Self-Hosted Runner Hardening
When to Use This Skill
Hardening is not optional. Every layer of defense you skip is an attack vector you gift to adversaries. Deploy runners defensively or accept the breach.
The Default Is Insecure
A default runner installation has root access, unrestricted network, cloud metadata endpoints, persistent filesystem, and ambient credentials. One malicious workflow means full infrastructure compromise. Apply every hardening layer.
Implementation
See the full implementation guide in the source documentation.
Examples
See examples.md for code examples.
