Requirements NIST SOURCE

Take system components out of service by transferring component responsibilities to substitute components no later than [fraction or percentage] of mean time to failure.

Discussion (NIST Supplemental Guidance)

Transferring primary system component responsibilities to other substitute components prior to primary component failure is important to reduce the risk of degraded or debilitated mission or business functions. Making such transfers based on a percentage of mean time to failure allows organizations to be proactive based on their risk tolerance. However, the premature replacement of system components can result in the increased cost of system operations.

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(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. the fraction or percentage of mean time to failure within which to transfer the responsibilities of a system component to a substitute component is defined;
  2. system components are taken out of service by transferring component responsibilities to substitute components no later than <SI-13(01)_ODP fraction or percentage> of mean time to failure.

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; system audit records; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Organizational processes for managing MTTF; automated mechanisms supporting and/or implementing the transfer of component responsibilities to substitute components].

STIGs & CCIs

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