Which tool would be the least effective in preventing web application vulnerabilities?

  1. Burp Suite

  2. Wireshark

  3. Medusa

  4. HashCat

The correct answer is: Wireshark

Wireshark is primarily a network protocol analyzer, which means its main function is to capture and display packet data from a network. While it is an essential tool for network monitoring and troubleshooting, it does not focus on web application security directly. Its capabilities are geared towards analysis rather than prevention of web application vulnerabilities. It allows users to inspect traffic to identify issues but does not provide active measures to secure or defend against vulnerabilities in web applications. On the other hand, Burp Suite is explicitly designed for web application security testing and can actively assist in identifying and exploiting vulnerabilities. Medusa is a password-cracking tool that can help assess the security of authentication mechanisms, and HashCat is a powerful hash-cracking tool that deals with password security. Both Medusa and HashCat contribute to identifying vulnerabilities related to user authentication and password strength. Thus, in the context of preventing web application vulnerabilities, Wireshark is, indeed, the least effective of the tools listed.
