Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces validation of untrusted URL/input parameters that an attacker would supply to trigger the SSRF request.

prevent

Restricts outbound network connections from the server, blocking the forged requests that constitute the SSRF vector.

prevent

Enforces information-flow rules that can deny the server the ability to reach arbitrary external or internal destinations supplied by the attacker.
