Security Measures

1. Authentication

  • ✅ JWT tokens (7-day expiration)
  • ✅ Password hashing (bcryptjs - 10 rounds)
  • ✅ Secure token storage
  • ✅ Token refresh mechanism (planned)

2. Authorization

  • ✅ Role-based access control (RBAC)
  • ✅ Resource ownership validation
  • ✅ Admin route protection
  • ✅ Permission middleware

3. Data Protection

  • ✅ HTTPS/TLS via Cloudflare SSL
  • ✅ SQL injection protection (Prisma)
  • ✅ XSS protection (content sanitization)
  • ✅ CSRF protection (CORS)

4. API Security

  • ✅ Rate limiting (100 req/15 min)
  • ✅ CORS validation
  • ✅ Request validation (Zod)
  • ✅ Error message sanitization

5. HTTP Security

  • ✅ Content-Security-Policy headers
  • ✅ X-Frame-Options (DENY)
  • ✅ X-Content-Type-Options (nosniff)
  • ✅ Strict-Transport-Security
  • ✅ Referrer-Policy

6. Infrastructure Security

  • ✅ Cloudflare WAF rules
  • ✅ DDoS protection (Cloudflare)
  • ✅ Bot management (Cloudflare)
  • ✅ SSL certificate management
  • ✅ Encrypted database connections

7. Application Security

  • ✅ Input validation on all endpoints
  • ✅ Output encoding
  • ✅ Secure error handling
  • ✅ Logging & monitoring
  • ✅ Regular security audits

Database Security

Connection Security

DATABASE_URL=postgresql://user:password@host:5432/db?sslmode=require

Row Level Security (RLS)

ALTER TABLE "Project" ENABLE ROW LEVEL SECURITY;

CREATE POLICY user_projects_policy ON "Project"
USING (user_id = auth.uid());

Backup Security

  • ✅ Automated daily backups
  • ✅ Encrypted backups
  • ✅ Geo-redundant storage
  • ✅ Tested recovery procedures

API Security Headers

Content-Security-Policy: default-src 'self'
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block
Strict-Transport-Security: max-age=31536000
Referrer-Policy: strict-origin-when-cross-origin
Permissions-Policy: geolocation=(), microphone=()

Password Requirements

  • Minimum 8 characters
  • At least 1 uppercase letter
  • At least 1 lowercase letter
  • At least 1 number

Token Management

// Token generation
const token = jwt.sign(
  { id, email, role },
  JWT_SECRET,
  { expiresIn: '7d' }
);

// Token verification
const decoded = jwt.verify(token, JWT_SECRET);

// Token refresh (planned)
// Long-lived refresh tokens
// Short-lived access tokens

Compliance

Standards Compliance

  • ✅ OWASP Top 10 protection
  • ✅ GDPR compliance considerations
  • ✅ Data privacy best practices
  • ✅ Secure coding standards

Security Checklist

  • ✅ Regular dependency updates
  • ✅ Security headers enabled
  • ✅ CORS properly configured
  • ✅ Rate limiting enabled
  • ✅ Input validation everywhere
  • ✅ Output encoding implemented
  • ✅ Error handling secure
  • ✅ Logging enabled
  • ✅ Monitoring active

Incident Response

Procedures

  1. Detect incident
  2. Contain impact
  3. Eradicate threat
  4. Recover systems
  5. Document & review
  6. Improve security

Contact

Regular Security Reviews

  • ✅ Quarterly security audits
  • ✅ Dependency vulnerability scanning
  • ✅ Penetration testing annually
  • ✅ Code security reviews (every PR)
  • ✅ Infrastructure assessment

Future Security Enhancements

  • Two-factor authentication (2FA)
  • OAuth 2.0 / OpenID Connect
  • API key management
  • End-to-end encryption for sensitive data
  • Advanced threat detection
  • Security headers CSP enhancement
  • Database encryption at rest
