Requirements NIST SOURCE

Disable, when not intended for use, wireless networking capabilities embedded within system components prior to issuance and deployment.

Discussion (NIST Supplemental Guidance)

Wireless networking capabilities that are embedded within system components represent a significant potential vulnerability that can be exploited by adversaries. Disabling wireless capabilities when not needed for essential organizational missions or functions can reduce susceptibility to threats by adversaries involving wireless technologies.

Engineering Interpretation

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

No engineering interpretation has been authored for AC-18(3) 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. when not intended for use, wireless networking capabilities embedded within system components are disabled prior to issuance and deployment.

Examine

[SELECT FROM: Access control policy; procedures addressing wireless implementation and usage (including restrictions); system design documentation; 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].

Test

[SELECT FROM: Mechanisms managing the disabling of wireless networking capabilities internally embedded within system components].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for AC-18(3). 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.
