cyberstrikeus CIS Docker Benchmark v1.7.0 - Control 3.17
Description
You should verify that the daemon.json file individual ownership and group ownership is correctly set to root, if it is in use.
Rationale
The daemon.json file contains sensitive parameters that could alter the behavior of the docker daemon. It should therefore be owned and group owned by root to ensure it can not be modified by less privileged users.
Impact
None.
Audit Procedure
You should execute the command below to verify that the file is owned and group owned by root:
stat -c %U:%G /etc/docker/daemon.json | grep -v root:root
The command above should not return any results or, if there is no daemon.json file present it will return:
stat: cannot stat '/etc/docker/daemon.json': No such file or directory
Remediation
If the daemon.json file is present, you should execute the command below:
chown root:root /etc/docker/daemon.json
This sets the ownership and group ownership for the file to root.
Default Value
This file may not be present on the system, and in that case, this recommendation is not applicable.
