XSS

Attacks

Acronym for Cross-Site Scripting—injecting malicious scripts into web pages.

XSS stands for Cross-Site Scripting. See 'Cross-Site Scripting' for the full definition. The abbreviation uses 'X' rather than 'C' to avoid confusion with CSS (Cascading Style Sheets).

Why It Matters

The DSC Perspective:

XSS vulnerabilities are common in web applications. Regular security testing and secure development practices are essential. If you develop or manage web applications, XSS should be on your vulnerability checklist.
