What other measures can I take to improve my WordPress website's security?

In addition to keeping your WordPress plugins up-to-date, there are several other measures you can take to enhance your website's security:

1. Use strong, unique passwords for all user accounts and enable two-factor authentication.
2. Regularly update your WordPress core and themes to ensure you have the latest security patches.
3. Limit user access privileges to the minimum required for each user's role.
4. Implement a web application firewall (WAF) to block common attacks and filter malicious traffic.
5. Regularly back up your website files and database to minimize potential data loss in case of a security breach.

By implementing these security best practices, you can create a multi-layered defense system that helps protect your website from various threats.
