Security Best Practices
✅ Do:
- • Use environment variables for secrets in production
- • Encode sensitive values before committing to version control
- • Use secret management systems (AWS Secrets Manager, etc.)
- • Rotate secrets regularly
- • Validate environment variables at application startup
❌ Don't:
- • Commit plain-text secrets to repositories
- • Log environment variables containing secrets
- • Share encoded secrets without proper access control
- • Use weak encoding for production secrets
- • Forget to sanitize environment variables in error messages
