The container platform registry must remove old container images after updating versions have been made available.
An XCCDF Rule
Description
<VulnDiscussion>Obsolete and stale images need to be removed from the registry to ensure the container platform maintains a secure posture. While the storing of these images does not directly pose a threat, they do increase the likelihood of these images being deployed. Removing stale or obsolete images and only keeping the most recent versions of those that are still in use removes any possibility of vulnerable images being deployed.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
