5.2.9 Minimize the admission of containers with capabilities assigned


Do not generally permit containers with capabilities


Containers run with a default set of capabilities as assigned by the Container Runtime. Capabilities are parts of the rights generally granted on a Linux system to the root user.

In many cases applications running in containers do not require any capabilities to operate, so from the perspective of the principal of least privilege use of capabilities should be minimized.


Pods with containers require capabilities to operate will not be permitted.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.


Review the use of capabilities in applications running on your cluster. Where a namespace contains applications which do not require any Linux capabilities to operate consider adding a PSP which forbids the admission of containers which do not drop all capabilities.

Default Value:

By default, PodSecurityPolicies are not defined.
