Security Checklist
Security Basics:
- [ ] Authentication required for protected routes
- [ ] Passwords hashed (bcrypt/argon2), never stored plain text
- [ ] API keys in environment variables, not code
- [ ] HTTPS only in production
- [ ] Input validated on server side
- [ ] SQL injection prevented (use parameterized queries)
- [ ] XSS prevented (sanitize user input)
- [ ] CSRF tokens on forms
- [ ] Rate limiting on API endpoints
- [ ] User sessions expire (30min-1hr typical)
See COMMON-VULNS.md for detailed checks.
Critical: Never Store These in Code
Move to environment variables:
- Database passwords
- API keys (Stripe, SendGrid, etc)
- JWT secrets
- OAuth client secrets
- Encryption keys
Tell AI:
Store API keys in .env file, not in code.
Add .env to .gitignore.
Access via process.env.API_KEY
Authentication Basics
Minimum requirements:
- Passwords: 8+ chars, require number/symbol
- Hash passwords (bcrypt with 10+ rounds)
- Email verification for signups
- Password reset via email only
- Sessions expire (30-60 min idle)
- Logout clears session completely
Tell AI:
Add authentication:
- bcrypt for password hashing (12 rounds)
- Email verification required
- Session timeout: 30 minutes
- Password requirements: 8+ chars, 1 number, 1 symbol
See SECURITY-PROMPTS.md for implementation details.
Data Protection
Always encrypt:
- Passwords (hashed, not encrypted)
- Payment info (use Stripe, don't store cards)
- Personal identifiable information (PII)
Never log:
- Passwords (even hashed)
- Credit card numbers
- API keys
- Session tokens
Tell AI:
Never log sensitive data.
Replace passwords/tokens with "[REDACTED]" in logs.
API Security
Required for all API endpoints:
- Authentication check
- Rate limiting (prevent abuse)
- Input validation
- Error messages don't leak info
Tell AI:
Add to all API routes:
- Require valid auth token
- Rate limit: 100 requests/minute per IP
- Validate all inputs (reject invalid)
- Generic error messages (no stack traces to users)
Common Vulnerabilities
Most common in AI-built apps:
- Exposed API keys - In code instead of .env
- No rate limiting - APIs can be spammed
- Missing auth checks - Routes accessible without login
- SQL injection - Raw SQL with user input
- XSS attacks - Unescaped user content displayed
See COMMON-VULNS.md for how to check.
Security Prompts for AI
Adding authentication:
Add authentication to this route.
Require valid JWT token.
Return 401 if missing/invalid.
Don't expose error details.
Rate limiting:
Add rate limiting:
- 100 requests/minute per IP
- Return 429 "Too many requests" if exceeded
- Use sliding window, not fixed
Input validation:
Validate all user inputs:
- Email: valid format
- Password: 8+ chars, 1 number, 1 symbol
- Username: alphanumeric only, 3-20 chars
Reject invalid input with clear error message
See SECURITY-PROMPTS.md for more.
Pre-Launch Security Review
Before deploying:
Production Security:
- [ ] All secrets in environment variables
- [ ] HTTPS enforced (no HTTP)
- [ ] Database backups configured
- [ ] Rate limiting on all APIs
- [ ] Error pages don't show stack traces
- [ ] Admin routes protected
- [ ] File uploads validated (type, size)
- [ ] CORS configured (not wildcard "*")
When to Get Security Audit
Signs you need expert review:
- Handling payments directly (not Stripe)
- Storing health/financial data
- Multi-tenant with data isolation
- Over 1,000 users
- Processing sensitive PII
For most MVPs: Following this checklist is sufficient.
Common Founder Mistakes
| Mistake | Fix |
|---|---|
| API keys in code | Move to .env |
| No rate limiting | Add to all endpoints |
| Plain text passwords | Use bcrypt |
| HTTP in production | Force HTTPS |
| Accepting all CORS | Whitelist domains |
| No input validation | Validate server-side |
| Detailed error messages | Generic messages only |
Quick Wins
Easy security improvements:
- Add Helmet.js (Node) - Sets security headers
- Use HTTPS everywhere - Force in production
- Add rate limiting - Prevents abuse
- Environment variables - Keep secrets safe
- Update dependencies - Fix known vulnerabilities
Tell AI:
Add helmet.js for security headers.
Configure for production (HTTPS, CSP, XSS protection).
Testing Security
Quick checks:
Exposed secrets:
grep -r "api_key" src/
grep -r "password" src/
# Should only find references to env vars
No auth bypass:
- Try accessing protected routes without login
- Should redirect to login or return 401
Rate limiting works:
- Hit API endpoint 100 times quickly
- Should get 429 error
Success Looks Like
✅ No secrets in code (all in .env)
✅ Can't access protected routes without auth
✅ Passwords hashed, never stored plain text
✅ Rate limiting prevents abuse
✅ HTTPS enforced in production
✅ Input validated on server side
