Requirements NIST SOURCE

Implement [host-based boundary protection mechanisms] at [system components].

Discussion (NIST Supplemental Guidance)

Host-based boundary protection mechanisms include host-based firewalls. System components that employ host-based boundary protection mechanisms include servers, workstations, notebook computers, and mobile devices.

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(12) 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. host-based boundary protection mechanisms to be implemented are defined;
  2. system components where host-based boundary protection mechanisms are to be implemented are defined;
  3. <SC-07(12)_ODP[01] host-based boundary protection mechanisms> are implemented at <SC-07(12)_ODP[02] system components>.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing boundary protection; system design documentation; boundary protection hardware and software; system configuration settings and associated documentation; 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; system users].

Test

[SELECT FROM: Mechanisms implementing host-based boundary protection capabilities].

Overlays

Showing the OT/ICS overlay for the parent control SC-7 — see the SC-7(12) entries within each baseline below.

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

  • Base control: Included (matches standard baseline)
  • Added: (28) (29)

MODERATE

  • Base control: Included (matches standard baseline)
  • Included: (3) (4) (5) (7) (8)
  • Added: (18) (28) (29)

HIGH

  • Base control: Included (matches standard baseline)
  • Included: (3) (4) (5) (7) (8) (18) (21)
  • Added: (28) (29)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-7(12). 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.
