cyberstrikeus CIS Docker Benchmark v1.7.0 - Control 3.11
Description
You should verify that the Docker server certificate file (the file that is passed along with the --tlscert parameter) is individual owned and group owned by root.
Rationale
The Docker server certificate file should be protected from any tampering. It is used to authenticate the Docker server based on the given server certificate. It must therefore be individually owned and group owned by root to prevent modification by less privileged users.
Impact
None.
Audit Procedure
You should execute the command below to verify that the Docker server certificate file is individually owned and group owned by root:
stat -c %U:%G <path to Docker server certificate file> | grep -v root:root
The above command should return no results.
Remediation
You should run the following command:
chown root:root <path to Docker server certificate file>
This sets the individual ownership and the group ownership for the Docker server certificate file to root.
Default Value
By default, the ownership and group-ownership for Docker server certificate file is correctly set to root.
