xSI

xSI, or cross-Site Scripting Interception, refers to a security mechanism or process aimed at detecting and preventing cross-site scripting (XSS) attacks in web applications. XSS attacks involve an attacker injecting malicious scripts into webpages viewed by users, potentially compromising user data, session tokens, and overall web application security.xSI techniques can include filtering, escaping, and validating inputs on both client and server sides to ensure that any potentially harmful scripts are neutralized before being executed by the end user's browser. It can also involve monitoring the interactions between different sites and their scripts to identify abnormalities that may signal an XSS attempt.The goal of xSI is to protect web applications from being exploited through XSS vulnerabilities, maintaining the integrity and security of web traffic and user data.
