client.create_custom_data_identifier(
    clientToken='string',
    description='string',
    ignoreWords=[
        'string',
    ],
    keywords=[
        'string',

        },
    ],
    tags={
        'string': 'string'
    }
)

type clientToken:

string

param clientToken:

A unique, case-sensitive token that you provide to ensure the idempotency of the request.

This field is autopopulated if not provided.

type description:

string

param description:

A custom description of the custom data identifier. The description can contain as many as 512 characters.

We strongly recommend that you avoid including any sensitive data in the description of a custom data identifier. Other users of your account might be able to see the identifier's description, depending on the actions that they're allowed to perform in Amazon Macie.

type ignoreWords:

list

param ignoreWords:

An array that lists specific character sequences (ignore words) to exclude from the results. If the text matched by the regular expression contains any string in this array, Amazon Macie ignores it. The array can contain as many as 10 ignore words. Each ignore word can contain 4-90 UTF-8 characters. Ignore words are case sensitive.

(string) --

type keywords:

list

param keywords:

An array that lists specific character sequences (keywords), one of which must be within proximity (maximumMatchDistance) of the regular expression to match. The array can contain as many as 50 keywords. Each keyword can contain 3-90 UTF-8 characters. Keywords aren't case sensitive.

(string) --

type maximumMatchDistance:

integer

param maximumMatchDistance:

The maximum number of characters that can exist between text that matches the regular expression and the character sequences specified by the keywords array. Amazon Macie includes or excludes a result based on the proximity of a keyword to text that matches the regular expression. The distance can be 1-300 characters. The default value is 50.

type name:

string

param name:

A custom name for the custom data identifier. The name can contain as many as 128 characters.

We strongly recommend that you avoid including any sensitive data in the name of a custom data identifier. Other users of your account might be able to see the identifier's name, depending on the actions that they're allowed to perform in Amazon Macie.

type regex:

string

param regex:

The regular expression (regex) that defines the pattern to match. The expression can contain as many as 512 characters.

type severityLevels:

list

param severityLevels:

The severity to assign to findings that the custom data identifier produces, based on the number of occurrences of text that matches the custom data identifier's detection criteria. You can specify as many as three SeverityLevel objects in this array, one for each severity: LOW, MEDIUM, or HIGH. If you specify more than one, the occurrences thresholds must be in ascending order by severity, moving from LOW to HIGH. For example, 1 for LOW, 50 for MEDIUM, and 100 for HIGH. If an S3 object contains fewer occurrences than the lowest specified threshold, Amazon Macie doesn't create a finding.

If you don't specify any values for this array, Macie creates findings for S3 objects that contain at least one occurrence of text that matches the detection criteria, and Macie assigns the MEDIUM severity to those findings.

(dict) --

Specifies a severity level for findings that a custom data identifier produces. A severity level determines which severity is assigned to the findings, based on the number of occurrences of text that matches the custom data identifier's detection criteria.
- occurrencesThreshold (integer) -- [REQUIRED]
  
  The minimum number of occurrences of text that must match the custom data identifier's detection criteria in order to produce a finding with the specified severity (severity).
- severity (string) -- [REQUIRED]
  
  The severity to assign to a finding if the number of occurrences is greater than or equal to the specified threshold (occurrencesThreshold) and, if applicable, is less than the threshold for the next consecutive severity level for the custom data identifier.

type tags:

dict

param tags:

A map of key-value pairs that specifies the tags to associate with the custom data identifier.

A custom data identifier can have a maximum of 50 tags. Each tag consists of a tag key and an associated tag value. The maximum length of a tag key is 128 characters. The maximum length of a tag value is 256 characters.

Response Structure

(dict) --

The request succeeded.
- arn (string) --
  
  The Amazon Resource Name (ARN) of the custom data identifier.
- createdAt (datetime) --
  
  The date and time, in UTC and extended ISO 8601 format, when the custom data identifier was created.
- deleted (boolean) --
  
  Specifies whether the custom data identifier was deleted. If you delete a custom data identifier, Amazon Macie doesn't delete it permanently. Instead, it soft deletes the identifier.
- description (string) --
  
  The custom description of the custom data identifier.
- id (string) --
  
  The unique identifier for the custom data identifier.
- ignoreWords (list) --
  
  An array that lists specific character sequences (ignore words) to exclude from the results. If the text matched by the regular expression contains any string in this array, Amazon Macie ignores it. Ignore words are case sensitive.
  - (string) --
- keywords (list) --
  
  An array that lists specific character sequences (keywords), one of which must be within proximity (maximumMatchDistance) of the regular expression to match. Keywords aren't case sensitive.
  - (string) --
- maximumMatchDistance (integer) --
  
  The maximum number of characters that can exist between text that matches the regular expression and the character sequences specified by the keywords array. Amazon Macie includes or excludes a result based on the proximity of a keyword to text that matches the regular expression.

  The custom name of the custom data identifier.
- regex (string) --
  
  The regular expression (regex) that defines the pattern to match.
- severityLevels (list) --
  
  Specifies the severity that's assigned to findings that the custom data identifier produces, based on the number of occurrences of text that matches the custom data identifier's detection criteria. By default, Amazon Macie creates findings for S3 objects that contain at least one occurrence of text that matches the detection criteria, and Macie assigns the MEDIUM severity to those findings.
  - (dict) --
    
    Specifies a severity level for findings that a custom data identifier produces. A severity level determines which severity is assigned to the findings, based on the number of occurrences of text that matches the custom data identifier's detection criteria.

    - severity (string) --
      
      The severity to assign to a finding if the number of occurrences is greater than or equal to the specified threshold (occurrencesThreshold) and, if applicable, is less than the threshold for the next consecutive severity level for the custom data identifier.
