2015/10/06 - AWS WAF - 28 new api methods
Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet. For each ByteMatchTuple object, you specify the following values:
Whether to insert or delete the object from the array. If you want to change a ByteMatchSetUpdate object, you delete the existing object and add a new one.
The part of a web request that you want AWS WAF to inspect, such as a query string or the value of the User-Agent header.
The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to look for. For more information, including how you specify the values for the AWS WAF API and the AWS CLI or SDKs, see TargetString in the ByteMatchTuple data type.
Where to look, such as at the beginning or the end of a query string.
Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
For example, you can add a ByteMatchSetUpdate object that matches web requests in which User-Agent headers contain the string BadBot . You can then configure AWS WAF to block those requests.
To create and configure a ByteMatchSet , perform the following steps:
Create a ByteMatchSet. For more information, see CreateByteMatchSet.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.
Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

[REQUIRED]
The ByteMatchSetId of the ByteMatchSet that you want to update. ByteMatchSetId is returned by CreateByteMatchSet and by ListByteMatchSets.
string
[REQUIRED]
The value returned by the most recent call to GetChangeToken.
list
[REQUIRED]
An array of ByteMatchSetUpdate objects that you want to insert into or delete from a ByteMatchSet. For more information, see the applicable data types:
ByteMatchSetUpdate: Contains Action and ByteMatchTuple
ByteMatchTuple: Contains FieldToMatch , PositionalConstraint , TargetString , and TextTransformation
FieldToMatch: Contains Data and Type
(dict) --
In an UpdateByteMatchSet request, ByteMatchSetUpdate specifies whether to insert or delete a ByteMatchTuple and includes the settings for the ByteMatchTuple .
Action (string) -- [REQUIRED]
Specifies whether to insert or delete a ByteMatchTuple.
ByteMatchTuple (dict) -- [REQUIRED]
Information about the part of a web request that you want AWS WAF to inspect and the value that you want AWS WAF to search for. If you specify DELETE for the value of Action , the ByteMatchTuple values must exactly match the values in the ByteMatchTuple that you want to delete from the ByteMatchSet .
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch.
Type (string) -- [REQUIRED]
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TargetString (bytes) -- [REQUIRED]
The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the values that you specified for FieldToMatch :
HEADER : The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch, for example, the value of the User-Agent or Referer header.
METHOD : The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.
URI : The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg .
If TargetString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64 encoding and include the resulting value, QmFkQm90 , in the value of TargetString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
TextTransformation (string) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on TargetString before inspecting a request for a match.
CMD_LINE
When you're concerned that attackers are injecting an operating system commandline command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)

URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want to perform any text transformations.
PositionalConstraint (string) -- [REQUIRED]
Within the portion of a web request that you want to search (for example, in the query string, if any), specify where you want AWS WAF to search. Valid values include the following:
CONTAINS
The specified part of the web request must include the value of TargetString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of TargetString , and TargetString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, TargetString must be a word, which means one of the following:

Inserts or deletes Predicate objects in a Rule . Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule , a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose you add the following to a Rule :
A ByteMatchSet that matches the value BadBot in the User-Agent header
An IPSet that matches the IP address 192.0.2.44
You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule . For a request to be blocked, the User-Agent header in the request must contain the value BadBot and the request must originate from the IP address 192.0.2.44.
To create and configure a Rule , perform the following steps:
Create and update the predicates that you want to include in the Rule .
Create the Rule . See CreateRule.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
Submit an UpdateRule request to add predicates to the Rule .
Create and update a WebACL that contains the Rule . See CreateWebACL.
If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.

Inserts or deletes ActivatedRule objects in a WebACL . Each Rule identifies web requests that you want to allow, block, or count. When you update a WebACL , you specify the following values:
A default action for the WebACL , either ALLOW or BLOCK . AWS WAF performs the default action if a request doesn't match the criteria in any of the Rules in a WebACL .
The Rules that you want to add and/or delete. If you want to replace one Rule with another, you delete the existing Rule and add the new one.
For each Rule , whether you want AWS WAF to allow requests, block requests, or count requests that match the conditions in the Rule .
The order in which you want AWS WAF to evaluate the Rules in a WebACL . If you add more than one Rule to a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . (The Rule that has the lowest value for Priority is evaluated first.) When a web request matches all of the predicates (such as ByteMatchSets and IPSets ) in a Rule , AWS WAF immediately takes the corresponding action, allow or block, and doesn't evaluate the request against the remaining Rules in the WebACL , if any.
The CloudFront distribution that you want to associate with the WebACL .
To create and configure a WebACL , perform the following steps:
Create and update the predicates that you want to include in Rules . For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.
Create and update the Rules that you want to include in the WebACL . For more information, see CreateRule and UpdateRule.
Create a WebACL . See CreateWebACL.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.

When you want to create, update, or delete AWS WAF objects, get a change token and include the change token in the create, update, or delete request. Change tokens ensure that your application doesn't submit conflicting requests to AWS WAF.
Each create, update, or delete request must use a unique change token. If your application submits a GetChangeToken request and then submits a second GetChangeToken request before submitting a create, update, or delete request, the second GetChangeToken request returns the same value as the first GetChangeToken request.
When you use a change token in a create, update, or delete request, the status of the change token changes to PENDING , which indicates that AWS WAF is propagating the change to all AWS WAF servers. Use GetChangeTokenStatus to determine the status of your change token.

ByteMatchSetId is returned by CreateByteMatchSet and by ListByteMatchSets.
Name (string) --
A friendly name or description of the ByteMatchSet. You can't change Name after you create a ByteMatchSet .
ByteMatchTuples (list) --
Specifies the bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.
(dict) --
The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch.
Type (string) --
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TargetString (bytes) --
The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the values that you specified for FieldToMatch :
HEADER : The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch, for example, the value of the User-Agent or Referer header.
METHOD : The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.
URI : The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg .
If TargetString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64 encoding and include the resulting value, QmFkQm90 , in the value of TargetString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
TextTransformation (string) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on TargetString before inspecting a request for a match.
CMD_LINE
When you're concerned that attackers are injecting an operating system commandline command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want to perform any text transformations.
PositionalConstraint (string) --
Within the portion of a web request that you want to search (for example, in the query string, if any), specify where you want AWS WAF to search. Valid values include the following:
CONTAINS
The specified part of the web request must include the value of TargetString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of TargetString , and TargetString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, TargetString must be a word, which means one of the following:
TargetString exactly matches the value of the specified part of the web request, such as the value of a header.
TargetString is at the beginning of the specified part of the web request and is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; .
TargetString is at the end of the specified part of the web request and is preceded by a character other than an alphanumeric character or underscore (_), for example, ;BadBot .
TargetString is in the middle of the specified part of the web request and is preceded and followed by characters other than alphanumeric characters or underscore (_), for example, -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of TargetString .
STARTS_WITH
The value of TargetString must appear at the beginning of the specified part of the web request.
ENDS_WITH
The value of TargetString must appear at the end of the specified part of the web request.
