1) Keep WordPress Core, Themes & Plugins Updated

• • Enable automatic updates where appropriate (core, minor releases, trusted plugins).
  • Review and delete unused themes/plugins.
  • Install only from reputable sources (WordPress.org, vetted vendors).

2) Use Strong Authentication

• • Enforce strong, unique passwords for all users—use a password manager.
  • Turn on Two‑Factor Authentication (2FA) for admins and editors.
  • Limit login attempts and add a CAPTCHA to deter brute‑force attacks.

3) Protect Your Admin Area

• • Change the default login URL from /wp-login.php.
  • Restrict admin access by IP (where possible) or with a VPN.
  • Disable XML‑RPC if you don’t need it; otherwise, rate‑limit it.

4) Harden Your WordPress Configuration

• Disable file editing in the dashboard by adding to wp-config.php:

define('DISALLOW_FILE_EDIT', true);

• • Use strong, unique AUTH_KEY and SALT values.
  • Restrict public access to wp-config.php, .htaccess, and other sensitive files.

5) Secure Hosting & Server Setup

• • Choose a host that specializes in WordPress security and proactive patching.
  • Force HTTPS everywhere with a valid TLS/SSL certificate (HSTS recommended).
  • Keep PHP, database, and web server software current; disable unnecessary PHP functions.

6) Regular Backups & Monitoring

• • Schedule automated daily backups stored off‑site (and keep multiple restore points).
  • Test restores quarterly to verify recovery works.
  • Run a security plugin to monitor malware, file integrity, and suspicious logins.

7) Principle of Least Privilege

• • Assign the fewest permissions necessary (Editor, Author, Contributor).
  • Remove unused users immediately and audit users quarterly.
  • Use separate accounts for day‑to‑day work and administration.

8) Continuous Security Audits

• • Run regular vulnerability scans and plugin/theme audits.
  • Review server and application logs for anomalies.
  • Track advisories for WordPress core, themes, and plugins.
