Requirements NIST SOURCE

Implement the following additional monitoring of privileged users: [additional monitoring].

Discussion (NIST Supplemental Guidance)

Privileged users have access to more sensitive information, including security-related information, than the general user population. Access to such information means that privileged users can potentially do greater damage to systems and organizations than non-privileged users. Therefore, implementing additional monitoring on privileged users helps to ensure that organizations can identify malicious activity at the earliest possible time and take appropriate actions.

Engineering Interpretation

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

No engineering interpretation has been authored for SI-4(20) 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. additional monitoring of privileged users is defined;
  2. <SI-04(20)_ODP additional monitoring> of privileged users is implemented.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing system monitoring tools and techniques; system design documentation; system monitoring tools and techniques documentation; system configuration settings and associated documentation; system monitoring logs or records; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; organizational personnel installing, configuring, and/or maintaining the system; organizational personnel responsible for monitoring the system].

Test

[SELECT FROM: Organizational processes for system monitoring; mechanisms supporting and/or implementing a system monitoring capability].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-4(20). 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.
