You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.
CustomActions (list) --
Defines an array of individual custom action definitions that are available for use by the stateless rules in this StatelessRulesAndCustomActions specification. You name each custom action that you define, and then you can use it by name in your StatelessRule RuleDefinition Actions specification.
(dict) --
An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.
You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.
You can use custom actions in the following places:
In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.
In a FirewallPolicy specification, in StatelessCustomActions. The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.
ActionName (string) -- [REQUIRED]
The descriptive name of the custom action. You can't change the name of a custom action after you create it.
ActionDefinition (dict) -- [REQUIRED]
The custom action associated with the action name.
PublishMetricAction (dict) --
Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.
You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.
Dimensions (list) -- [REQUIRED]
(dict) --
The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction. A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.
Network Firewall sets the dimension name to CustomAction and you provide the dimension value.
For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide.
Value (string) -- [REQUIRED]
The value to use in the custom metric dimension.
StatefulRuleOptions (dict) --
Additional options governing how Network Firewall handles stateful rules. The policies where you use your stateful rule group must have stateful rule options settings that are compatible with these settings. Some limitations apply; for more information, see Strict evaluation order in the Network Firewall Developer Guide.
RuleOrder (string) --
Indicates how to manage the order of the rule evaluation for the rule group. DEFAULT_ACTION_ORDER is the default behavior. Stateful rules are provided to the rule engine as Suricata compatible strings, and Suricata evaluates them based on certain settings. For more information, see Evaluation order for stateful rules in the Network Firewall Developer Guide.
string
A string containing stateful rule group rules specifications in Suricata flat format, with one rule per line. Use this to import your existing Suricata compatible rule groups.
You can provide your rule group specification in Suricata flat format through this setting when you create or update your rule group. The call response returns a RuleGroup object that Network Firewall has populated from your string.
string
[REQUIRED]
Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.
string
A description of the rule group.
integer
[REQUIRED]
The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.
You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with DryRun set to TRUE.
Capacity for a stateless rule group
For a stateless rule group, the capacity required is the sum of the capacity requirements of the individual rules that you expect to have in the rule group.
To calculate the capacity requirement of a single rule, multiply the capacity requirement values of each of the rule's match settings:
A match setting with no criteria specified has a value of 1.
A match setting with Any specified has a value of 1.
All other match settings have a value equal to the number of elements provided in the setting. For example, a protocol setting ["UDP"] and a source setting ["10.0.0.0/24"] each have a value of 1. A protocol setting ["UDP","TCP"] has a value of 2. A source setting ["10.0.0.0/24","10.0.0.1/24","10.0.0.2/24"] has a value of 3.
A rule with no criteria specified in any of its match settings has a capacity requirement of 1. A rule with protocol setting ["UDP","TCP"], source setting ["10.0.0.0/24","10.0.0.1/24","10.0.0.2/24"], and a single specification or no specification for each of the other match settings has a capacity requirement of 6.
Capacity for a stateful rule group
For a stateful rule group, the minimum capacity required is the number of individual rules that you expect to have in the rule group.
list
The key:value pairs to associate with the resource.
(dict) --
A key:value pair associated with an Amazon Web Services resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each Amazon Web Services resource.
Key (string) -- [REQUIRED]
The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.
Value (string) -- [REQUIRED]
The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.
boolean
Indicates whether you want Network Firewall to just check the validity of the request, rather than run the request.
If set to TRUE, Network Firewall checks whether the request can run successfully, but doesn't actually make the requested changes. The call returns the value that the request would return if you ran it with dry run set to FALSE, but doesn't make additions or changes to your resources. This option allows you to make sure that you have the required permissions to run the request and that your request parameters are valid.
If set to FALSE, Network Firewall makes the requested changes to your resources.
dict
A complex type that contains settings for encryption of your rule group resources.
KeyId (string) --
The ID of the Amazon Web Services Key Management Service (KMS) customer managed key. You can use any of the key identifiers that KMS supports, unless you're using a key that's managed by another account. If you're using a key managed by another account, then specify the key ARN. For more information, see Key ID in the Amazon Web Services KMS Developer Guide.
Type (string) -- [REQUIRED]
The type of Amazon Web Services KMS key to use for encryption of your Network Firewall resources.
dict

UpdateToken (string) --
A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.
To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.

(dict) --
The analysis result for Network Firewall's stateless rule group analyzer. Every time you call CreateRuleGroup, UpdateRuleGroup, or DescribeRuleGroup on a stateless rule group, Network Firewall analyzes the stateless rule groups in your account and identifies the rules that might adversely effect your firewall's functionality. For example, if Network Firewall detects a rule that's routing traffic asymmetrically, which impacts the service's ability to properly process traffic, the service includes the rule in a list of analysis results.
The AnalysisResult data type is not related to traffic analysis reports you generate using StartAnalysisReport. For information on traffic analysis report results, see AnalysisTypeReportResult.
IdentifiedRuleIds (list) --
The priority number of the stateless rules identified in the analysis.
(string) --
IdentifiedType (string) --
The types of rule configurations that Network Firewall analyzes your rule groups for. Network Firewall analyzes stateless rule groups for the following types of rule configurations:
STATELESS_RULE_FORWARDING_ASYMMETRICALLY Cause: One or more stateless rules with the action pass or forward are forwarding traffic asymmetrically. Specifically, the rule's set of source IP addresses or their associated port numbers, don't match the set of destination IP addresses or their associated port numbers. To mitigate: Make sure that there's an existing return path. For example, if the rule allows traffic from source 10.1.0.0/24 to destination 20.1.0.0/24, you should allow return traffic from source 20.1.0.0/24 to destination 10.1.0.0/24.
STATELESS_RULE_CONTAINS_TCP_FLAGS Cause: At least one stateless rule with the action pass or forward contains TCP flags that are inconsistent in the forward and return directions. To mitigate: Prevent asymmetric routing issues caused by TCP flags by following these actions:
Remove unnecessary TCP flag inspections from the rules.
If you need to inspect TCP flags, check that the rules correctly account for changes in TCP flags throughout the TCP connection cycle, for example SYN and ACK flags used in a 3-way TCP handshake.
AnalysisDetail (string) --
Provides analysis details for the identified rule.

Deletes the specified Firewall and its FirewallStatus. This operation requires the firewall's DeleteProtection flag to be FALSE. You can't revert this operation.
You can check whether a firewall is in use by reviewing the route tables for the Availability Zones where you have firewall subnet mappings. Retrieve the subnet mappings by calling DescribeFirewall. You define and update the route tables through Amazon VPC. As needed, update the route tables for the zones to remove the firewall endpoints. When the route tables no longer use the firewall endpoints, you can remove the firewall safely.
To delete a firewall, remove the delete protection if you need to using UpdateFirewallDeleteProtection, then delete the firewall by calling DeleteFirewall.

Response Structure
(dict) --
Firewall (dict) --
A firewall defines the behavior of a firewall, the main VPC where the firewall is used, the Availability Zones where the firewall can be used, and one subnet to use for a firewall endpoint within each of the Availability Zones. The Availability Zones are defined implicitly in the subnet specifications.
In addition to the firewall endpoints that you define in this Firewall specification, you can create firewall endpoints in VpcEndpointAssociation resources for any VPC, in any Availability Zone where the firewall is already in use.
The status of the firewall, for example whether it's ready to filter network traffic, is provided in the corresponding FirewallStatus. You can retrieve both the firewall and firewall status by calling DescribeFirewall.
FirewallName (string) --
The descriptive name of the firewall. You can't change the name of a firewall after you create it.
FirewallArn (string) --
The Amazon Resource Name (ARN) of the firewall.
FirewallPolicyArn (string) --
The Amazon Resource Name (ARN) of the firewall policy.
The relationship of firewall to firewall policy is many to one. Each firewall requires one firewall policy association, and you can use the same firewall policy for multiple firewalls.
VpcId (string) --
The unique identifier of the VPC where the firewall is in use.
SubnetMappings (list) --
The primary public subnets that Network Firewall is using for the firewall. Network Firewall creates a firewall endpoint in each subnet. Create a subnet mapping for each Availability Zone where you want to use the firewall.
These subnets are all defined for a single, primary VPC, and each must belong to a different Availability Zone. Each of these subnets establishes the availability of the firewall in its Availability Zone.
In addition to these subnets, you can define other endpoints for the firewall in VpcEndpointAssociation resources. You can define these additional endpoints for any VPC, and for any of the Availability Zones where the firewall resource already has a subnet mapping. VPC endpoint associations give you the ability to protect multiple VPCs using a single firewall, and to define multiple firewall endpoints for a VPC in a single Availability Zone.
(dict) --
The ID for a subnet that's used in an association with a firewall. This is used in CreateFirewall, AssociateSubnets, and CreateVpcEndpointAssociation. Network Firewall creates an instance of the associated firewall in each subnet that you specify, to filter traffic in the subnet's Availability Zone.
SubnetId (string) --
The unique identifier for the subnet.
IPAddressType (string) --
The subnet's IP address type. You can't change the IP address type after you create the subnet.
DeleteProtection (boolean) --
A flag indicating whether it is possible to delete the firewall. A setting of TRUE indicates that the firewall is protected against deletion. Use this setting to protect against accidentally deleting a firewall that is in use. When you create a firewall, the operation initializes this flag to TRUE.
SubnetChangeProtection (boolean) --
A setting indicating whether the firewall is protected against changes to the subnet associations. Use this setting to protect against accidentally modifying the subnet associations for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE.
FirewallPolicyChangeProtection (boolean) --
A setting indicating whether the firewall is protected against a change to the firewall policy association. Use this setting to protect against accidentally modifying the firewall policy for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE.
Description (string) --
A description of the firewall.
FirewallId (string) --
The unique identifier for the firewall.
Tags (list) --
(dict) --
A key:value pair associated with an Amazon Web Services resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each Amazon Web Services resource.
Key (string) --
The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.
Value (string) --
The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.
EncryptionConfiguration (dict) --
A complex type that contains the Amazon Web Services KMS encryption configuration settings for your firewall.
KeyId (string) --
The ID of the Amazon Web Services Key Management Service (KMS) customer managed key. You can use any of the key identifiers that KMS supports, unless you're using a key that's managed by another account. If you're using a key managed by another account, then specify the key ARN. For more information, see Key ID in the Amazon Web Services KMS Developer Guide.
Type (string) --
The type of Amazon Web Services KMS key to use for encryption of your Network Firewall resources.
NumberOfAssociations (integer) --
The number of VpcEndpointAssociation resources that use this firewall.
EnabledAnalysisTypes (list) --
An optional setting indicating the specific traffic analysis types to enable on the firewall.
(string) --
TransitGatewayId (string) --
The unique identifier of the transit gateway associated with this firewall. This field is only present for transit gateway-attached firewalls.
TransitGatewayOwnerAccountId (string) --
The Amazon Web Services account ID that owns the transit gateway. This may be different from the firewall owner's account ID when using a shared transit gateway.
AvailabilityZoneMappings (list) --
The Availability Zones where the firewall endpoints are created for a transit gateway-attached firewall. Each mapping specifies an Availability Zone where the firewall processes traffic.
(dict) --
Defines the mapping between an Availability Zone and a firewall endpoint for a transit gateway-attached firewall. Each mapping represents where the firewall can process traffic. You use these mappings when calling CreateFirewall, AssociateAvailabilityZones, and DisassociateAvailabilityZones.
To retrieve the current Availability Zone mappings for a firewall, use DescribeFirewall.
AvailabilityZone (string) --
The ID of the Availability Zone where the firewall endpoint is located. For example, us-east-2a. The Availability Zone must be in the same Region as the transit gateway.
AvailabilityZoneChangeProtection (boolean) --
A setting indicating whether the firewall is protected against changes to its Availability Zone configuration. When set to TRUE, you must first disable this protection before adding or removing Availability Zones.
FirewallStatus (dict) --
Detailed information about the current status of a Firewall. You can retrieve this for a firewall by calling DescribeFirewall and providing the firewall name and ARN.
The firewall status indicates a combined status. It indicates whether all subnets are up-to-date with the latest firewall configurations, which is based on the sync states config values, and also whether all subnets have their endpoints fully enabled, based on their sync states attachment values.
Status (string) --
The readiness of the configured firewall to handle network traffic across all of the Availability Zones where you have it configured. This setting is READY only when the ConfigurationSyncStateSummary value is IN_SYNC and the Attachment Status values for all of the configured subnets are READY.
ConfigurationSyncStateSummary (string) --
The configuration sync state for the firewall. This summarizes the Config settings in the SyncStates for this firewall status object.
When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all Availability Zones that have subnets defined for the firewall. This summary indicates whether the configuration changes have been applied everywhere.
This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness. It's based on this setting and the readiness of the firewall endpoints to take traffic.
SyncStates (dict) --
Status for the subnets that you've configured in the firewall. This contains one array element per Availability Zone where you've configured a subnet in the firewall.
These objects provide detailed information for the settings ConfigurationSyncStateSummary and Status.
(string) --
(dict) --
The status of the firewall endpoint and firewall policy configuration for a single VPC subnet. This is part of the FirewallStatus.
For each VPC subnet that you associate with a firewall, Network Firewall does the following:
Instantiates a firewall endpoint in the subnet, ready to take traffic.
Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.
When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.
Attachment (dict) --
The configuration and status for a single firewall subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic.
SubnetId (string) --
The unique identifier of the subnet that you've specified to be used for a firewall endpoint.
EndpointId (string) --
The identifier of the firewall endpoint that Network Firewall has instantiated in the subnet. You use this to identify the firewall endpoint in the VPC route tables, when you redirect the VPC traffic through the endpoint.
Status (string) --
The current status of the firewall endpoint instantiation in the subnet.
When this value is READY, the endpoint is available to handle network traffic. Otherwise, this value reflects its state, for example CREATING or DELETING.
StatusMessage (string) --
If Network Firewall fails to create or delete the firewall endpoint in the subnet, it populates this with the reason for the error or failure and how to resolve it. A FAILED status indicates a non-recoverable state, and a ERROR status indicates an issue that you can fix. Depending on the error, it can take as many as 15 minutes to populate this field. For more information about the causes for failiure or errors and solutions available for this field, see Troubleshooting firewall endpoint failures in the Network Firewall Developer Guide.
Config (dict) --
The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic.
(string) --
(dict) --
Provides configuration status for a single policy or rule group that is used for a firewall endpoint. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of a SyncState for a firewall.
SyncStatus (string) --
Indicates whether this object is in sync with the version indicated in the update token.
UpdateToken (string) --
The current version of the object that is either in sync or pending synchronization.
CapacityUsageSummary (dict) --
Describes the capacity usage of the resources contained in a firewall's reference sets. Network Firewall calculates the capacity usage by taking an aggregated count of all of the resources used by all of the reference sets in a firewall.
CIDRs (dict) --
Describes the capacity usage of the CIDR blocks used by the IP set references in a firewall.
AvailableCIDRCount (integer) --
The number of CIDR blocks available for use by the IP set references in a firewall.

(string) --
(dict) --
General information about the IP set.
ResolvedCIDRCount (integer) --
Describes the total number of CIDR blocks currently in use by the IP set references in a firewall. To determine how many CIDR blocks are available for you to use in a firewall, you can call AvailableCIDRCount.
TransitGatewayAttachmentSyncState (dict) --
The synchronization state of the transit gateway attachment. This indicates whether the firewall's transit gateway configuration is properly synchronized and operational. Use this to verify that your transit gateway configuration changes have been applied.
AttachmentId (string) --
The unique identifier of the transit gateway attachment.

Response Structure
(dict) --
UpdateToken (string) --
An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.
To make an unconditional change to the firewall, omit the token in your update request. Without the token, Network Firewall performs your updates regardless of whether the firewall has changed since you last retrieved it.
To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.
Firewall (dict) --
The configuration settings for the firewall. These settings include the firewall policy and the subnets in your VPC to use for the firewall endpoints.
FirewallName (string) --
The descriptive name of the firewall. You can't change the name of a firewall after you create it.
FirewallArn (string) --
The Amazon Resource Name (ARN) of the firewall.
FirewallPolicyArn (string) --
The Amazon Resource Name (ARN) of the firewall policy.
The relationship of firewall to firewall policy is many to one. Each firewall requires one firewall policy association, and you can use the same firewall policy for multiple firewalls.
VpcId (string) --
The unique identifier of the VPC where the firewall is in use.
SubnetMappings (list) --
The primary public subnets that Network Firewall is using for the firewall. Network Firewall creates a firewall endpoint in each subnet. Create a subnet mapping for each Availability Zone where you want to use the firewall.
These subnets are all defined for a single, primary VPC, and each must belong to a different Availability Zone. Each of these subnets establishes the availability of the firewall in its Availability Zone.
In addition to these subnets, you can define other endpoints for the firewall in VpcEndpointAssociation resources. You can define these additional endpoints for any VPC, and for any of the Availability Zones where the firewall resource already has a subnet mapping. VPC endpoint associations give you the ability to protect multiple VPCs using a single firewall, and to define multiple firewall endpoints for a VPC in a single Availability Zone.
(dict) --
The ID for a subnet that's used in an association with a firewall. This is used in CreateFirewall, AssociateSubnets, and CreateVpcEndpointAssociation. Network Firewall creates an instance of the associated firewall in each subnet that you specify, to filter traffic in the subnet's Availability Zone.
SubnetId (string) --
The unique identifier for the subnet.
IPAddressType (string) --
The subnet's IP address type. You can't change the IP address type after you create the subnet.
DeleteProtection (boolean) --
A flag indicating whether it is possible to delete the firewall. A setting of TRUE indicates that the firewall is protected against deletion. Use this setting to protect against accidentally deleting a firewall that is in use. When you create a firewall, the operation initializes this flag to TRUE.
SubnetChangeProtection (boolean) --
A setting indicating whether the firewall is protected against changes to the subnet associations. Use this setting to protect against accidentally modifying the subnet associations for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE.
FirewallPolicyChangeProtection (boolean) --
A setting indicating whether the firewall is protected against a change to the firewall policy association. Use this setting to protect against accidentally modifying the firewall policy for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE.
Description (string) --
A description of the firewall.
FirewallId (string) --
The unique identifier for the firewall.
Tags (list) --
(dict) --
A key:value pair associated with an Amazon Web Services resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each Amazon Web Services resource.
Key (string) --
The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.
Value (string) --
The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.
EncryptionConfiguration (dict) --
A complex type that contains the Amazon Web Services KMS encryption configuration settings for your firewall.
KeyId (string) --
The ID of the Amazon Web Services Key Management Service (KMS) customer managed key. You can use any of the key identifiers that KMS supports, unless you're using a key that's managed by another account. If you're using a key managed by another account, then specify the key ARN. For more information, see Key ID in the Amazon Web Services KMS Developer Guide.
Type (string) --
The type of Amazon Web Services KMS key to use for encryption of your Network Firewall resources.
NumberOfAssociations (integer) --
The number of VpcEndpointAssociation resources that use this firewall.

The Amazon Web Services account ID that owns the transit gateway. This may be different from the firewall owner's account ID when using a shared transit gateway.
AvailabilityZoneMappings (list) --
The Availability Zones where the firewall endpoints are created for a transit gateway-attached firewall. Each mapping specifies an Availability Zone where the firewall processes traffic.
(dict) --
Defines the mapping between an Availability Zone and a firewall endpoint for a transit gateway-attached firewall. Each mapping represents where the firewall can process traffic. You use these mappings when calling CreateFirewall, AssociateAvailabilityZones, and DisassociateAvailabilityZones.
To retrieve the current Availability Zone mappings for a firewall, use DescribeFirewall.
AvailabilityZone (string) --
The ID of the Availability Zone where the firewall endpoint is located. For example, us-east-2a. The Availability Zone must be in the same Region as the transit gateway.
AvailabilityZoneChangeProtection (boolean) --
A setting indicating whether the firewall is protected against changes to its Availability Zone configuration. When set to TRUE, you must first disable this protection before adding or removing Availability Zones.
FirewallStatus (dict) --
Detailed information about the current status of a Firewall. You can retrieve this for a firewall by calling DescribeFirewall and providing the firewall name and ARN.
The firewall status indicates a combined status. It indicates whether all subnets are up-to-date with the latest firewall configurations, which is based on the sync states config values, and also whether all subnets have their endpoints fully enabled, based on their sync states attachment values.
Status (string) --
The readiness of the configured firewall to handle network traffic across all of the Availability Zones where you have it configured. This setting is READY only when the ConfigurationSyncStateSummary value is IN_SYNC and the Attachment Status values for all of the configured subnets are READY.
ConfigurationSyncStateSummary (string) --
The configuration sync state for the firewall. This summarizes the Config settings in the SyncStates for this firewall status object.
When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all Availability Zones that have subnets defined for the firewall. This summary indicates whether the configuration changes have been applied everywhere.
This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness. It's based on this setting and the readiness of the firewall endpoints to take traffic.
SyncStates (dict) --
Status for the subnets that you've configured in the firewall. This contains one array element per Availability Zone where you've configured a subnet in the firewall.
These objects provide detailed information for the settings ConfigurationSyncStateSummary and Status.
(string) --
(dict) --
The status of the firewall endpoint and firewall policy configuration for a single VPC subnet. This is part of the FirewallStatus.
For each VPC subnet that you associate with a firewall, Network Firewall does the following:
Instantiates a firewall endpoint in the subnet, ready to take traffic.
Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.
When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.
Attachment (dict) --
The configuration and status for a single firewall subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic.
SubnetId (string) --
The unique identifier of the subnet that you've specified to be used for a firewall endpoint.
EndpointId (string) --
The identifier of the firewall endpoint that Network Firewall has instantiated in the subnet. You use this to identify the firewall endpoint in the VPC route tables, when you redirect the VPC traffic through the endpoint.
Status (string) --
The current status of the firewall endpoint instantiation in the subnet.
When this value is READY, the endpoint is available to handle network traffic. Otherwise, this value reflects its state, for example CREATING or DELETING.
StatusMessage (string) --
If Network Firewall fails to create or delete the firewall endpoint in the subnet, it populates this with the reason for the error or failure and how to resolve it. A FAILED status indicates a non-recoverable state, and a ERROR status indicates an issue that you can fix. Depending on the error, it can take as many as 15 minutes to populate this field. For more information about the causes for failiure or errors and solutions available for this field, see Troubleshooting firewall endpoint failures in the Network Firewall Developer Guide.
Config (dict) --
The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic.
(string) --
(dict) --
Provides configuration status for a single policy or rule group that is used for a firewall endpoint. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of a SyncState for a firewall.

Response Structure
(dict) --
UpdateToken (string) --
A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.
To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.
RuleGroup (dict) --
The object that defines the rules in a rule group. This, along with RuleGroupResponse, define the rule group. You can retrieve all objects for a rule group by calling DescribeRuleGroup.
Network Firewall uses a rule group to inspect and control network traffic. You define stateless rule groups to inspect individual packets and you define stateful rule groups to inspect packets in the context of their traffic flow.
To use a rule group, you include it by reference in an Network Firewall firewall policy, then you use the policy in a firewall. You can reference a rule group from more than one firewall policy, and you can use a firewall policy in more than one firewall.
RuleVariables (dict) --
Settings that are available for use in the rules in the rule group. You can only use these for stateful rule groups.
IPSets (dict) --
A list of IP addresses and address ranges, in CIDR notation.

(string) --
(dict) --
Configures one or more IP set references for a Suricata-compatible rule group. This is used in CreateRuleGroup or UpdateRuleGroup. An IP set reference is a rule variable that references resources that you create and manage in another Amazon Web Services service, such as an Amazon VPC prefix list. Network Firewall IP set references enable you to dynamically update the contents of your rules. When you create, update, or delete the resource you are referencing in your rule, Network Firewall automatically updates the rule's content with the changes. For more information about IP set references in Network Firewall, see Using IP set references in the Network Firewall Developer Guide.
Network Firewall currently supports Amazon VPC prefix lists and resource groups in IP set references.
ReferenceArn (string) --
The Amazon Resource Name (ARN) of the resource that you are referencing in your rule group.
RulesSource (dict) --
The stateful rules or stateless rules for the rule group.
RulesString (string) --
Stateful inspection criteria, provided in Suricata compatible rules. Suricata is an open-source threat detection framework that includes a standard rule-based language for network traffic inspection.
These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn't have a separate action setting.
RulesSourceList (dict) --
Stateful inspection criteria for a domain list rule group.
Targets (list) --
The domains that you want to inspect for in your traffic flows. Valid domain specifications are the following:
Explicit names. For example, abc.example.com matches only the domain abc.example.com.
Names that use a domain wildcard, which you indicate with an initial ' .'. For example, .example.com matches example.com and matches all subdomains of example.com, such as abc.example.com and www.example.com.
(string) --
TargetTypes (list) --
The protocols you want to inspect. Specify TLS_SNI for HTTPS. Specify HTTP_HOST for HTTP. You can specify either or both.
(string) --
GeneratedRulesType (string) --
Whether you want to allow or deny access to the domains in your target list.
StatefulRules (list) --
An array of individual stateful rules inspection criteria to be used together in a stateful rule group. Use this option to specify simple Suricata rules with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format.
(dict) --
A single Suricata rules specification, for use in a stateful rule group. Use this option to specify a simple Suricata rule with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format.
Action (string) --
Defines what Network Firewall should do with the packets in a traffic flow when the flow matches the stateful rule criteria. For all actions, Network Firewall performs the specified action and discontinues stateful inspection of the traffic flow.
The actions for a stateful rule are defined as follows:
PASS - Permits the packets to go to the intended destination.
DROP - Blocks the packets from going to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration.
ALERT - Sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration. You can use this action to test a rule that you intend to use to drop traffic. You can enable the rule with ALERT action, verify in the logs that the rule is filtering as you want, then change the action to DROP.
REJECT - Drops traffic that matches the conditions of the stateful rule, and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and an RST bit contained in the TCP header flags. REJECT is available only for TCP traffic. This option doesn't support FTP or IMAP protocols.
Header (dict) --
The stateful inspection criteria for this rule, used to inspect traffic flows.
Protocol (string) --
The protocol to inspect for. To specify all, you can use IP, because all traffic on Amazon Web Services and on the internet is IP.
Source (string) --
The source IP address or address range to inspect for, in CIDR notation. To match with any address, specify ANY.
Specify an IP address or a block of IP addresses in Classless Inter-Domain Routing (CIDR) notation. Network Firewall supports all address ranges for IPv4 and IPv6.

SourcePorts (list) --
The source port to inspect for. You can specify an individual port, for example 1994 and you can specify a port range, for example 1990:1994. To match with any port, specify ANY.
If not specified, this matches with any source port.
This setting is only used for protocols 6 (TCP) and 17 (UDP).
(dict) --
A single port range specification. This is used for source and destination port ranges in the stateless rule MatchAttributes, SourcePorts, and DestinationPorts settings.
FromPort (integer) --

The TCP flags and masks to inspect for. If not specified, this matches with any settings. This setting is only used for protocol 6 (TCP).
(dict) --
TCP flags and masks to inspect packets for, used in stateless rules MatchAttributes settings.
Flags (list) --
Used in conjunction with the Masks setting to define the flags that must be set and flags that must not be set in order for the packet to match. This setting can only specify values that are also specified in the Masks setting.
For the flags that are specified in the masks setting, the following must be true for the packet to match:
The ones that are set in this flags setting must be set in the packet.
The ones that are not set in this flags setting must also not be set in the packet.
(string) --
Masks (list) --
The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.
(string) --
Actions (list) --
The actions to take on a packet that matches one of the stateless rule definition's match attributes. You must specify a standard action and you can add custom actions.
For every rule, you must specify exactly one of the following standard actions.
aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.
aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.
aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.
Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction.
To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction, then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”].
(string) --
Priority (integer) --
Indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.
Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.
You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.
CustomActions (list) --
Defines an array of individual custom action definitions that are available for use by the stateless rules in this StatelessRulesAndCustomActions specification. You name each custom action that you define, and then you can use it by name in your StatelessRule RuleDefinition Actions specification.
(dict) --
An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.
You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.
You can use custom actions in the following places:
In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.
In a FirewallPolicy specification, in StatelessCustomActions. The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.
ActionName (string) --
The descriptive name of the custom action. You can't change the name of a custom action after you create it.
ActionDefinition (dict) --
The custom action associated with the action name.
PublishMetricAction (dict) --
Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.
You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.
Dimensions (list) --
(dict) --
The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction. A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.
Network Firewall sets the dimension name to CustomAction and you provide the dimension value.
For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide.
Value (string) --
The value to use in the custom metric dimension.
StatefulRuleOptions (dict) --
Additional options governing how Network Firewall handles stateful rules. The policies where you use your stateful rule group must have stateful rule options settings that are compatible with these settings. Some limitations apply; for more information, see Strict evaluation order in the Network Firewall Developer Guide.
RuleOrder (string) --
Indicates how to manage the order of the rule evaluation for the rule group. DEFAULT_ACTION_ORDER is the default behavior. Stateful rules are provided to the rule engine as Suricata compatible strings, and Suricata evaluates them based on certain settings. For more information, see Evaluation order for stateful rules in the Network Firewall Developer Guide.
RuleGroupResponse (dict) --
The high-level properties of a rule group. This, along with the RuleGroup, define the rule group. You can retrieve all objects for a rule group by calling DescribeRuleGroup.

Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.
Capacity (integer) --
The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.
You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with DryRun set to TRUE.
RuleGroupStatus (string) --
Detailed information about the current status of a rule group.
Tags (list) --
The key:value pairs to associate with the resource.
(dict) --
A key:value pair associated with an Amazon Web Services resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each Amazon Web Services resource.
Key (string) --
The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.
Value (string) --

You can use any of the key identifiers that KMS supports, unless you're using a key that's managed by another account. If you're using a key managed by another account, then specify the key ARN. For more information, see Key ID in the Amazon Web Services KMS Developer Guide.
Type (string) --
The type of Amazon Web Services KMS key to use for encryption of your Network Firewall resources.
SourceMetadata (dict) --
A complex type that contains metadata about the rule group that your own rule group is copied from. You can use the metadata to track the version updates made to the originating rule group.
SourceArn (string) --
The Amazon Resource Name (ARN) of the rule group that your own rule group is copied from.
SourceUpdateToken (string) --
The update token of the Amazon Web Services managed rule group that your own rule group is copied from. To determine the update token for the managed rule group, call DescribeRuleGroup.
SnsTopic (string) --
The Amazon Resource Name (ARN) of the Amazon Simple Notification Service SNS topic that's used to record changes to the managed rule group. You can subscribe to the SNS topic to receive notifications when the managed rule group is modified, such as for new versions and for version expiration. For more information, see the Amazon Simple Notification Service Developer Guide..
LastModifiedTime (datetime) --
The last time that the rule group was changed.
AnalysisResults (list) --
The list of analysis results for AnalyzeRuleGroup. If you set AnalyzeRuleGroup to TRUE in CreateRuleGroup, UpdateRuleGroup, or DescribeRuleGroup, Network Firewall analyzes the rule group and identifies the rules that might adversely effect your firewall's functionality. For example, if Network Firewall detects a rule that's routing traffic asymmetrically, which impacts the service's ability to properly process traffic, the service includes the rule in the list of analysis results.
(dict) --
The analysis result for Network Firewall's stateless rule group analyzer. Every time you call CreateRuleGroup, UpdateRuleGroup, or DescribeRuleGroup on a stateless rule group, Network Firewall analyzes the stateless rule groups in your account and identifies the rules that might adversely effect your firewall's functionality. For example, if Network Firewall detects a rule that's routing traffic asymmetrically, which impacts the service's ability to properly process traffic, the service includes the rule in a list of analysis results.
The AnalysisResult data type is not related to traffic analysis reports you generate using StartAnalysisReport. For information on traffic analysis report results, see AnalysisTypeReportResult.
IdentifiedRuleIds (list) --
The priority number of the stateless rules identified in the analysis.
(string) --
IdentifiedType (string) --
The types of rule configurations that Network Firewall analyzes your rule groups for. Network Firewall analyzes stateless rule groups for the following types of rule configurations:
STATELESS_RULE_FORWARDING_ASYMMETRICALLY Cause: One or more stateless rules with the action pass or forward are forwarding traffic asymmetrically. Specifically, the rule's set of source IP addresses or their associated port numbers, don't match the set of destination IP addresses or their associated port numbers. To mitigate: Make sure that there's an existing return path. For example, if the rule allows traffic from source 10.1.0.0/24 to destination 20.1.0.0/24, you should allow return traffic from source 20.1.0.0/24 to destination 10.1.0.0/24.
STATELESS_RULE_CONTAINS_TCP_FLAGS Cause: At least one stateless rule with the action pass or forward contains TCP flags that are inconsistent in the forward and return directions. To mitigate: Prevent asymmetric routing issues caused by TCP flags by following these actions:
Remove unnecessary TCP flag inspections from the rules.
If you need to inspect TCP flags, check that the rules correctly account for changes in TCP flags throughout the TCP connection cycle, for example SYN and ACK flags used in a 3-way TCP handshake.
AnalysisDetail (string) --
Provides analysis details for the identified rule.
{'Firewalls': {'TransitGatewayAttachmentId': 'string'}}

string
[REQUIRED]
A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.
To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.
string
The Amazon Resource Name (ARN) of the rule group.
You must specify the ARN or the name, and you can specify both.
string
The descriptive name of the rule group. You can't change the name of a rule group after you create it.
You must specify the ARN or the name, and you can specify both.
dict
An object that defines the rule group rules.

(string) --
(dict) --
Configures one or more IP set references for a Suricata-compatible rule group. This is used in CreateRuleGroup or UpdateRuleGroup. An IP set reference is a rule variable that references resources that you create and manage in another Amazon Web Services service, such as an Amazon VPC prefix list. Network Firewall IP set references enable you to dynamically update the contents of your rules. When you create, update, or delete the resource you are referencing in your rule, Network Firewall automatically updates the rule's content with the changes. For more information about IP set references in Network Firewall, see Using IP set references in the Network Firewall Developer Guide.
Network Firewall currently supports Amazon VPC prefix lists and resource groups in IP set references.
ReferenceArn (string) --
The Amazon Resource Name (ARN) of the resource that you are referencing in your rule group.
RulesSource (dict) -- [REQUIRED]
The stateful rules or stateless rules for the rule group.
RulesString (string) --
Stateful inspection criteria, provided in Suricata compatible rules. Suricata is an open-source threat detection framework that includes a standard rule-based language for network traffic inspection.
These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn't have a separate action setting.
RulesSourceList (dict) --
Stateful inspection criteria for a domain list rule group.
Targets (list) -- [REQUIRED]
The domains that you want to inspect for in your traffic flows. Valid domain specifications are the following:
Explicit names. For example, abc.example.com matches only the domain abc.example.com.
Names that use a domain wildcard, which you indicate with an initial ' .'. For example, .example.com matches example.com and matches all subdomains of example.com, such as abc.example.com and www.example.com.

GeneratedRulesType (string) -- [REQUIRED]
Whether you want to allow or deny access to the domains in your target list.
StatefulRules (list) --
An array of individual stateful rules inspection criteria to be used together in a stateful rule group. Use this option to specify simple Suricata rules with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format.
(dict) --
A single Suricata rules specification, for use in a stateful rule group. Use this option to specify a simple Suricata rule with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format.
Action (string) -- [REQUIRED]
Defines what Network Firewall should do with the packets in a traffic flow when the flow matches the stateful rule criteria. For all actions, Network Firewall performs the specified action and discontinues stateful inspection of the traffic flow.
The actions for a stateful rule are defined as follows:
PASS - Permits the packets to go to the intended destination.
DROP - Blocks the packets from going to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration.
ALERT - Sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration. You can use this action to test a rule that you intend to use to drop traffic. You can enable the rule with ALERT action, verify in the logs that the rule is filtering as you want, then change the action to DROP.
REJECT - Drops traffic that matches the conditions of the stateful rule, and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and an RST bit contained in the TCP header flags. REJECT is available only for TCP traffic. This option doesn't support FTP or IMAP protocols.
Header (dict) -- [REQUIRED]
The stateful inspection criteria for this rule, used to inspect traffic flows.
Protocol (string) -- [REQUIRED]
The protocol to inspect for. To specify all, you can use IP, because all traffic on Amazon Web Services and on the internet is IP.
Source (string) -- [REQUIRED]
The source IP address or address range to inspect for, in CIDR notation. To match with any address, specify ANY.
Specify an IP address or a block of IP addresses in Classless Inter-Domain Routing (CIDR) notation. Network Firewall supports all address ranges for IPv4 and IPv6.

SourcePort (string) -- [REQUIRED]
The source port to inspect for. You can specify an individual port, for example 1994 and you can specify a port range, for example 1990:1994. To match with any port, specify ANY.
Direction (string) -- [REQUIRED]
The direction of traffic flow to inspect. If set to ANY, the inspection matches bidirectional traffic, both from the source to the destination and from the destination to the source. If set to FORWARD, the inspection only matches traffic going from the source to the destination.
Destination (string) -- [REQUIRED]
The destination IP address or address range to inspect for, in CIDR notation. To match with any address, specify ANY.
Specify an IP address or a block of IP addresses in Classless Inter-Domain Routing (CIDR) notation. Network Firewall supports all address ranges for IPv4 and IPv6.
Examples:
To configure Network Firewall to inspect for the IP address 192.0.2.44, specify 192.0.2.44/32.

Used in conjunction with the Masks setting to define the flags that must be set and flags that must not be set in order for the packet to match. This setting can only specify values that are also specified in the Masks setting.
For the flags that are specified in the masks setting, the following must be true for the packet to match:
The ones that are set in this flags setting must be set in the packet.
The ones that are not set in this flags setting must also not be set in the packet.
(string) --
Masks (list) --
The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.
(string) --
Actions (list) -- [REQUIRED]
The actions to take on a packet that matches one of the stateless rule definition's match attributes. You must specify a standard action and you can add custom actions.
For every rule, you must specify exactly one of the following standard actions.
aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.
aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.
aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.
Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction.
To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction, then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”].
(string) --
Priority (integer) -- [REQUIRED]
Indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.
Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.
You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.
CustomActions (list) --
Defines an array of individual custom action definitions that are available for use by the stateless rules in this StatelessRulesAndCustomActions specification. You name each custom action that you define, and then you can use it by name in your StatelessRule RuleDefinition Actions specification.
(dict) --
An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.
You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.
You can use custom actions in the following places:
In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.
In a FirewallPolicy specification, in StatelessCustomActions. The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.
ActionName (string) -- [REQUIRED]
The descriptive name of the custom action. You can't change the name of a custom action after you create it.
ActionDefinition (dict) -- [REQUIRED]
The custom action associated with the action name.
PublishMetricAction (dict) --
Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.
You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.
Dimensions (list) -- [REQUIRED]
(dict) --
The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction. A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.
Network Firewall sets the dimension name to CustomAction and you provide the dimension value.
For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide.
Value (string) -- [REQUIRED]
The value to use in the custom metric dimension.
StatefulRuleOptions (dict) --
Additional options governing how Network Firewall handles stateful rules. The policies where you use your stateful rule group must have stateful rule options settings that are compatible with these settings. Some limitations apply; for more information, see Strict evaluation order in the Network Firewall Developer Guide.
RuleOrder (string) --
Indicates how to manage the order of the rule evaluation for the rule group. DEFAULT_ACTION_ORDER is the default behavior. Stateful rules are provided to the rule engine as Suricata compatible strings, and Suricata evaluates them based on certain settings. For more information, see Evaluation order for stateful rules in the Network Firewall Developer Guide.
string
A string containing stateful rule group rules specifications in Suricata flat format, with one rule per line. Use this to import your existing Suricata compatible rule groups.
You can provide your rule group specification in Suricata flat format through this setting when you create or update your rule group. The call response returns a RuleGroup object that Network Firewall has populated from your string.
string
Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.
string
A description of the rule group.
boolean
Indicates whether you want Network Firewall to just check the validity of the request, rather than run the request.
If set to TRUE, Network Firewall checks whether the request can run successfully, but doesn't actually make the requested changes. The call returns the value that the request would return if you ran it with dry run set to FALSE, but doesn't make additions or changes to your resources. This option allows you to make sure that you have the required permissions to run the request and that your request parameters are valid.
If set to FALSE, Network Firewall makes the requested changes to your resources.
dict
A complex type that contains settings for encryption of your rule group resources.
KeyId (string) --
The ID of the Amazon Web Services Key Management Service (KMS) customer managed key. You can use any of the key identifiers that KMS supports, unless you're using a key that's managed by another account. If you're using a key managed by another account, then specify the key ARN. For more information, see Key ID in the Amazon Web Services KMS Developer Guide.
Type (string) -- [REQUIRED]
The type of Amazon Web Services KMS key to use for encryption of your Network Firewall resources.
dict
A complex type that contains metadata about the rule group that your own rule group is copied from. You can use the metadata to keep track of updates made to the originating rule group.
SourceArn (string) --
The Amazon Resource Name (ARN) of the rule group that your own rule group is copied from.
SourceUpdateToken (string) --
The update token of the Amazon Web Services managed rule group that your own rule group is copied from. To determine the update token for the managed rule group, call DescribeRuleGroup.
boolean
Indicates whether you want Network Firewall to analyze the stateless rules in the rule group for rule behavior such as asymmetric routing. If set to TRUE, Network Firewall runs the analysis and then updates the rule group for you. To run the stateless rule group analyzer without updating the rule group, set DryRun to TRUE.

Response Structure
(dict) --
UpdateToken (string) --
A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.
To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.
RuleGroupResponse (dict) --
The high-level properties of a rule group. This, along with the RuleGroup, define the rule group. You can retrieve all objects for a rule group by calling DescribeRuleGroup.
RuleGroupArn (string) --

RuleGroupName (string) --
The descriptive name of the rule group. You can't change the name of a rule group after you create it.
RuleGroupId (string) --
The unique identifier for the rule group.
Description (string) --
A description of the rule group.
Type (string) --
Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.
Capacity (integer) --
The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.
You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with DryRun set to TRUE.
RuleGroupStatus (string) --
Detailed information about the current status of a rule group.
Tags (list) --
The key:value pairs to associate with the resource.
(dict) --
A key:value pair associated with an Amazon Web Services resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each Amazon Web Services resource.
Key (string) --
The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.
Value (string) --
The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.
ConsumedCapacity (integer) --

NumberOfAssociations (integer) --
The number of firewall policies that use this rule group.
EncryptionConfiguration (dict) --
A complex type that contains the Amazon Web Services KMS encryption configuration settings for your rule group.
KeyId (string) --
The ID of the Amazon Web Services Key Management Service (KMS) customer managed key. You can use any of the key identifiers that KMS supports, unless you're using a key that's managed by another account. If you're using a key managed by another account, then specify the key ARN. For more information, see Key ID in the Amazon Web Services KMS Developer Guide.
Type (string) --
The type of Amazon Web Services KMS key to use for encryption of your Network Firewall resources.
SourceMetadata (dict) --
A complex type that contains metadata about the rule group that your own rule group is copied from. You can use the metadata to track the version updates made to the originating rule group.
SourceArn (string) --
The Amazon Resource Name (ARN) of the rule group that your own rule group is copied from.
SourceUpdateToken (string) --
The update token of the Amazon Web Services managed rule group that your own rule group is copied from. To determine the update token for the managed rule group, call DescribeRuleGroup.
SnsTopic (string) --
The Amazon Resource Name (ARN) of the Amazon Simple Notification Service SNS topic that's used to record changes to the managed rule group. You can subscribe to the SNS topic to receive notifications when the managed rule group is modified, such as for new versions and for version expiration. For more information, see the Amazon Simple Notification Service Developer Guide..
LastModifiedTime (datetime) --
The last time that the rule group was changed.
AnalysisResults (list) --
The list of analysis results for AnalyzeRuleGroup. If you set AnalyzeRuleGroup to TRUE in CreateRuleGroup, UpdateRuleGroup, or DescribeRuleGroup, Network Firewall analyzes the rule group and identifies the rules that might adversely effect your firewall's functionality. For example, if Network Firewall detects a rule that's routing traffic asymmetrically, which impacts the service's ability to properly process traffic, the service includes the rule in the list of analysis results.
(dict) --
The analysis result for Network Firewall's stateless rule group analyzer. Every time you call CreateRuleGroup, UpdateRuleGroup, or DescribeRuleGroup on a stateless rule group, Network Firewall analyzes the stateless rule groups in your account and identifies the rules that might adversely effect your firewall's functionality. For example, if Network Firewall detects a rule that's routing traffic asymmetrically, which impacts the service's ability to properly process traffic, the service includes the rule in a list of analysis results.
The AnalysisResult data type is not related to traffic analysis reports you generate using StartAnalysisReport. For information on traffic analysis report results, see AnalysisTypeReportResult.
IdentifiedRuleIds (list) --
The priority number of the stateless rules identified in the analysis.
(string) --
IdentifiedType (string) --
The types of rule configurations that Network Firewall analyzes your rule groups for. Network Firewall analyzes stateless rule groups for the following types of rule configurations:
STATELESS_RULE_FORWARDING_ASYMMETRICALLY Cause: One or more stateless rules with the action pass or forward are forwarding traffic asymmetrically. Specifically, the rule's set of source IP addresses or their associated port numbers, don't match the set of destination IP addresses or their associated port numbers. To mitigate: Make sure that there's an existing return path. For example, if the rule allows traffic from source 10.1.0.0/24 to destination 20.1.0.0/24, you should allow return traffic from source 20.1.0.0/24 to destination 10.1.0.0/24.
STATELESS_RULE_CONTAINS_TCP_FLAGS Cause: At least one stateless rule with the action pass or forward contains TCP flags that are inconsistent in the forward and return directions. To mitigate: Prevent asymmetric routing issues caused by TCP flags by following these actions:
Remove unnecessary TCP flag inspections from the rules.
If you need to inspect TCP flags, check that the rules correctly account for changes in TCP flags throughout the TCP connection cycle, for example SYN and ACK flags used in a 3-way TCP handshake.
AnalysisDetail (string) --
Provides analysis details for the identified rule.
