Why Is the Army Phasing Out DMUC?
The Army said Monday that support for all DMUC devices will cease on May 30. The Defense Information Systems Agency already issued an advisory that introduced a new mobile device management approach incompatible with the Army 365 environment, forcing the service to end the DMUC program.
To maintain secure connectivity, the Army is urging commands to disenroll government-furnished mobile devices from the DMUC program and turn them in before the end of the month.
“The DMUC program transition is a necessary modernization step in our ongoing transformation efforts,” Lt. Gen. Jeth Rey, Army deputy chief of staff, G-6, stated.
DMUC, which began its rollout in 2014, was designed to provide a secure mobile environment for DOW personnel to meet changing security requirements and incorporate new advancements in technology.
The program supported iPhones, iPads, Samsung tablets, BlackBerry phones and Motorola devices.
What Is the Army Mobility Program?
According to Rey, AMP will provide personnel with flexible, secure and user-friendly mobile access. The program is also intended to reduce the need for personnel to carry separate government-issued devices, he added.
The preferred connectivity option under the program is a bring-your-own-device, or BYOD, approach that allows personnel to use personal devices for official work through secure applications such as Hypori and Mobile Application Management. The applications create encrypted and isolated environments for government activities.
Personnel who need a dedicated government-furnished equipment may still retain or receive devices if approved by senior leadership.
AMP currently supports Apple’s iOS. All personnel who use Android phones or other platforms are requested to coordinate with their S6/TCO.
