Excitingly, another Microsoft repository has integrated Harden-Runner, further solidifying its place as a critical CI/CD security tool. A recent pull request titled “Hardening GitHub Runners” was created by a Microsoft developer in the vsts-extension-retrospectives repository, marking another vote of confidence from a major tech player. This PR emphasizes Harden-Runner’s core features:

  • Baseline Creation: Tracks outbound network calls, processes, and file writes per job across multiple runs.
  • Anomaly Detection: Alerts on any unexpected deviations from the job-specific baseline.
