5.32 Ensure that the Docker socket is not mounted inside any containers (Manual)
Profile Applicability
- Level 1 - Docker - Linux
Description
The Docker socket docker.sock should not be mounted inside a container.
Rationale
If the Docker socket is mounted inside a container it could allow processes running within the container to execute Docker commands which would effectively allow for full control of the host.
Impact
None
Audit Procedure
You should run the following command:
docker ps --quiet --all | xargs docker inspect --format '{{ .Id }}: Volumes={{ .Mounts }}' | grep docker.sock
This would return any instances where docker.sock had been mapped to a container as a volume.
Remediation
You should ensure that no containers mount docker.sock as a volume.
Default Value
By default, docker.sock is not mounted inside containers.
