What is XSS prevention?

The following suggestions can help safeguard your users against XSS attacks: Sanitize user input: Validate to catch potentially malicious user-provided input. Encode output to prevent potentially malicious user-provided data from triggering automatic load-and-execute behavior by a browser.

What is stored XSS and how can you prevent it?

This type of exploit, known as Stored XSS, is particularly insidious because the indirection caused by the data store makes it more difficult to identify the threat and increases the possibility that the attack will affect multiple users. XSS got its start in this form with websites that offered a “guestbook” to visitors.

How to prevent XSS attacks with OWASP?

The primary defenses against XSS are described in the OWASP XSS Prevention Cheat Sheet. Also, it’s crucial that you turn off HTTP TRACE support on all web servers. An attacker can steal cookie data via Javascript even when document.cookie is disabled or not supported by the client.
