Critical Vulnerabilities include:

• Remote code execution
• Authentication bypass
• Privilege escalation
• Data exfiltration
• Supply chain attacks

High Vulnerabilities include:

• Cross-site scripting (XSS)
• SQL injection
• Insecure direct object references

GitGuard implements multiple security layers:

• Secret Scanning: Automated detection of exposed credentials
• Policy Enforcement: OPA-based security policies
• Container Security: Image scanning and signing with Cosign
• Supply Chain Security: SBOM generation and attestation
• Access Controls: RBAC with principle of least privilege
• Audit Logging: Comprehensive security event logging
• Encryption: TLS 1.3 for data in transit, AES-256 for data at rest

When deploying GitGuard:

1. Environment Security:

   • Use dedicated service accounts with minimal permissions
   • Enable audit logging for all security events
   • Regularly rotate API keys and tokens
   • Implement network segmentation

2. Configuration Security:

   • Review and customize OPA policies for your environment
   • Enable all security scanning features
   • Configure proper backup and disaster recovery
   • Use secrets management systems (not environment variables)

3. Monitoring & Alerting:

   • Monitor security events and policy violations
   • Set up alerts for critical security events
   • Regularly review access logs and user activities
   • Implement incident response procedures

Security updates are distributed through:

• GitHub Releases: Tagged releases with security patches
• Container Images: Updated images in container registry
• Security Advisories: Detailed vulnerability information
• Mailing List: security-announce@gitguard.dev (low-volume)

We operate a responsible disclosure program with recognition for security researchers:
