Vulnerability discussion

This control applies to telecommunications services (data and voice) for primary and alternate processing and storage sites. Alternate telecommunications services reflect the continuity requirements in contingency plans to maintain essential missions/business functions despite the loss of primary telecommunications services. Organizations may specify different time periods for primary/alternate sites. Alternate telecommunications services include, for example, additional organizational or commercial ground-based circuits/lines or satellites in lieu of ground-based communications. Organizations consider factors such as availability, quality of service, and access when entering into alternate telecommunications agreements.Organizations consider the potential mission/business impact in situations where telecommunications service providers may introduce a single point of failure if services are provided over same infrastructure or to the same organizations. For Voice Video systems, contingency planning must also consider fire and emergency services (FES) requirements for life safety and Command and Control (C2) requirements mandating communications among top-level officials, especially during crisis conditions.

Check content

Review the contingency plan for the Voice Video system that addresses essential missions and business functions. Ensure the organization obtains alternate telecommunications services to reduce the likelihood of sharing a single point of failure with primary telecommunications services. If the organization does not obtain alternate telecommunications services to reduce the likelihood of sharing a single point of failure with primary telecommunications services, this is a finding.

Fix text

Develop and document a contingency plan for the Voice Video system. As part of this plan, obtain alternate telecommunications services to reduce the likelihood of sharing a single point of failure with primary telecommunications services.
