The DISN Capstone Requirements Document states that the decision process to select and implement security safeguards must balance the reduction of risk against the cost of protection, taking advantage of commercial products and services wherever possible. DISN's private ATM strategy is costly because it duplicates investments already made in public networks, lacks economies of scale, requires significant surge capacity and does not allow for rapid technology upgrades, the Sprint report said. The Office of the Assistant Secretary of Defense for Command, Control, Communications and Intelligence also received a copy of the Sprint report and is studying it, DOD spokeswoman Susan Hansen said. Strong support DISA continues to support the use of ATM technology for DISN, the high-speed backbone that will provide DOD users with global connectivity through wideband transmission services managed by commercial carriers. DISN equipment is owned and operated by the carriers.
DISA provides direction and monitors the network.
But the Sprint report concluded that the same level of control now enjoyed by DISA can be achieved using public ATM networks. All rights reserved.
