Website security depends on multiple layers: application, accounts, server, DNS, backups and monitoring. The most effective measures are those applied consistently, not only after an incident occurs.
1. Use HTTPS everywhere
Install a valid SSL certificate and redirect all HTTP requests to HTTPS. This encrypts the data transmitted between the visitor and the server.
2. Keep the platform and extensions updated
Outdated CMS software, modules, themes and libraries may contain known vulnerabilities. Apply updates in a controlled way and check the website after each change.
3. Use unique passwords and two-factor authentication
Administrative accounts should be protected with long, unique passwords and, where possible, multi-factor authentication.
4. Limit user permissions
Each account should have only the permissions it needs. Remove old accounts and avoid using the administrator account for routine activities.
5. Create automatic backups
Keep regular copies of files and databases, ideally in a separate location as well. Test restoration, not just the existence of backups.
6. Protect forms and authentication
Use CSRF protection, server-side validation, CAPTCHA where justified, and rate-limit repeated login attempts.
7. Configure a firewall and traffic filtering
A web application firewall can block a significant portion of malicious requests before they reach the application.
8. Monitor files and logs
Unexpected changes, repeated errors and suspicious logins may indicate an incident. Monitoring helps identify problems quickly.
9. Secure hosting and DNS
Protect hosting and registrar accounts, enable multi-factor authentication and restrict DNS access to authorized people only.
10. Prepare an incident response plan
Define in advance who responds, how the issue is isolated, how the service is restored and how data integrity is checked after an incident.
Conclusion
Security is an ongoing process. Updates, backups, access control and monitoring significantly reduce risk and recovery time.
