📋 Deployment Security Checklist

Pre-Deployment

  • Run setup.bat to create isolated virtual environment
  • Enable HTTPS/TLS encryption (auto on GitHub Pages/Netlify)
  • Configure CORS to trusted domains only
  • Set up rate limiting (100 req/min recommended)
  • Verify admin password is not default "nufc"
  • Review and update all dependencies
  • Run security vulnerability scan
  • Configure firewall rules (allow ports: 5001, 6338, 11434)
  • Set up monitoring and alerting
  • Secure Groq API key in environment
  • Test virtual environment isolation

GitHub Pages Deployment

  • Enable GitHub Actions deployment (Settings > Pages)
  • Verify HTTPS is enforced
  • Configure custom domain with SSL (optional)
  • Review CORS settings for GitHub Pages URL
  • Deploy backend separately (Railway, Render, etc.)
  • Update API_BASE_URL in frontend HTML files

Netlify Deployment

  • Verify security headers in netlify.toml
  • Enable HTTPS redirect
  • Configure environment variables
  • Set up backend deployment separately
  • Test CORS configuration

Post-Deployment

  • Monitor access logs regularly
