Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-3 directly requires enforcement of authorizations for access to resources such as URLs, scripts, and files, structurally preventing forced browsing.

AC-24 requires that access-control decisions be applied to every request, addressing the missing enforcement on restricted URLs.

AC-6 requires restricting authorizations to the minimum needed, reducing the set of resources that must be protected against direct requests.

PR.AA-05 full match
prevents

Directly requires policy-driven definition, enforcement, and review of authorizations on resources such as URLs.

PR.IR-01 mostly match
prevents

Protects environments from unauthorized logical access, which includes preventing direct requests to restricted paths.

finds

Security testing can detect forced-browsing flaws, but the control itself does not prevent them in production.

prevents

Information access restriction implements the technical enforcement that directly blocks unauthorized direct requests.

prevents

Access control policy directly requires authorization checks on all resources, preventing forced browsing.

degrades

Managing access rights ensures every URL/script/file is explicitly authorized, mitigating direct request attacks.

degrades

Privileged access rights control enforces least-privilege checks on restricted endpoints.

prevents

Secure SDLC can include authorization design, yet the control itself does not guarantee runtime enforcement.
