[ aws . waf ]



Associates a LoggingConfiguration with a specified web ACL.

You can access information about all traffic that AWS WAF inspects using the following steps:

  • Create an Amazon Kinesis Data Firehose . Create the data firehose with a PUT source and in the region that you are operating. However, if you are capturing logs for Amazon CloudFront, always create the firehose in US East (N. Virginia).
  • Associate that firehose to your web ACL using a PutLoggingConfiguration request.

When you successfully enable logging using a PutLoggingConfiguration request, AWS WAF will create a service linked role with the necessary permissions to write logs to the Amazon Kinesis Data Firehose. For more information, see Logging Web ACL Traffic Information in the AWS WAF Developer Guide .

See 'aws help' for descriptions of global parameters.


--logging-configuration <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--logging-configuration (structure)

The Amazon Kinesis Data Firehose that contains the inspected traffic information, the redacted fields details, and the Amazon Resource Name (ARN) of the web ACL to monitor.

Shorthand Syntax:


JSON Syntax:

  "ResourceArn": "string",
  "LogDestinationConfigs": ["string", ...],
  "RedactedFields": [
      "Data": "string"

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


LoggingConfiguration -> (structure)

The LoggingConfiguration that you submitted in the request.

ResourceArn -> (string)

The Amazon Resource Name (ARN) of the web ACL that you want to associate with LogDestinationConfigs .

LogDestinationConfigs -> (list)

An array of Amazon Kinesis Data Firehose ARNs.


RedactedFields -> (list)

The parts of the request that you want redacted from the logs. For example, if you redact the cookie field, the cookie field in the firehose will be xxx .


Specifies where in a web request to look for TargetString .

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 .
  • BODY : The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
  • SINGLE_QUERY_ARG : The parameter in the query string that you will inspect, such as UserName or SalesRegion . The maximum length for SINGLE_QUERY_ARG is 30 characters.
  • ALL_QUERY_ARGS : Similar to SINGLE_QUERY_ARG , but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString .

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 . The name of the header is not case sensitive.

When the value of Type is SINGLE_QUERY_ARG , enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion . The parameter name is not case sensitive.

If the value of Type is any other value, omit Data .
