Version Control

Version control (source control) tracks changes to code and configuration, enabling collaboration, audit trails, and rollback capabilities.

Version control systems track all changes to code, providing history, collaboration, and security benefits.

Security benefits: - Complete audit trail of changes - Who changed what, when - Ability to rollback changes - Branch protection and reviews - Integration with CI/CD

Common platforms: - GitHub, GitLab, Bitbucket - Azure DevOps, AWS CodeCommit

Security best practices: - Require pull request reviews - Enable branch protection - Scan for secrets in commits - Sign commits (GPG/SSH) - Audit access permissions

Version control is essential for change management compliance.

Why It Matters

Version control is the foundation of change management compliance. It provides the audit trail auditors need to verify who made what changes, when, and with whose approval. Branch protection rules and pull request reviews serve as automated change management controls that satisfy SOC 2 requirements. Without version control, organizations cannot demonstrate the change management maturity that compliance frameworks demand.
