Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and neutralization of untrusted input before web page generation, blocking the reflected XSS payload at the root cause of improper neutralization.
Requires filtering of output data to remove or encode script content, preventing reflected XSS from executing in the victim's browser context.
Can enforce web-layer malicious code inspection and filtering rules that detect and block common reflected XSS patterns before they reach the plugin.
