URLScan is a popular security tool that helps protect your web server from potential harmful HTTP requests. It is an effective defense against a myriad of web-based attacks such as SQL injection, cross-site scripting (XSS), and server-directory traversal.

Key Features

  • Analyzing Requests: URLScan examines incoming HTTP requests to identify potentially malicious patterns or signs of an attack.
  • Blocking URLs: By filtering URLs with specific patterns or known bad signatures, URLScan helps protect your web server from harmful requests.
  • Customizable Rules: You can create custom rules tailored to your specific environment to provide a comprehensive security solution.
  • Logging: URLScan logs security-related events, allowing you to monitor and act on potential security threats.

Usage in Cyber Security

Some common use-cases for URLScan in the cyber security realm are:

  • Prevent SQL Injection: URLScan is capable of detecting requests that contain SQL-like patterns, helping to secure your web applications from SQL injection attacks.
  • Mitigate XSS Attacks: URLScan can be configured to deny requests with common cross-site scripting patterns or specific user-agent strings associated with known exploits.
  • Control Access to Sensitive Directories: By configuring URLScan to block access to specific directories or file types, you can reduce the risk of unauthorized access to sensitive files on your web server.
  • Monitor Suspicious Activity: Since URLScan provides detailed logs of security events, you can use this information to quickly identify and respond to potential security threats.


URLScan is an essential tool for maintaining web server security in today’s complex online environment. By implementing this tool, you can mitigate common web-based attacks and reduce the number of potential threats to your web server. Don’t forget to monitor the logs generated by URLScan regularly to stay on top of potential threats and ensure the ongoing security of your web application.
