cyberstrikeus Ensure that the docker.service file ownership is set to root:root (Automated)
Profile Applicability
- Level 1 - Docker - Linux
Description
You should verify that the docker.service file ownership and group ownership are correctly set to root.
Rationale
The docker.service file contains sensitive parameters that may alter the behavior of the Docker daemon. It should therefore be individually and group owned by the root user in order to ensure that it is not modified or corrupted by a less privileged user.
Impact
None.
Audit Procedure
Step 1: Find out the file location:
systemctl show -p FragmentPath docker.service
Step 2: If the file does not exist, this recommendation is not applicable. If the file exists, execute the command below including the correct file path in order to verify that the file is owned and group owned by root.
For example:
stat -c %U:%G /usr/lib/systemd/system/docker.service | grep -v root:root
The command above should not return anything.
Remediation
Step 1: Find out the file location:
systemctl show -p FragmentPath docker.service
Step 2: If the file does not exist, this recommendation is not applicable. If the file does exist, you should execute the command below, including the correct file path, in order to set the ownership and group ownership for the file to root.
For example:
chown root:root /usr/lib/systemd/system/docker.service
Default Value
This file may not be present on the system and if it is not, this recommendation is not applicable. By default, if the file is present, the correct permissions are for the ownership and group ownership to be set to "root".
