Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces access decisions on the REST API, requiring proper verification of communication source before allowing actions.
Controls and monitors all external network traffic to the REST API at system boundaries, blocking improperly sourced channels.
Mandates authorization, encryption, and source verification for all remote REST API connections to prevent bypasses.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Authentication of users/services/hardware directly enforces source verification for communication channels.
Verifying identity assertions prevents spoofed channel origins but does not cover all channel-establishment scenarios.
Network protections reduce unauthorized channel usage but do not specifically require origin verification at channel setup.

Secure authentication mechanisms verify the identity and origin of communication channel initiators.
Network security controls enforce source verification and channel authentication for incoming communications.
Security of network services includes validating the origin of service requests and connections.
Network segregation limits exposure but does not directly verify source of individual channels.
Cryptography can support channel authentication but does not inherently verify source without proper implementation.
Application security requirements may specify origin checks but do not mandate them.
