5.1.13 Minimize access to the service account token creation

Information

Users with rights to create new service account tokens at a cluster level, can create long-lived privileged credentials in the cluster. This could allow for privilege escalation and persistent access to the cluster, even if the users account has been revoked.

The ability to create service account tokens should be limited.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Where possible, remove access to the token sub-resource of serviceaccount objects.
