An OSC specializing in developing directed energy systems plans to bid on a DoD contract to produce a 250kW High Energy Laser Weapon System (HELWS). This system is to be deployed on military bases across the globe to protect U.S. servicemen against aerial threats, including mortars, rockets, and unmanned aerial vehicles (UAVs), as well as swarms of mini-UAVs. Because of the sensitivity of the information, the OSC has prohibited using emails to transmit information regarding the project, whether encrypted or otherwise. They also have instituted procedures to remove CUI from the email system. What CMMC assessment requirements must the Assessment Team follow regarding the OSC’s email system?
