cyberstrikeus Ensure that the /etc/sysconfig/docker file permissions are set to 644 or more restrictively (Manual)
Profile Applicability
- Level 2 - Docker - Linux
Description
You should verify that the /etc/sysconfig/docker file permissions are correctly set to 644 or more restrictively.
Rationale
The /etc/sysconfig/docker file contains sensitive parameters that may alter the behavior of the Docker daemon. It should therefore be writeable only by root in order to ensure that it is not modified by less privileged users.
Impact
None.
Audit Procedure
You should execute the command below to verify that the file permissions are correctly set to 644 or more restrictively:
stat -c %a /etc/sysconfig/docker
Remediation
You should execute the following command:
chmod 644 /etc/sysconfig/docker
This sets the file permissions for this file to 644.
Default Value
This file may not be present on the system and in this case, this recommendation is not applicable.
