## 🎯 **Purpose Statement**

**Black Trigram's** business continuity framework demonstrates how **systematic recovery planning directly enables both educational resilience and cultural preservation excellence.** Our classification-driven continuity approach serves as both operational necessity and demonstration of enterprise-grade security practices for an open-source educational gaming platform.

This plan ensures Korean martial arts education can continue during and after disruptive events, based on the [Classification Framework](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) impact analysis and recovery requirements. Our transparent continuity planning showcases how methodical preparation creates educational value through reduced downtime and enhanced service reliability for authentic Korean martial arts training.

*— James Pether Sörling, CEO/Founder*

## 🎯 Purpose & Scope

This Business Continuity Plan (BCP) establishes procedures to maintain and rapidly restore the Black Trigram Korean martial arts combat simulator during disruptions. As a frontend-only educational gaming platform with no backend infrastructure or persistent user data, our continuity strategy focuses on multi-region AWS CloudFront + S3 availability, GitHub Pages disaster recovery, source code protection, and build pipeline resilience.

## 🚨 Incident Response Procedures

### **1. CloudFront/S3 Outage**
**Detection:** Route53 health checks, CloudWatch alarms, or user reports.

**Immediate Actions:**
- Confirm outage via AWS Service Health Dashboard
- Verify Route53 health check status
- Automatic failover to GitHub Pages DR (if Route53 configured)
- Manual DNS update to GitHub Pages if automatic failover fails
- Communicate status to users via status page and social media
- Check S3 backup region availability

**Escalation:** If outage exceeds 15 minutes without automatic failover, escalate to CTO and manually switch DNS.

### **2. Route53 DNS Failure**
**Detection:** DNS resolution failures, health check alerts.

**Immediate Actions:**
- Verify AWS account status and billing
- Check Route53 service status
- Notify Response Team immediately
- Prepare manual DNS updates at domain registrar
- Communicate with AWS Support (Enterprise Support)

**Escalation:** Critical incident - immediate CEO and CTO notification required.

### **3. Repository Compromise or Loss**
**Detection:** Security alert, unauthorized commit, or repository inaccessible.

**Immediate Actions:**
- Restrict repository access
- Notify Security Lead and CEO
- Initiate investigation and restore from latest backup if needed
- Communicate with affected contributors

**Escalation:** If data loss is confirmed, follow Recovery Strategies and notify all stakeholders.

### **4. Build Pipeline Failure**
**Detection:** Build failures, deployment errors, or CI/CD alerts.

**Immediate Actions:**
- Review build logs and error messages
- Roll back to last successful build if possible
- Notify DevOps Lead

**Escalation:** If unresolved after 1 hour, escalate to CTO and consider manual deployment.
