Cross-Site Scripting (XSS) Protection

Question 1

Juniper’s Web Application Firewall is designed to detect and block XSS attacks in web traffic. It analyzes HTTP/HTTPS requests and responses, looking for malicious scripts and patterns commonly associated with XSS. It can also perform input validation and sanitize user inputs to prevent script execution.

Answer 1

Web Application Firewall (WAF)

Question 2

Juniper Firewalls equipped with content filtering and application control features can block access to websites and applications known for hosting malicious scripts. This helps prevent users from interacting with potentially harmful content.

Answer 2

Content Filtering and Application Control

Question 3

Juniper Firewalls can employ regex pattern matching to identify and block XSS attempts in HTTP requests. By detecting patterns commonly used in XSS payloads, the firewall can prevent the execution of malicious scripts.

Answer 3

Regular Expression (Regex) Pattern Matching

Question 4

Juniper Firewalls can inspect HTTP headers and content for signs of malicious scripts. They can strip or modify suspicious content to prevent script execution and protect web applications from XSS attacks.

Answer 4

HTTP Header and Content Inspection

Question 5

While not a specific firewall feature, Juniper promotes secure coding practices for web application development. Educating developers about input validation, output encoding, and other secure coding techniques helps reduce the risk of XSS vulnerabilities.
