3.16 Ensure that Docker socket file permissions are set to 660 or more restrictive

Information

Verify that the Docker socket file has permissions of 660 or more restrictive.
Rationale:
Only root and members of docker group should be allowed to read and write to default Docker Unix socket. Hence, the Docket socket file must have permissions of 660 or more restrictive.

Solution

chmod 660 /var/run/docker.sock
This would set the file permissions of the Docker socket file to 660.
Impact:
None.
Default Value:
By default, the permissions for Docker socket file is correctly set to 660.
