Requirements NIST SOURCE

Analyze [systems or system components] supporting mission essential services or functions to ensure that the information resources are being used consistent with their intended purpose.

Discussion (NIST Supplemental Guidance)

Systems are designed to support a specific mission or business function. However, over time, systems and system components may be used to support services and functions that are outside of the scope of the intended mission or business functions. This can result in exposing information resources to unintended environments and uses that can significantly increase threat exposure. In doing so, the systems are more vulnerable to compromise, which can ultimately impact the services and functions for which they were intended. This is especially impactful for mission-essential services and functions. By analyzing resource use, organizations can identify such potential exposures.

No engineering interpretation has been authored for PM-32 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. the systems or system components supporting mission-essential services or functions are defined;
  2. <PM-32_ODP systems or system components> supporting mission-essential services or functions are analyzed to ensure that the information resources are being used in a manner that is consistent with their intended purpose.

Examine

[SELECT FROM: Information security program plan; privacy program plan; list of essential services and functions; organizational analysis of information resources; risk management strategy; other relevant documents or records.].

Interview

[SELECT FROM: Organizational personnel with information security, privacy, and supply chain risk management program responsibilities].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PM-32. 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.
