Security Best Practices

# MCPCodex Security Best Practices Checklist

## 🔐 Authentication & Authorization
- [ ] Implement multi-factor authentication (MFA)
- [ ] Use strong password policies (12+ chars, complexity)
- [ ] Implement OAuth 2.0 + PKCE for client authentication
- [ ] Use JWT tokens with short expiration times
- [ ] Implement proper session management
- [ ] Use role-based access control (RBAC)
- [ ] Implement API key rotation policies
- [ ] Enable audit logging for authentication events

## 🛡️ Data Protection
- [ ] Encrypt data at rest using AES-256
- [ ] Use TLS 1.3 for data in transit
- [ ] Implement end-to-end encryption for sensitive data
- [ ] Use secure key management (AWS KMS, HashiCorp Vault)
- [ ] Implement data classification policies
- [ ] Use secure backup and recovery procedures
- [ ] Implement data retention policies
- [ ] Use secure data disposal methods

## 🔍 AI Model Security
- [ ] Implement model input validation
- [ ] Use prompt injection prevention
- [ ] Implement output filtering and sanitization
- [ ] Use model versioning and integrity checks
- [ ] Implement context isolation between users
- [ ] Use secure model hosting and deployment
- [ ] Implement model access controls
- [ ] Monitor for adversarial attacks

## 🌐 Infrastructure Security
- [ ] Use infrastructure as code (IaC)
- [ ] Implement network segmentation
- [ ] Use Web Application Firewall (WAF)
- [ ] Implement DDoS protection
- [ ] Use secure container images
- [ ] Implement vulnerability scanning
- [ ] Use security monitoring and SIEM
- [ ] Implement incident response procedures

## 📝 Compliance & Governance
- [ ] Implement GDPR compliance measures
- [ ] Use SOC 2 Type II controls
- [ ] Implement PCI DSS for payment data
- [ ] Use HIPAA controls for healthcare data
- [ ] Implement data privacy controls
- [ ] Use regular security assessments
- [ ] Implement security training programs
- [ ] Use third-party security audits
