Most website attacks are automated and target common weaknesses. The good news: a few consistent practices dramatically reduce your risk.
The essentials
- HTTPS everywhere with a valid SSL/TLS certificate.
- Keep software updated — CMS core, themes, plugins and server packages.
- Strong authentication with unique passwords and two-factor login for admins.
- Least-privilege access — give users only the permissions they need.
- Automated off-site backups that are tested regularly.
- Web application firewall to block malicious traffic.
- Spam and bot protection on every form.
For custom applications
- Validate and sanitise all input on the server.
- Never store API keys or passwords in code repositories.
- Follow OWASP Top 10 guidance and schedule security reviews.
Security is not a one-time task. Build it into your maintenance routine.
