Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of user-supplied information inputs like payment amounts, preventing external control of assumed-immutable web parameters via crafted requests.

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Limits and authorizes specific actions performable without identification or authentication, preventing unauthenticated attackers from modifying payment amounts.

IA-8 Identification and Authentication (Non-organizational Users) good match

prevent

Mandates identification and authentication for non-organizational users accessing the public payment portal, blocking unauthenticated crafted requests.
