Eight hours of backup power must be provided for LAN Infrastructure, WAN boundary, VVoIP infrastructure, and VVoIP endpoints to support Special-C2 users.
An XCCDF Rule
Description
<VulnDiscussion>Unified Capabilities (UC) users require different levels of capability depending on command and control needs. Special-C2 decision makers requiring Flash or Flash Override precedence must have eight hours of continuous backup power at all times. C2 users requiring Immediate or Priority precedence must have two hours of continuous backup power. Interrupting any of the routing or switching infrastructures will disrupt VVoIP service. If the infrastructure is interrupted, command and control communications are disrupted, preventing critical communications from occurring. When implementing a VVoIP system without considering uninterruptible power supply (UPS) needs for the VVoIP controllers and endpoints as well as the entire LAN, and supporting those needs with UPS systems, communications availability is reduced. All elements of the LAN infrastructure, WAN boundary, VVoIP infrastructure, and VVoIP endpoints directly supporting users with precedence needs must be provided with sufficient backup power to meet availability requirements. This reduction in availability threatens facility and personal security and safety as well as life safety during a power failure.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Ensure a UPS system is provided for all parts of the VVoIP infrastructure, including the core LSC/MFSS, adjunct systems providing critical services, SBC, CER, LAN elements, and endpoints. All VVoIP system devices, including voice endpoints and portions of the LAN that directly support one or more Special-C2 users, must be provided at least eight hours of UPS. Document the VVoIP system design with UPS implementation.
NOTE: UPS systems supplying power to infrastructure supporting Special-C2 and C2 users must also support environmental power to prevent equipment failures. This support must be commensurate with the users supported (eight or two hours as appropriate).
