Requirements NIST SOURCE

Provide a logout capability for user-initiated communications sessions whenever authentication is used to gain access to [information resources].

Discussion (NIST Supplemental Guidance)

Information resources to which users gain access via authentication include local workstations, databases, and password-protected websites or web-based services.

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-12(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. information resources for which a logout capability for user-initiated communications sessions is required are defined;
  2. a logout capability is provided for user-initiated communications sessions whenever authentication is used to gain access to <AC-12(01)_ODP information resources>.

Examine

[SELECT FROM: Access control policy; procedures addressing session termination; user logout messages; 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 developers].

Test

[SELECT FROM: System session termination mechanisms; logout capabilities for user-initiated communications sessions].

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.

LOW

Not applicable at this tier.

MODERATE

  • Base control: Included (matches standard baseline)

HIGH

  • Base control: Included (matches standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for AC-12(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.
