Ensure that the /etc/docker directory ownership is set to root:root (Automated)
Profile Applicability
Description
You should verify that the /etc/docker directory ownership and group ownership is correctly set to root.
Rationale
The /etc/docker directory contains certificates and keys in addition to various other sensitive files. It should therefore be individual owned and group owned by root in order to ensure that it can not be modified by less privileged users.
Impact
None.
Audit Procedure
You should execute the command below to verify that the directory is owned and group owned by root:
stat -c %U:%G /etc/docker | grep -v root:root
This command should not return any data.
Remediation
To resolve this issue you should run the following command:
chown root:root /etc/docker
This sets the ownership and group ownership for the directory to root.
Default Value
By default, the ownership and group ownership for this directory is correctly set to root.
