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
- Determine if {{@userIdentity.arn}} is expected to perform the {{@evt.name}} API call.
- Contact the principal owner and see if this was an API call that was made by the user.
- If the API call was not made by the user, rotate the user credentials and investigate what other APIs were successfully accessed.
Changelog
- 7 April 2022 - Updated rule query and signal message.
- 5 January 2023 - Updated severity.
