CP-8 (02)—Telecommunications Services | Single Points of Failure
Moderate
High
>Control Description
Obtain alternate telecommunications services to reduce the likelihood of sharing a single point of failure with primary telecommunications services.
>FedRAMP Baseline Requirements
No FedRAMP-specific parameter values or requirements for this baseline.
>Discussion
In certain circumstances, telecommunications service providers or services may share the same physical lines, which increases the vulnerability of a single failure point. It is important to have provider transparency for the actual physical transmission capability for telecommunication services.
