Discussion

Using the --privileged flag gives all Linux Kernel Capabilities to the container, thus overwriting the --cap-add and --cap-drop flags. The --privileged flag gives all capabilities to the container, and it also lifts all the limitations enforced by the device cgroup controller. Any container that requires this privilege must be documented and approved.

Check Content

When using Kubernetes orchestration, this check is Not Applicable. 

When using Swarm orchestration, execute the following command as a trusted user on the host operating system via CLI:

docker ps --quiet --all | grep -iv "MKE\|kube\|dtr" | awk '{print $1}' | xargs docker inspect --format '{{ .Id }}: Privileged={{ .HostConfig.Privileged }}'

Verify in the output that no containers are running with the --privileged flag. If there are, this is a finding.
