Requirements NIST SOURCE

Isolate [information security tools, mechanisms, and support components] from other internal system components by implementing physically separate subnetworks with managed interfaces to other components of the system.

Discussion (NIST Supplemental Guidance)

Physically separate subnetworks with managed interfaces are useful in isolating computer network defenses from critical operational processing networks to prevent adversaries from discovering the analysis and forensics techniques employed by organizations.

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(13) 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

information security tools, mechanisms, and support components to be isolated from other internal system components are defined;
<SC-07(13)_ODP information security tools, mechanisms, and support components> are isolated from other internal system components by implementing physically separate subnetworks with managed interfaces to other components of the system.

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; list of security tools and support components to be isolated from other internal system components; system audit records; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Mechanisms supporting and/or implementing the isolation of information security tools, mechanisms, and support components].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-7(13). 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.
