GitHub Collaboration and Security

Operate GitHub as a governed engineering platform for repositories, reviews, planning, packages, releases, automation, secrets, and software-supply-chain security.

From concept to production evidence

Protect the default branch, require review and automated evidence, scope credentials to the environment, publish immutable artifacts, and make repository ownership explicit.

Learning outcomes

  • Configure protected collaboration workflows
  • Use issues and projects to connect work with code
  • Secure Actions, secrets, packages, and releases
  • Apply CODEOWNERS and review policy
  • Use dependency and repository security controls

GitHub Collaboration and Security end-to-end flow

Use this sequence as the operating backbone for every submodule note and hands-on exercise.

  6. 06
    Monitor dependenciesGitHub Collaboration and Security stage 6: monitor dependencies with an auditable result before the next stage begins.

Govern a GitHub repository

  1. Create teams and repository permissions
  2. Configure branch protection and CODEOWNERS
  3. Add pull-request checks
  4. Publish a signed release package
  5. Enable security and dependency alerts
