CP-8(3) Telecommunications Services | Separation of Primary and Alternate Providers
Obtain alternate telecommunications services from providers that are separated from primary service providers to reduce susceptibility to the same threats.
Source: NIST SP 800-53 Rev 5, CP-8(3). The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-53 Rev 5 in the compliance library.
Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Alternate telecommunications service is purchased from the same provider or its reseller as the primary service
