The Enterprise Voice, Video, and Messaging Session Manager supporting Command and Control (C2) communications must associate multilevel precedence and preemption (MLPP) attributes when exchanged between unified capabilities (UC) systems.

Description
If MLPP attributes are not associated with the information being transmitted between systems, then access control policies and information flows which depend on these MLPP attributes will not function and unauthorized access may result. Without the implementation of safeguards which allocate network communication resources based on priority, network availability, and particularly high priority traffic, may be dropped or delayed. DOD relies on the implementation of MLPP to ensure that flag officers and senior staff are provided higher priority for communications than other users. For VoIP and videoconferencing systems, Enterprise Voice, Video, and Messaging Session Managers must communicate using protocols and services that provide expedited packets to users and other systems.

ℹ️ Check
Verify the Enterprise Voice, Video, and Messaging Session Manager supporting C2 communications associates MLPP attributes when exchanged between UC systems. If the Enterprise Voice, Video, and Messaging Session Manager supporting C2 communications does not associate MLPP attributes when exchanged between UC systems, this is a finding.

✔️ Fix
Configure the Enterprise Voice, Video, and Messaging Session Manager supporting C2 communications to associate MLPP attributes when exchanged between UC systems.
