Requirements NIST SOURCE

Route networked, privileged accesses through a dedicated, managed interface for purposes of access control and auditing.

Discussion (NIST Supplemental Guidance)

Privileged access provides greater accessibility to system functions, including security functions. Adversaries attempt to gain privileged access to systems through remote access to cause adverse mission or business impacts, such as by exfiltrating information or bringing down a critical system capability. Routing networked, privileged access requests through a dedicated, managed interface further restricts privileged access for increased access control and auditing.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for SC-7(15) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. networked, privileged accesses are routed through a dedicated, managed interface for purposes of access control;
  2. networked, privileged accesses are routed through a dedicated, managed interface for purposes of auditing.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing boundary protection; system design documentation; system hardware and software; system architecture; system configuration settings and associated documentation; audit logs; system security plan; other relevant documents or records].

Interview

[SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; system developer; organizational personnel with boundary protection responsibilities].

Test

[SELECT FROM: Mechanisms supporting and/or implementing the routing of networked, privileged access through dedicated, managed interfaces].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-7(15). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
