Website Security Essentials

A hacked website damages trust, rankings and revenue. Most attacks exploit basic weaknesses that are easy to prevent.

1. Keep everything updated

Outdated CMS cores, plugins and themes are the most common entry point. Apply updates regularly and test them on a staging site first.

2. Back up reliably

Automated, off-site backups with tested restores. A backup you have never restored is only a hope.

3. Control access

  • Strong, unique passwords and two-factor authentication.
  • Role-based permissions: no one gets more access than they need.
  • Remove accounts that are no longer used.

Other essentials

  • HTTPS on every page.
  • A web application firewall.
  • Malware scanning and uptime monitoring.
  • Secure hosting with isolated environments.
  • Limited login attempts.

Plan for incidents

Document what happens if a site is compromised: who is notified, how it is restored and how the client is informed.

Data protection

Sites that collect personal data must protect it in line with GDPR.

Ongoing care

oceanone's website maintenance plans include updates, backups and security monitoring.
