Keep WordPress, Themes, and Plugins Updated
Regular updates patch security vulnerabilities and improve functionality. To update:

Implement strong, unique passwords for all user accounts. Limit user roles to the minimum necessary permissions. For example:
- Administrator: Full access
- Editor: Content management
- Author: Own content management
- Contributor: Submit content for review
- Subscriber: Read-only access
Enable Two-Factor Authentication (2FA)
2FA adds an extra layer of security by requiring a second form of verification. Plugins like Two Factor Authentication can help implement this feature.
Install a WordPress Security Plugin
Security plugins offer comprehensive protection. Popular options include:
Implement SSL/HTTPS
SSL encrypts data transferred between your site and users. Obtain an SSL certificate through your hosting provider or services like Let’s Encrypt. Update your WordPress Address and Site Address to use https://.
Choose a Secure Hosting Provider
Select a hosting provider that prioritizes security with features like:
- Regular malware scanning
- Automatic backups
- Firewall protection

Reputable hosts include SiteGround, Kinsta, and WP Engine.
Schedule Regular Backups
Regular backups ensure you can restore your site in case of issues. Plugins like UpdraftPlus and Duplicator facilitate automated backups.
Limit Login Attempts
Prevent brute-force attacks by limiting login attempts. Use plugins like Limit Login Attempts Reloaded to set thresholds and lockout durations.
Disable File Editing in WordPress Dashboard
Prevent unauthorized code changes by disabling the built-in file editor. Add the following line to your wp-config.php file:
define('DISALLOW_FILE_EDIT', true);Change the Default Login URL
Changing the default login URL can reduce automated attacks. Plugins like WPS Hide Login allow you to customize the login URL.

Routine malware scans help detect and remove threats. Utilize tools provided by security plugins or external services like Sucuri SiteCheck.
Disable Directory Listing
