What is the main purpose of the Generic Cross-Site Scripting (XSS) prevention rule?

The main purpose of the Generic Cross-Site Scripting (XSS) prevention rule is to prevent XSS attacks. These types of attacks involve malicious scripts injected into web pages that can execute in users' browsers, leading to the exposure of sensitive information, session hijacking, or other harmful actions. By implementing this rule, organizations can protect their web applications and users by automatically detecting and blocking these harmful scripts before they can cause harm.

This proactive defense measure is essential in maintaining the integrity and security of web interactions, which is increasingly important as web technologies evolve and the sophistication of cyber threats grows. In contrast to the other options, which focus on file transfers, system file access, or SQL injection attempts, the primary focus of the Generic Cross-Site Scripting prevention rule is specifically aimed at mitigating XSS vulnerabilities.
