Requirements NIST SOURCE

Provide [one of: real-time; near real-time][failover capability] for the system.

Discussion (NIST Supplemental Guidance)

Failover refers to the automatic switchover to an alternate system upon the failure of the primary system. Failover capability includes incorporating mirrored system operations at alternate processing sites or periodic data mirroring at regular intervals defined by the recovery time periods of organizations.

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-13(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. one of the following PARAMETER VALUES is selected: {real-time; near real-time};
  2. a failover capability for the system has been defined;
  3. <SI-13(05)_ODP[01] SELECTED PARAMETER VALUE> <SI-13(05)_ODP[02] failover capability> is provided for the system.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing predictable failure prevention; system design documentation; system configuration settings and associated documentation; documentation describing the failover capability provided for the system; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel responsible for the failover capability; organizational personnel with information security responsibilities; system/network administrators; organizational personnel with contingency planning responsibilities].

Test

[SELECT FROM: Organizational processes for managing the failover capability; automated mechanisms supporting and/or implementing the failover 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

Not applicable at this tier.

HIGH

  • Base control: Added (beyond standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-13(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.
