cyberstrikeus 5.1.13 Minimize access to the service account token creation (Manual)
Profile Applicability
- Level 1 - Master Node
Description
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 This could allow for privilege escalation and persistent access to the cluster, even if the users account has been revoked.
Rationale
The ability to create service account tokens should be limited.
Audit
Review the users who have access to create the token sub-resource of serviceaccount objects in the Kubernetes API.
Remediation
Where possible, remove access to the token sub-resource of serviceaccount objects.
