DevOps & Securitycis-docker-v170-3.13Cis Docker V170 3.13 is an Agent Skill for devops & security published in the CyberStrikeus/CyberStrike repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Ensure that the Docker server certificate key file ownership is set to root:root
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_v1.7.0/cis-docker-v170-3.13/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/cis-docker-v170-3-13, but wait for my approval before writing files or running scripts.

CIS Docker Benchmark v1.7.0 - Control 3.13
Description
You should verify that the Docker server certificate key file (the file that is passed along with the --tlskey parameter) is individually owned and group owned by root.
Rationale
The Docker server certificate key file should be protected from any tampering or unneeded reads/writes. As it holds the private key for the Docker server certificate, it must be individually owned and group owned by root to ensure that it cannot be accessed by less privileged users.
Impact
None.
Audit Procedure
You should execute the command below to verify that the Docker server certificate key file is individually owned and group owned by root:
stat -c %U:%G <path to Docker server certificate key file> | grep -v root:root
The command above should return no results.
Remediation
You should execute the following command:
chown root:root <path to Docker server certificate key file>
This sets the individual ownership and group ownership for the Docker server certificate key file to root.
Default Value
By default, the individual ownership and group ownership for the Docker server certificate key file is correctly set to root.
