Title

The container platform registry must prohibit installation or modification of container images without explicit privileged status. (Cat II impact)

Discussion

Controlling access to those users and roles that perform container platform registry functions reduces the risk of untested or potentially malicious containers from being introduced into the platform. This access may be separate from the access required to instantiate container images into services and those access requirements required to perform patch management and upgrades within the container platform. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceeds the rights of a regular user.

Check Content

Review container platform registry security settings with respect to non-administrative users' ability to create, alter, or replace container images. If any such permissions exist and are not documented and approved, this is a finding.

Fix Text

Document and obtain approval for any non-administrative users who require the ability to create, alter, or replace container images within the container platform registry. Implement the approved permissions. Revoke any unapproved permissions.
