Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect neutralization of script tags through targeted XSS test cases.

Input validation explicitly requires checking and neutralizing untrusted web inputs containing script-related characters before they reach a downstream renderer.

Secure engineering principles include mandatory output encoding and neutralization of HTML metacharacters to stop injection at the source.

Secure SDLC mandates input validation and output encoding that directly prevent basic XSS.

prevents

Application security requirements explicitly call for neutralization of script-related HTML tags.

prevents

Secure coding standards require proper escaping of <, >, & to block XSS.

none

Web filtering can block some reflected XSS payloads at the network edge.
