Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and neutralization of untrusted input before it is used in web page generation, blocking the reflected XSS payload in ListingHub.

SI-15 Information Output Filtering good match
prevent

Mandates filtering or encoding of information sent to users, preventing malicious scripts from being reflected and executed in the browser.

SI-3 Malicious Code Protection partial match
preventdetect

Provides mechanisms to detect and block malicious code (scripts) delivered via web requests or responses, offering secondary protection against the XSS vector.
