GitHub Runner Security Overview

About

This skill provides a comprehensive security framework for deploying and managing self-hosted GitHub Actions runners. It guides users through critical security trade-offs, comparing GitHub-hosted versus self-hosted options while identifying major attack vectors like persistent state, credential theft, and lateral movement. By detailing secure deployment models—from ephemeral VMs to hardened container-based systems—this skill helps DevOps and security engineers build resilient, isolated CI/CD pipelines that protect internal networks and cloud resources.
