Branch protection is a set of source control rules that restrict how important branches can be changed, merged, or deleted. It matters because sensitive branches often represent production-bound code and deserve stricter control than ordinary working branches.
What is Branch Protection?
Protection rules may require review, passing checks, signed commits, restricted pushes, or merge policies before changes can land. These controls reduce accidental breakage and make malicious or rushed changes harder to slip into trusted branches.
What Branch Protection Commonly Supports
Common uses include release hardening, code governance, change control, and CI/CD trust.
Branch Protection vs. Open Direct Push Model
Branch protection adds policy and review around critical code paths. Open direct push models allow more unsupervised change into sensitive branches.
Frequently Asked Questions
Why protect branches?
Because important code paths are a frequent target for both accidental errors and deliberate tampering.
Does branch protection replace code review culture?
No. It reinforces process technically, but healthy review discipline still matters.
