What Is a Cross-Site Scripting?
Security analysts and DevOps teams monitoring infrastructure like Nginx, Apache HTTP Server, Node.js, AWS, and WordPress must be able to quickly identify and triage these malicious log patterns to prevent data breaches.
XSS attacks inject malicious scripts into web applications.
In logs, they appear as script tags or encoded JavaScript payloads.
How to Defend Against This Threat
