The Gramm-Leach-Bliley Act (GLBA) sets strict standards for safeguarding customer financial data. Any system that stores, processes, or transmits that data must follow defined security rules. If your organization uses Mercurial for source control, you must ensure it is configured, monitored, and audited to meet GLBA compliance requirements.
GLBA compliance in Mercurial starts with secure access controls. Use strong authentication on every commit, push, and pull. Restrict repository access to authorized users only. Implement role-based permissions so engineers can only reach code they are cleared to handle.
Encryption is non-negotiable. GLBA demands that sensitive data in transit and at rest is protected. For Mercurial, configure HTTPS with TLS for all connections. Avoid unencrypted protocols. Store repos in encrypted volumes or file systems with robust key management.
Monitoring must be continuous. Enable detailed logging of all repository activity. Track who accessed or modified code, from which IP, and when. Maintain logs for the retention period required under GLBA. Feed these logs to a centralized SIEM for rapid response to suspicious activity.
