Requirements NIST SOURCE

Provide [one of: physical; logical] disconnect of collaborative computing devices in a manner that supports ease of use.

Discussion (NIST Supplemental Guidance)

Failing to disconnect from collaborative computing devices can result in subsequent compromises of organizational information. Providing easy methods to disconnect from such devices after a collaborative computing session ensures that participants carry out the disconnect activity without having to go through complex and tedious procedures. Disconnect from collaborative computing devices can be manual or automatic.

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-15(1) 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. one or more of the following PARAMETER VALUES is/are selected: {physical; logical};
  2. the <SC-15(01)_ODP SELECTED PARAMETER VALUES> disconnect of collaborative computing devices is/are provided in a manner that supports ease of use.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing collaborative computing; access control policy and procedures; 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; system developer; organizational personnel with responsibilities for managing collaborative computing devices].

Test

[SELECT FROM: Mechanisms supporting and/or implementing the physical disconnect of collaborative computing devices].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-15(1). 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.
