What it means
Branch protection governance enforces review, status checks, signed or attributable changes, restricted force operations, and controlled exceptions on important source branches.
Why it matters
Source controls are foundational evidence only when individuals and automation cannot bypass them silently.
Practical focus
- Define the system boundary, accountable owner, approved purpose, material risks, and decision authority for Branch Protection Governance
- Require pull requests, independent review, passing checks, protected administrators, controlled merges, restricted force pushes, and logged emergency overrides.
- Collect and protect this evidence: repository rules, change history, reviews, check results, override events, administrator changes, and periodic access reviews.
- Exercise this failure scenario as a planned test: a repository administrator disables protection, pushes unreviewed code, and restores the rule without an alert.
Common mistakes
- Using the label Branch Protection Governance without defining the exact systems, data, people, decisions, and time period in scope
- Treating a policy statement or tool demonstration as proof that Branch Protection Governance operates consistently in production
- Failing to retain repository rules, change history, reviews, check results, override events, administrator changes, and periodic access reviews in a form that lets an independent reviewer reconstruct decisions and changes
- Testing only the normal path and never rehearsing what happens when a repository administrator disables protection, pushes unreviewed code, and restores the rule without an alert.
