WordPress security is mandatory. Every month, I troubleshoot several compromised sites that could have avoided the worst with basic measures.
1. Strong authentication
Enable 2FA. Limit login attempts. Ban suspicious IPs.
2. File hardening
Disable file editing in wp-admin. Protect wp-config.php. 755/644 permissions.
3. Updates
Enable minor auto-updates. Audit plugins monthly.
4. WAF & monitoring
Free Cloudflare. Wordfence or Sucuri for malware scanning.
5. Backups
External daily backups. Quarterly restore tests.
