Additionally, customers should ensure that all web applications are configured correctly and that all user input is validated before being processed. Furthermore, customers should regularly monitor their systems for any suspicious activity.

  It is important to note that directory traversal attacks can be difficult to detect as they often occur without any visible signs. Therefore, it is important to regularly monitor your system for any suspicious activity and take appropriate measures if any are detected.
