Goal

Detect when a user deletes a Route 53 query logging configuration.

Strategy

Monitor cloudtrail logs where @evt.name is DeleteResolverQueryLogConfig which would stop Route53 Query logging for all of the Amazon VPCs that are associated with the configuration.

Triage and response

  1. Determine if {{@userIdentity.arn}} is expected to perform the {{@evt.name}} API call.
  2. Contact the principal owner and see if this was an API call that was made by the user.
  3. If the API call was not made by the user, rotate the user credentials and investigate what other APIs were successfully accessed.

Changelog
