Requirements NIST SOURCE

Determine if system components have applicable security-relevant software and firmware updates installed using [automated mechanisms][frequency].

Discussion (NIST Supplemental Guidance)

Automated mechanisms can track and determine the status of known flaws for system components.

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-2(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 determine if applicable security-relevant software and firmware updates are installed on system components are defined;
  2. the frequency at which to determine if applicable security-relevant software and firmware updates are installed on system components is defined;
  3. system components have applicable security-relevant software and firmware updates installed <SI-02(02)_ODP[02] frequency> using <SI-02(02)_ODP[01] automated mechanisms>.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing flaw remediation; automated mechanisms supporting centralized management of flaw remediation; 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; organizational personnel installing, configuring, and/or maintaining the system; organizational personnel responsible for flaw remediation].

Test

[SELECT FROM: Automated mechanisms used to determine the state of system components with regard to flaw remediation].

Overlays

STIGs & CCIs

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