🔒 SECURITY CHECKLIST

Pre-Deployment Security

  • Environment Variables: All secrets stored in secure vault (AWS Secrets Manager, HashiCorp Vault)
  • Database Security: Encrypted at rest, SSL connections, least privilege access
  • API Security: Rate limiting, input validation, CORS properly configured
  • Authentication: JWT with proper expiration, 2FA enabled
  • Blockchain Security: Private keys stored securely, contract addresses verified
  • SSL/TLS: Valid certificates, proper cipher suites, HSTS enabled
  • Network Security: VPC, security groups, WAF if applicable

Post-Deployment Security

  • Penetration Testing: Third-party security assessment
  • Vulnerability Scanning: Regular dependency updates
  • Access Logging: Monitor authentication and authorization events
  • Incident Response: Plan for security incidents
  • Backup Strategy: Regular database and file backups
  • Disaster Recovery: Multi-region deployment if needed

🚨 INCIDENT RESPONSE

Monitoring Alerts

# alertmanager.yml
groups:
  - name: zerohack.rules
    rules:
      - alert: HighErrorRate
        expr: rate(http_requests_total{status=~"5.."}[5m]) > 0.1
        for: 5m
        labels:
          severity: critical
        annotations:
          summary: "High error rate detected"
          
      - alert: DatabaseDown
        expr: up{job="zerohack-database"} == 0
        for: 1m
        labels:
          severity: critical
        annotations:
          summary: "Database is down"
          
      - alert: AIModelDown
        expr: zerohack_ai_models_ready == 0
        for: 2m
        labels:
          severity: warning
        annotations:
          summary: "AI models are not ready"

Emergency Procedures

  1. Service Down: Check health endpoints, restart containers
  2. Database Issues: Check connection pool, run migrations
  3. AI Model Issues: Check model loading, restart AI service
  4. Blockchain Issues: Check RPC connectivity, verify contract addresses
  5. Security Incident: Isolate affected systems, review logs

📈 PERFORMANCE OPTIMIZATION

Backend Optimization

# Database connection pooling
DATABASE_URL = "postgresql+asyncpg://user:pass@host:5432/db?pool_size=20&max_overflow=30"

# Redis caching
CACHE_TTL = 3600  # 1 hour
CACHE_PREFIX = "zerohack:"

# Model optimization
MODEL_BATCH_SIZE = 32
MODEL_CACHE_SIZE = 1000

Frontend Optimization

// Code splitting
const Dashboard = lazy(() => import('./components/Dashboard'));
const Incidents = lazy(() => import('./components/Incidents'));

// Service worker for caching
