The organization must provide an uninterruptible power supply (UPS) to ensure continuous power for Assured Service (AS) DISN Voice Precedence users and fire and emergency services (FES) communications for Voice Video system users and transition to long-term alternate power in the event of a primary power source loss.

Vulnerability discussion

Power systems rely on multiple tiers of defense for providing continuous power to sites and systems. Commercial power may be supplemented by UPS, generators, or other means. Power must be distributed to the network infrastructure, endpoints, servers, and other network devices to ensure constant delivery of services. Voice Video systems must be designed and implemented to ensure fire and emergency services (FES) are always available.Voice Video endpoint users require different levels of capability depending on DISN Voice Precedence needs. Flash/Flash Override users must have eight hours of continuous backup power at all times. Immediate/Priority users must have two hours of continuous backup power. Routine and lower users do not require backup power, except to provide necessary FES. The UPS must provide power for the LAN infrastructure, WAN boundary, Voice Video infrastructure, and Voice Video endpoints.

Review the Voice Video system security plan (SSP) for design criteria for the physical environment of the Voice Video system. Ensure the UPS provides continuous power to support DISN Voice Precedence users and FES communications. Verify the Voice Video system transitions to long-term alternate power in the event of a primary power source loss. Confirm the LAN Infrastructure, WAN boundary, Voice Video infrastructure, and Voice Video endpoints have power available and documented. If the organization does not provide a UPS ensuring continuous power for DISN Voice Precedence users and FES communications for Voice Video system users, this is a finding. If the organization does not provide transition to long-term alternate power in the event of a primary power source loss, this is a finding.

Fix text

Develop and document in the Voice Video SSP the design criteria for the physical environment of the Voice Video system. The organization must provide a UPS to ensure continuous power for DISN Voice Precedence users and FES communications for Voice Video system users. Additionally, the organization must provide transition to long-term alternate power in the event of a primary power source loss.
