Update regularly Updates patch known security flaws. Never ignore them. - CMS and frameworks - Plugins and extensions - Server and PHP/Node.js ## 3. Validate every user input Never trust the data submitted by users. ```php $email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL); ``` ## 4. Protect against SQL injection Always use prepared statements: ```php $stmt = $pdo->prepare("SELECT * FROM users WHERE email = ?"); $stmt->execute([$email]); ``` ## 5. Enforce a strong password policy - Minimum 12 characters - A mix of uppercase, lowercase, numbers, and symbols - Checks against compromised passwords ## 6. Enable two-factor authentication 2FA adds an extra layer of security even if the password is compromised. ## 7. Configure security headers ``` Content-Security-Policy: default-src 'self' X-Frame-Options: DENY X-Content-Type-Options: nosniff ``` ## 8. Back up regularly - Automated daily backups - Off-site storage - Regular restore tests ## 9. Monitor suspicious activity Set up alerts for: - Failed login attempts - Changes to critical files - Abnormal traffic ## 10. Train your team Security is everyone's responsibility. Regularly educate your team on best practices. --- Web security is an ongoing process.
