Requirements NIST SOURCE

Test backup information [organization-defined frequency] to verify media reliability and information integrity.

Discussion (NIST Supplemental Guidance)

Organizations need assurance that backup information can be reliably retrieved. Reliability pertains to the systems and system components where the backup information is stored, the operations used to retrieve the information, and the integrity of the information being retrieved. Independent and specialized tests can be used for each of the aspects of reliability. For example, decrypting and transporting (or transmitting) a random sample of backup files from the alternate storage or backup site and comparing the information to the same information at the primary processing site can provide such assurance.

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(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. frequency at which to test backup information for media reliability is defined;
  2. frequency at which to test backup information for information integrity is defined;
  3. backup information is tested <CP-09(01)_ODP[01] frequency> to verify media reliability;
  4. backup information is tested <CP-09(01)_ODP[02] frequency> to verify information integrity.

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 information security responsibilities].

Test

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

Overlays

Showing the OT/ICS overlay for the parent control CP-9 — see the CP-9(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.

STIGs & CCIs

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