Test the contingency plan at the alternate processing site:

Discussion (NIST Supplemental Guidance)

Conditions at the alternate processing site may be significantly different than the conditions at the primary site. Having the opportunity to visit the alternate site and experience the actual capabilities available at the site can provide valuable information on potential vulnerabilities that could affect essential organizational mission and business functions. The on-site visit can also provide an opportunity to refine the contingency plan to address the vulnerabilities discovered during testing.

Implementation Guidance

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-4(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. the contingency plan is tested at the alternate processing site to familiarize contingency personnel with the facility and available resources;
  2. the contingency plan is tested at the alternate processing site to evaluate the capabilities of the alternate processing site to support contingency operations.

Examine

[SELECT FROM: Contingency planning policy; procedures addressing contingency plan testing; contingency plan; contingency plan test documentation; contingency plan test results; alternate processing site agreements; service-level agreements; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with contingency planning and plan implementation responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational processes for contingency plan testing; mechanisms supporting the contingency plan and/or contingency plan testing].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CP-4(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.
