ACM certificates should be tagged

Description

Flags ACM certificates that have no user-defined tags. Tags help with ownership, cost allocation, and incident triage; certificates without any non-system tag are operationally opaque.


Remediation

Apply at least one user-defined tag to every ACM certificate.

Steps

  1. Open the AWS Certificate Manager console and select the certificate.
  2. On the certificate detail page, choose Tags and then Edit.
  3. Add at least one tag with a non-aws: prefixed key (e.g. Owner, Environment, CostCenter).
  4. Save the changes.
