Regularly update your website's software, including the content management system (CMS), plugins, themes, and any other third-party applications.
Ensure that your website uses HTTPS (SSL/TLS) to encrypt data transmitted between the user's browser and your web server. This helps protect sensitive information.
Implement a web application firewall (WAF) to filter and monitor HTTP traffic between a web application and the Internet. This helps protect against various web application attacks.
Regularly back up your website's data and ensure that backups are stored securely. In the event of a cyber-attack or data loss, having up-to-date backups allows you to restore your website quickly.
Implement monitoring tools to track and analyze website traffic. Set up alerts for suspicious activities or potential security incidents.
