Requirements NIST SOURCE

Support the management of system accounts using [automated mechanisms].

Discussion (NIST Supplemental Guidance)

Automated system account management includes using automated mechanisms to create, enable, modify, disable, and remove accounts; notify account managers when an account is created, enabled, modified, disabled, or removed, or when users are terminated or transferred; monitor system account usage; and report atypical system account usage. Automated mechanisms can include internal system functions and email, telephonic, and text messaging notifications.

Implementation Guidance

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-2(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. automated mechanisms used to support the management of system accounts are defined;
  2. the management of system accounts is supported using <AC-02(01)_ODP automated mechanisms>.

Examine

[SELECT FROM: Access control policy; procedures for addressing account management; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with account management responsibilities; system/network administrators; organizational personnel with information security with information security responsibilities; system developers].

Test

[SELECT FROM: Automated mechanisms for implementing account management functions].

Overlays

Showing the OT/ICS overlay for the parent control AC-2 — see the AC-2(1) 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.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for AC-2(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.
