Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of job template URIs to block untrusted external or internal destinations before SSRF requests are issued.

AC-4 Information Flow Enforcement partial match
prevent

Enforces information flow rules that can deny server-initiated HTTP requests from JobManager to internal or metadata endpoints.

SC-7 Boundary Protection partial match
prevent

Boundary protection mechanisms can restrict or inspect outbound connections from the application to internal networks and cloud metadata services.

PR.PS-06 mostly match
prevents

Secure development practices directly include input validation and destination allow-listing that prevent SSRF.

DE.CM-09 partial match
prevents

Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover and record SSRF flaws in web applications.

PR.IR-01 partial match
prevents

Network segmentation and egress controls can limit the damage from successful SSRF requests.

A.5.7 Threat intelligence partial match
prevents

Operational threat data describing SSRF campaigns can be used to tighten outbound-request allow-lists and detection rules before attackers exploit them.
