Maintaining developer access and privileges across code repositories is crucial for ensuring source code security, especially with the rise of cloud-based services like GitHub. Implementing effective strategies such as security scans, archiving, and branch protections are essential to securing your software supply chain. Stale repositories can become a significant security risk due to excessive access permissions and potentially outdated or unknown dependencies. To secure these repositories, companies should activate GitHub's Dependabot security scans, use advanced security scans for code and configurations, archive unused repositories, and enforce branch protections. By addressing the security holes in stale repositories, organizations can improve their overall security posture without impeding developers' day-to-day work.
