Ensuring the security of your Content Management System (CMS) is vital to protect your website from potential threats. Start by keeping your CMS and all plugins up to date, as updates often include security patches. Use strong, unique passwords for all user accounts and consider implementing two-factor authentication for added security. Regularly back up your website to prevent data loss in case of an attack. Additionally, monitor user activity and restrict access to sensitive areas of your CMS. By following these best practices, you can significantly reduce the risk of security breaches and maintain the integrity of your website.
