CP-8 (2) - Single Points of Failure
Control requirements
CP-8 (2) - 0
Obtain alternate telecommunications services to reduce the likelihood of sharing a single point of failure with primary telecommunications services.
NIST supplemental guidance
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.
