1. Never commit secrets

   • Use .env files (git-ignored)
   • Use environment variables
   • Use secret management services

2. Validate all input

   • Backend validation required
   • Frontend validation for UX
   • Sanitize before database operations

3. Use parameterized queries

   • Always use ORM methods
   • Never concatenate SQL strings
   • Use prepared statements

4. Handle errors securely

   • Don't expose stack traces
   • Log errors securely
   • Return generic error messages

5. Keep dependencies updated
