Discussion (NIST Supplemental Guidance)

In certain situations, such as during events that are defined in contingency plans, a manual override capability for input validation may be needed. Manual overrides are used only in limited circumstances and with the inputs defined 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 SI-10(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. authorized individuals who can use the manual override capability are defined;
  2. a manual override capability for the validation of <SI-10_ODP information inputs> is provided;
  3. the use of the manual override capability is restricted to only <SI-10(01)_ODP authorized individuals>;
  4. the use of the manual override capability is audited.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; access control policy and procedures; separation of duties policy and procedures; procedures addressing information input validation; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel responsible for information input validation; organizational personnel with information security responsibilities; system/network administrators; system developer].

Test

[SELECT FROM: Organizational processes for the use of a manual override capability; mechanisms supporting and/or implementing a manual override capability for input validation; mechanisms supporting and/or implementing auditing of the use of a manual override capability].

Overlays

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)

HIGH

  • Base control: Included (matches standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-10(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.
