The GitHub Enterprise Delete Branch Ruleset is designed to identify and alert on deletion events of branch protection rules within GitHub Enterprise's audit logs. This analytic targets key elements such as actor identity, repository details, and metadata surrounding deletion actions to deny unauthorized changes in critical repositories. The rule helps discern potentially malicious behavior, where an adversary may disable security safeguards designed to enforce code review processes, thereby increasing the risk of malicious code insertion or compromise of supply chain integrity. Such deletions can indicate strategic attempts to undermine security postures by allowing direct pushes of unverified code into critical branches, thus facilitating code tampering, vulnerabilities, and potential exploitation. This rule serves an essential function in maintaining oversight and control over repository integrity.
