  • Auto-extension on activity
  • Session refresh regenerates CSRF token

Password Hashing

  • Algorithm: bcrypt

2. CSRF Protection ✅

Implementation Status: COMPLETE

Token Generation

  • Method: Web Crypto API (cryptographically secure)
  • Length: 32 bytes (64 hex characters)
  • Storage: Session-based in database

Validation

  • Enforcement: All POST/PUT/DELETE requests
  • Exemptions: GET, HEAD, OPTIONS
  • Method: Constant-time comparison (timing attack prevention)
  • Implementation: /src/lib/csrf.ts

Double-Submit Cookie Pattern

  • Cookie: nself-csrf (readable by JavaScript)
  • Header: x-csrf-token (must match cookie)
  • Rotation: Token regenerated on session refresh

Origin Validation

  • Additional Layer: Origin/Referer header validation
  • Allowed Patterns: localhost, 127.0.0.1, *.local domains
  • Production: Strict origin enforcement

3. XSS Prevention ✅

Implementation Status: COMPLETE

Input Sanitization

  • style-src 'self' 'unsafe-inline' (Tailwind requirement)
  • img-src 'self' data: https:
  • connect-src 'self' ws: wss:

Output Escaping

  resources:
    limits:
      cpus: '2'
      memory: 2G
    reservations:
      cpus: '1'
      memory: 1G

Penetration Testing Checklist

Authentication Tests

  • Brute force login (should be rate limited)
  • Session fixation (tokens regenerated on login)
  • Session hijacking (httpOnly prevents XSS theft)
  • Password complexity bypass (enforced server-side)
  • Concurrent session abuse (tracked in database)

Authorization Tests

  • Privilege escalation (single admin user)
  • Path traversal (sanitized in validation.ts)
  • Direct object reference (session required for all routes)

Input Validation Tests

  • SQL injection (parameterized queries via CLI)
  • Command injection (execFile with array args)
  • XSS injection (React escaping + CSP)
  • Path traversal (sanitizePath function)
  • Header injection (validated by Next.js)

API Security Tests

  • Rate limit bypass (IP + user agent fingerprinting)
  • CSRF bypass (token validation + origin check)
  • Mass assignment (Zod schemas whitelist fields)
  • Parameter pollution (Zod validation)

Session Management Tests

  • Session timeout (7-30 days with activity extension)
  • Logout functionality (session deleted from DB)
  • Concurrent sessions (tracked, can be revoked)
  • Session replay (CSRF token changes on refresh)

Infrastructure Tests

  • Docker escape (running as root, but isolated)
  • File upload malware (validation only, no scanning)
  • Resource exhaustion (Docker limits recommended)
  • DoS attacks (rate limiting in place)

Security Best Practices Guide

For Developers

  1. Never commit secrets - Use .env files (gitignored)
  2. Validate all input - Use Zod schemas
  3. Escape all output - Use React JSX (auto-escapes)
  4. Use parameterized queries - Via nself CLI only
  5. Keep dependencies updated - Run pnpm audit regularly
  6. Test security - Run penetration tests before releases
  7. Review code - Security review for all PRs
  8. Use HTTPS - Always in production
  9. Monitor logs - Check audit logs for suspicious activity
  10. Principle of least privilege - Minimal permissions

For Deployment

  1. Use HTTPS - Configure reverse proxy (nginx/Caddy)
  2. Set environment variables - Never hardcode secrets
  3. Enable Docker limits - CPU, memory constraints
  4. Use Docker socket proxy - For better security
  5. Configure firewall - Restrict network access
  6. Enable monitoring - Prometheus, Grafana
  7. Regular backups - Database and project data
  8. Update regularly - Apply security patches
  9. Use strong passwords - 12+ characters, complexity
  10. Enable audit logging - Monitor all access

Recommended Security Enhancements
