NIPRNet

[3] NIPRNet is composed of Internet Protocol routers owned by the United States Department of Defense (DOD).

It was created in the 1980s and managed by the Defense Information Systems Agency (DISA) to supersede the earlier MILNET.

DoD spent $10 million in 2010 to map out the current state of the NIPRNet, in an effort to analyze its expansion, and identify unauthorized users, who are suspected to have quietly joined the network.

[4] The NIPRNet survey, which uses IPSonar software developed by Lumeta Corporation, also looked for weakness in security caused by network configuration.

[5] The Department of Defense has made a major effort in the year leading up to 2010, to improve network security.
