Mitigating Controls (NIST 800-53 r5) AI

IA-3 Device Identification and Authentication good match

IA-3 mandates device identification and authentication prior to establishing communications, addressing the non-endpoint actor risk.

SC-23 Session Authenticity good match

SC-23 enforces session authenticity protections that verify both endpoints and prevent channel manipulation by outsiders.

SC-11 Trusted Path good match

SC-11 provides an isolated trusted path that cryptographically or physically assures the identities of the two endpoints.

SC-8 Transmission Confidentiality and Integrity good match

SC-8 directly requires cryptographic or equivalent mechanisms to protect the integrity (and confidentiality) of transmitted data, stopping non-endpoint interference.

AC-17 Remote Access partial match

AC-17 requires documented usage restrictions and secure configuration for remote access channels, reducing exposure to non-endpoint actors.

IA-2 Identification and Authentication (Organizational Users) partial match

IA-2 requires unique identification and authentication of organizational users before any channel use, blocking unauthenticated endpoint access.

PR.AA-03 mostly match
prevents

Enforces authentication of endpoints, mitigating non-endpoint access but not channel integrity itself.

PR.DS-02 mostly match
prevents

Directly protects integrity of data-in-transit, addressing channel integrity but not endpoint identity verification.

PR.AA-04 partial match
prevents

Supports verification of identity assertions exchanged over the channel.

PR.IR-01 partial match
prevents

Reduces unauthorized network access that could exploit an unprotected channel.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography mostly match
prevents

Cryptography provides channel integrity and can support endpoint authentication.

A.8.5 Secure authentication mostly match
prevents

Secure authentication mechanisms verify actor identity at both ends of the channel.

A.5.14 Information transfer partial match
prevents

Information transfer policies address secure exchange but are high-level and not technical.

A.8.20 Networks security partial match
mitigates

Network security controls directly address channel integrity and endpoint authentication.

A.8.21 Security of network services partial match
mitigates

Security of network services includes measures to verify endpoints and protect channel integrity.

A.8.22 Segregation of networks partial match
mitigates

Network segregation reduces exposure but does not verify endpoint identity or channel integrity.
