System Documentation

What problem does it solve?

Self-hosted GitHub Actions runners are exposed to OS-level and network vulnerabilities; this skill provides a comprehensive, defense-in-depth hardening guide to reduce attack surface and protect credentials.

Core Features & Use Cases

  • OS-level hardening, user and permission controls, and service isolation for runner processes.
  • Network isolation, process confinement (AppArmor), and file system restrictions to prevent data exfiltration and persistence.
  • Use Case: When you deploy self-hosted runners in CI, apply these steps to harden the host, isolate the runner, and enable auditable security controls.

Quick Start

Run the self-hosted-runner-hardening skill on a Linux host to bootstrap security baselines and runtime protections.
