Discussion (NIST Supplemental Guidance)

In many organizations, systems support multiple mission and business functions. Limiting privileges to change system components with respect to operational systems is necessary because changes to a system component may have far-reaching effects on mission and business processes supported by the system. The relationships between systems and mission/business processes are, in some cases, unknown to developers. System-related information includes operational procedures.

Engineering Interpretation

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

No engineering interpretation has been authored for CM-5(5) 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. frequency at which to review privileges is defined;
  2. frequency at which to reevaluate privileges is defined;
  3. privileges to change system components within a production or operational environment are limited;
  4. privileges to change system-related information within a production or operational environment are limited;
  5. privileges are reviewed <CM-05(05)_ODP[01] frequency>;
  6. privileges are reevaluated <CM-05(05)_ODP[02] frequency>.

STIGs & CCIs

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