OSPS-AC-03 Protect the Primary Branch from Accidental Modification (maturity levels 1, 2, 3). Requirement: When a direct commit is attempted on the project's primary branch, an enforcement mechanism MUST prevent the change from being applied. Objective of the control: Reduce the risk of accidental changes or deletion of the primary branch of the project's repository by preventing unintentional modification. Recommendation: If the VCS is centralized, set branch protection on the primary branch in the project's VCS. Alternatively, use a decentralized approach, like the Linux kernel's, where changes are first proposed in another repository, and merging changes into the primary repository requires a specific separate act.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
