Amazon WAF information in Amazon CloudTrail

All Amazon WAF actions are logged by Amazon CloudTrail and are documented in the Amazon WAF API Reference. For example, calls to ListWebACL, UpdateWebACL, and DeleteWebACL generate entries in the CloudTrail log files.

Every event or log entry contains information about who generated the request. The identity information helps you determine the following:

  • Whether the request was made with root user credentials

  • Whether the request was made with temporary security credentials for a role or federated user

  • Whether the request was made by another Amazon service

For more information, see CloudTrail userIdentity Element.

Example: Amazon WAF log file entries

A trail is a configuration that enables delivery of events as log files to an Amazon S3 bucket that you specify. Amazon CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files are not an ordered stack trace of the public API calls, so they do not appear in any specific order.

The following are examples of CloudTrail log entries for Amazon WAF web ACL operations.
