What is the primary function of UrlScan?

• A. A password manager
• B. A firewall for all ports
• C. A security tool that restricts the types of HTTP requests
• D. A vulnerability scanner for FTP only

Answer: (C)

UrlScan acts as an application-layer security filter that sits in front of the web server and tightens what HTTP requests are allowed. It enforces configurable rules on the requests, such as which URL patterns, query strings, HTTP verbs, and headers can be used, and it blocks requests that match dangerous patterns or contain suspicious characters. By doing so, it reduces the attack surface and helps prevent common web server attacks like directory traversal or method abuse. It’s not a password manager, not a network firewall for all ports, and not a vulnerability scanner for FTP, so its primary role is to restrict and validate HTTP requests reaching the server.
