Requirements NIST SOURCE

Use [automated mechanisms] to [one of: notify of individual termination actions; disable access to system resources].

Discussion (NIST Supplemental Guidance)

In organizations with many employees, not all personnel who need to know about termination actions receive the appropriate notifications, or if such notifications are received, they may not occur in a timely manner. Automated mechanisms can be used to send automatic alerts or notifications to organizational personnel or roles when individuals are terminated. Such automatic alerts or notifications can be conveyed in a variety of ways, including via telephone, electronic mail, text message, or websites. Automated mechanisms can also be employed to quickly and thoroughly disable access to system resources after an employee is terminated.

Engineering Interpretation

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

No engineering interpretation has been authored for PS-4(2) 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 to notify personnel or roles of individual termination actions and/or to disable access to system resources are defined;
  2. one or more of the following PARAMETER VALUES is/are selected: {notify <PS-04(02)_ODP[03] personnel or roles> of individual termination actions; disable access to system resources};
  3. personnel or roles to be notified upon termination of an individual is/are defined (if selected);
  4. <PS-04(02)_ODP[01] automated mechanisms> are used to <PS-04(02)_ODP[02] SELECTED PARAMETER VALUES>.

Examine

[SELECT FROM: Personnel security policy; procedures addressing personnel termination; system design documentation; system configuration settings and associated documentation; records of personnel termination actions; automated notifications of employee terminations; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with personnel security responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational processes for personnel termination; automated mechanisms supporting and/or implementing personnel termination notifications].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PS-4(2). 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.
