Requirements NIST SOURCE

Determine information about the system that is discoverable and take [corrective actions].

Discussion (NIST Supplemental Guidance)

Discoverable information includes information that adversaries could obtain without compromising or breaching the system, such as by collecting information that the system is exposing or by conducting extensive web searches. Corrective actions include notifying appropriate organizational personnel, removing designated information, or changing the system to make the designated information less relevant or attractive to adversaries. This enhancement excludes intentionally discoverable information that may be part of a decoy capability (e.g., honeypots, honeynets, or deception nets) deployed by the organization.

Engineering Interpretation

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

No engineering interpretation has been authored for RA-5(4) 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. corrective actions to be taken if information about the system is discoverable are defined;
  2. information about the system is discoverable;
  3. <RA-05(04)_ODP corrective actions> are taken when information about the system is confirmed as discoverable.

Examine

Interview

[SELECT FROM: Organizational personnel with vulnerability scanning and/or penetration testing responsibilities; organizational personnel with vulnerability scan analysis responsibilities; organizational personnel responsible for risk response; organizational personnel responsible for incident management and response; organizational personnel with security responsibilities].

Test

[SELECT FROM: Organizational processes for vulnerability scanning; organizational processes for risk response; organizational processes for incident management and response; mechanisms/tools supporting and/or implementing vulnerability scanning; mechanisms supporting and/or implementing risk response; mechanisms supporting and/or implementing incident management and response].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for RA-5(4). 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.
