How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Inspect the Agent Skill at https://github.com/CyberStrikeus/CyberStrike/blob/HEAD/.cyberstrike/skill/CIS_benchmarks/Server_Software/Docker/CIS_Docker_Benchmark_v1.8.0/cis-docker-3.5/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/cis-docker-3-5, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
Ensure that the /etc/docker directory ownership is set to root:root (Automated)
Profile Applicability
- Level 1 - Docker - Linux
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.
