In Azure Repos, Role-Based Access Control (RBAC) is how you configure permissions in the source control repository to secure code, meet compliance rules, and support teamwork. You assign built-in or custom roles to users and groups at the repository, branch, and path levels. You also set up branch protection policies to enforce review and testing before code is merged. The security evaluation tool helps you audit effective permissions so you can spot gaps and fix them.
Azure Repos provides built-in roles that give different levels of access. A Contributor can make changes and push code. A Reader can view the code but cannot change it. An Administrator has full control over repository settings, including permissions. For more precise needs, you can create custom roles that allow only specific actions, such as editing a certain folder or approving pull requests. Roles can be assigned at the repository level, the branch level, or even at the path level inside a repository, so you can decide exactly who can touch what.
Branch protection policies keep the main codebase stable by preventing direct pushes to important branches. For example, the policy can require that every change first goes through a pull request and gets at least one reviewer’s approval. It can also enforce that a build validation step (like running tests) must succeed before the merge happens. These policies make sure that all changes are reviewed and tested, which reduces the chance of introducing broken or insecure code.
Azure provides tools to check who has what permissions and to verify that your setup follows your organization’s security rules. The security evaluation tool shows you the effective permissions on a repository, branch, or path, so you can see if a user has more access than they should. You can also use audit logs to track who changed permissions and when. By regularly auditing the effective permissions, you can catch unauthorized access early and adjust roles or policies to stay compliant.
