LoggingConfiguration - AWS WAFV2
ContentsSee Also

LoggingConfiguration

Defines an association between logging destinations and a web ACL resource, for logging from AWS WAF. As part of the association, you can specify parts of the standard logging fields to keep out of the logs and you can specify filters so that you log only a subset of the logging records.

Note

You can define one logging destination per web ACL.

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

  1. Create your logging destination. You can use an Amazon CloudWatch Logs log group, an Amazon Simple Storage Service (Amazon S3) bucket, or an Amazon Kinesis Data Firehose.

    The name that you give the destination must start with aws-waf-logs-. Depending on the type of destination, you might need to configure additional settings or permissions.

    For configuration requirements and pricing information for each destination type, see Logging web ACL traffic in the AWS WAF Developer Guide.

  2. Associate your logging destination to your web ACL using a PutLoggingConfiguration request.

When you successfully enable logging using a PutLoggingConfiguration request, AWS WAF creates an additional role or policy that is required to write logs to the logging destination. For an Amazon CloudWatch Logs log group, AWS WAF creates a resource policy on the log group. For an Amazon S3 bucket, AWS WAF creates a bucket policy. For an Amazon Kinesis Data Firehose, AWS WAF creates a service-linked role.

For additional information about web ACL logging, see Logging web ACL traffic information in the AWS WAF Developer Guide.

LogDestinationConfigs

The logging destination configuration that you want to associate with the web ACL.

Note

You can associate one logging destination to a web ACL.

Type: Array of strings

Array Members: Minimum number of 1 item. Maximum number of 100 items.

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: .*\S.*

Required: Yes

ResourceArn

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

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: .*\S.*

Required: Yes

LoggingFilter

Filtering that specifies which web requests are kept in the logs and which are dropped. You can filter on the rule action and on the web request labels that were applied by matching rules during web ACL evaluation.

Type: LoggingFilter object

Required: No

ManagedByFirewallManager

Indicates whether the logging configuration was created by AWS Firewall Manager, as part of an AWS WAF policy configuration. If true, only Firewall Manager can modify or delete the configuration.

Type: Boolean

Required: No

RedactedFields

The parts of the request that you want to keep out of the logs.

For example, if you redact the SingleHeader field, the HEADER field in the logs will be REDACTED for all rules that use the SingleHeader FieldToMatch setting.

Redaction applies only to the component that's specified in the rule's FieldToMatch setting, so the SingleHeader redaction doesn't apply to rules that use the Headers FieldToMatch.

Note

You can specify only the following fields for redaction: UriPath, QueryString, SingleHeader, and Method.

Note

This setting has no impact on request sampling. With request sampling, the only way to exclude fields is by disabling sampling in the web ACL visibility configuration.

Type: Array of FieldToMatch objects

Array Members: Maximum number of 100 items.

Required: No
