## Monitoring & Alerts
### Metrics to Monitor
- Authentication failures (rate, sources)
- Authorization denials (policies, resources)
- MFA failures (attempts, users)
- Token revocations (rate, reasons)
- Break-glass activations (frequency, duration)
- Secrets generation (rate, types)
- Audit log volume (events/sec)
### Alerts to Configure
- Multiple failed auth attempts (5+ in 5min)
- Break-glass session created
- Compliance report non-compliant
- Incident severity critical/high
- Token revocation spike
- KMS errors
- Audit log export failures
---
## Maintenance
### Daily
- Monitor audit logs for anomalies
- Review failed authentication attempts
- Check break-glass sessions (should be zero)
### Weekly
- Review compliance reports
- Check incident response status
- Verify backup code usage
- Review MFA device additions/removals
### Monthly
- Rotate KMS keys
- Review and update Cedar policies
- Generate compliance reports (GDPR, SOC2, ISO)
- Audit access control matrix
### Quarterly
- Full security audit
- Penetration testing
- Compliance certification review
- Update security documentation
---
## Migration Path
### From Existing System
1. **Phase 1**: Deploy security infrastructure
- KMS service
- Orchestrator with auth middleware
- Control Center
2. **Phase 2**: Migrate authentication
- Enable JWT authentication
- Migrate existing users
- Disable old auth system
3. **Phase 3**: Enable MFA
- Require MFA enrollment for admins
- Gradual rollout to all users
4. **Phase 4**: Enable Cedar authorization
- Deploy initial policies (permissive)
- Monitor authorization decisions
- Tighten policies incrementally
5. **Phase 5**: Enable advanced features
- Break-glass procedures
- Compliance reporting
- Incident response
---
## Future Enhancements
### Planned (Not Implemented)
- **Hardware Security Module (HSM)** integration
- **OAuth2/OIDC** federation
- **SAML SSO** for enterprise
- **Risk-based authentication** (IP reputation, device fingerprinting)
- **Behavioral analytics** (anomaly detection)
- **Zero-Trust Network** (service mesh integration)
### Under Consideration
- **Blockchain audit log** (immutable append-only log)
- **Quantum-resistant cryptography** (post-quantum algorithms)
- **Confidential computing** (SGX/SEV enclaves)
- **Distributed break-glass** (multi-region approval)
---
## Consequences
### Positive
✅ **Enterprise-grade security** meeting GDPR, SOC2, ISO 27001
✅ **Zero static credentials** (all dynamic, time-limited)
✅ **Complete audit trail** (immutable, GDPR-compliant)
✅ **MFA-enforced** for sensitive operations
✅ **Emergency access** with enhanced controls
✅ **Fine-grained authorization** (Cedar policies)
✅ **Automated compliance** (reports, incident response)
### Negative
⚠️ **Increased complexity** (12 components to manage)
⚠️ **Performance overhead** (~10-20ms per request)
⚠️ **Memory footprint** (~260MB additional)
⚠️ **Learning curve** (Cedar policy language, MFA setup)
⚠️ **Operational overhead** (key rotation, policy updates)
### Mitigations
- Comprehensive documentation (ADRs, guides, API docs)
- CLI commands for all operations
- Automated monitoring and alerting
- Gradual rollout with feature flags
- Training materials for operators
