Requirements NIST SOURCE

Test intrusion-monitoring tools and mechanisms [frequency].

Discussion (NIST Supplemental Guidance)

Testing intrusion-monitoring tools and mechanisms is necessary to ensure that the tools and mechanisms are operating correctly and continue to satisfy the monitoring objectives of organizations. The frequency and depth of testing depends on the types of tools and mechanisms used by organizations and the methods of deployment.

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(9) 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. a frequency at which to test intrusion-monitoring tools and mechanisms is defined;
  2. intrusion-monitoring tools and mechanisms are tested <SI-04(09)_ODP frequency>.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing the testing of system monitoring tools and techniques; documentation providing evidence of testing intrusion-monitoring tools; 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; organizational personnel responsible for the intrusion detection system].

Test

[SELECT FROM: Organizational processes for intrusion detection and system monitoring; mechanisms supporting and/or implementing intrusion detection and system monitoring capabilities; mechanisms supporting and/or implementing the testing of intrusion-monitoring tools].

Overlays

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-4(9). 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.
