- **โ
Zero RPO**: Real-time replication and version control
### Availability Targets
- **RTO (Recovery Time Objective)**: 15 minutes (automatic failover)
- **RPO (Recovery Point Objective)**: 0 minutes (real-time replication)
- **Uptime Target**: 99.9% (CloudFront SLA)
- **DR Activation**: Automatic via Route53 health checks
### Availability Benefits

## ๐ Conclusion
Black Trigram implements a **security-first approach optimized for a frontend-only Korean martial arts gaming application**. While the application architecture intentionally avoids many traditional security concerns through its stateless, client-side-only design, it implements robust security where applicable.
### Current Security Strengths
1. **๐ Transport Security**: HTTPS-only communication with TLS encryption
2. **๐ก๏ธ Minimal Attack Surface**: No backend servers, databases, or user accounts to compromise
3. **๐ CI/CD Security**: Comprehensive security scanning and attestation in the build pipeline
4. **๐ฏ Privacy by Design**: No personal data collection or storage
5. **๐ Global Availability**: CDN-based delivery with natural resilience
### Security Architecture Benefits
1. **๐ฐ Cost Effective**: Minimal security infrastructure and operational costs
2. **๐ Zero Maintenance**: No ongoing security patching or monitoring required
3. **๐ High Performance**: Security controls designed for minimal performance impact
4. **๐ Global Access**: No geographic restrictions or compliance complexities
5. **๐ฎ Focus on Gaming**: Security approach supports the educational gaming mission
### Future Security Considerations
As documented in the [End-of-Life Strategy](End-of-Life-Strategy.md), any future evolution of Black Trigram toward backend services or user accounts would require implementing the traditional security layers currently marked as "not applicable."
