Requirements NIST SOURCE

Perform an integrity check of [organization-defined software, firmware, and information][one of: at startup; at; ].

Discussion (NIST Supplemental Guidance)

Security-relevant events include the identification of new threats to which organizational systems are susceptible and the installation of new hardware, software, or firmware. Transitional states include system startup, restart, shutdown, and abort.

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-7(1) 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. software on which an integrity check is to be performed is defined;
  2. one or more of the following PARAMETER VALUES is/are selected: {at startup; at <SI-07(01)_ODP[03] transitional states or security-relevant events>; <SI-07(01)_ODP[04] frequency>};
  3. transitional states or security-relevant events requiring integrity checks (on software) are defined (if selected);
  4. frequency with which to perform an integrity check (on software) is defined (if selected);
  5. firmware on which an integrity check is to be performed is defined;
  6. one or more of the following PARAMETER VALUES is/are selected: {at startup; at <SI-07(01)_ODP[07] transitional states or security-relevant events>; <SI-07(01)_ODP[08] frequency>};
  7. transitional states or security-relevant events requiring integrity checks (on firmware) are defined (if selected);
  8. frequency with which to perform an integrity check (on firmware) is defined (if selected);
  9. information on which an integrity check is to be performed is defined;
  10. one or more of the following PARAMETER VALUES is/are selected: {at startup; at <SI-07(01)_ODP[11] transitional states or security-relevant events>; <SI-07(01)_ODP[12] frequency>};
  11. transitional states or security-relevant events requiring integrity checks (of information) are defined (if selected);
  12. frequency with which to perform an integrity check (of information) is defined (if selected);
  13. an integrity check of <SI-07(01)_ODP[01] software> is performed <SI-07(01)_ODP[02] SELECTED PARAMETER VALUES>;
  14. an integrity check of <SI-07(01)_ODP[05] firmware> is performed <SI-07(01)_ODP[06] SELECTED PARAMETER VALUES>;
  15. an integrity check of <SI-07(01)_ODP[09] information> is performed <SI-07(01)_ODP[10] SELECTED PARAMETER VALUES>.

Examine

Overlays

Showing the OT/ICS overlay for the parent control SI-7 — see the SI-7(1) entries within each baseline below.

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

LOW

Not applicable at this tier.

MODERATE

  • Base control: Included (matches standard baseline)
  • Included: (1) (7)

HIGH

  • Base control: Included (matches standard baseline)
  • Included: (1) (2) (5) (7) (15)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-7(1). 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.
