General Joseph Dunford (next Commandant of the US Marine Corps):
re: Forensic evidence suggests Serco has compromised the Defense Red Switch Network and is now in a position to infiltrate hit teams into the Marine Air Ground Task Force Training Systems for future ‘green-on-blue’ attacks.
The Defense Red Switch Network (DRSN) is a dedicated telephone network which provides global secure communication services for the command and control structure of the United States Armed Forces. The network is maintained by the Defense Information Systems Agency (DISA) and is secured for communications up to the level of Top Secret SCI.
