Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Validates information inputs to prevent SSRF exploitation by rejecting malformed or unauthorized URLs that could trigger unauthorized server-side requests leading to privilege escalation.

prevent

Enforces information flow control policies to block unauthorized outbound requests from the Azure OpenAI service initiated via SSRF.

prevent

Monitors and controls communications at system boundaries to restrict SSRF attempts that could enable privilege escalation within the Azure OpenAI environment.
