Requirements NIST SOURCE

Employ minimal functionality and information storage on the following system components: [system components].

Discussion (NIST Supplemental Guidance)

The deployment of system components with minimal functionality reduces the need to secure every endpoint and may reduce the exposure of information, systems, and services to attacks. Reduced or minimal functionality includes diskless nodes and thin client technologies.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. system components to be employed with minimal functionality and information storage are defined;
  2. minimal functionality for <SC-25_ODP system components> is employed;
  3. minimal information storage on <SC-25_ODP system components> is allocated.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-25. 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.
