Requirements NIST SOURCE

Use a sample of backup information in the restoration of selected system functions as part of contingency plan testing.

Discussion (NIST Supplemental Guidance)

Organizations need assurance that system functions can be restored correctly and can support established organizational missions. To ensure that the selected system functions are thoroughly exercised during contingency plan testing, a sample of backup information is retrieved to determine whether the functions are operating as intended. Organizations can determine the sample size for the functions and backup information based on the level of assurance needed.

Engineering Interpretation

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

No engineering interpretation has been authored for CP-9(2) 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. a sample of backup information in the restoration of selected system functions is used as part of contingency plan testing.

Examine

[SELECT FROM: Contingency planning policy; procedures addressing system backup; contingency plan; system backup test results; contingency plan test documentation; contingency plan test results; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system backup responsibilities; organizational personnel with contingency planning/contingency plan testing responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational processes for conducting system backups; mechanisms supporting and/or implementing system backups].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CP-9(2). 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.
