Requirements NIST SOURCE

Test alternate telecommunication services [frequency].

Discussion (NIST Supplemental Guidance)

Alternate telecommunications services testing is arranged through contractual agreements with service providers. The testing may occur in parallel with normal operations to ensure that there is no degradation in organizational missions or functions.

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-8(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. frequency at which alternate telecommunications services are tested is defined;
  2. alternate telecommunications services are tested <CP-08(05)_ODP frequency>.

Examine

[SELECT FROM: Contingency planning policy; procedures addressing alternate telecommunications services; contingency plan; evidence of testing alternate telecommunications services; alternate telecommunications service agreements; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with contingency planning, plan implementation, and testing responsibilities; alternate telecommunications service providers; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Mechanisms supporting testing alternate telecommunications services].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CP-8(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.
