cyberstrikeus Ensure that the /etc/default/docker file ownership is set to root:root (Manual)
Profile Applicability
- Level 2 - Docker - Linux
Description
You should verify that the /etc/default/docker file ownership and group-ownership is correctly set to root.
Rationale
The /etc/default/docker file contains sensitive parameters that may alter the behavior of the Docker daemon. It should therefore be individually owned and group owned by root to ensure that it cannot be modified by less privileged users.
Impact
None.
Audit Procedure
You should execute the command below to verify that the file is individually owned and group owned by root:
stat -c %U:%G /etc/default/docker | grep -v root:root
The command above should return no results.
Remediation
You should execute the following command
chown root:root /etc/default/docker
This sets the ownership and group ownership of the file to root.
Default Value
This file may not be present on the system, and in this case, this recommendation is not applicable.
