DISN
The Defense Information System Network (DISN) has been the United States Department of Defense's enterprise telecommunications network for providing data, video, and voice services for 40 years. The DISN end-to-end infrastructure is composed of three major segments: *The sustaining base (I.e., base, post, camp, or station, and Service enterprise networks). The Command, Control, Communications, Computers and Intelligence (C4I) infrastructure will interface with the long-haul network to support the deployed warfighter. The sustaining base segment is primarily the responsibility of the individual Services. *The long-haul transport infrastructure, which includes the communication systems and services between the fixed environments and the deployed Joint Task Force (JTF) and/or Coalition Task Force (CTF) warfighter. The long-haul telecommunications infrastructure segment is primarily the responsibility of DISA. *The deployed warfighter, mobile users, and associated Combatant Comman ...

Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications pro ...

Global Information Grid
The Global Information Grid (GIG) is a network of information transmission and processing maintained by the United States Department of Defense. More descriptively, it is a worldwide network of information transmission, of associated processes, and of personnel serving to collect, process, safeguard, transmit, and manage this information. It is an all-encompassing communications project of the United States Department of Defense. The GIG makes this immediately available to military personnel, to those responsible for military politics, and for support personnel. It includes all infrastructure, bought or loaned, of communications, electronics, informatics (including software and databases), and security. It is the most visible manifestation of network-centric warfare. It is the combination of technology and human activity that enables warfighters to access information on demand. It is defined as a "globally interconnected, end-to-end set of information capabilities for collecting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIPRNet
The Secure Internet Protocol Router Network (SIPRNet) is "a system of interconnected computer networks used by the U.S. Department of Defense and the U.S. Department of State to transmit classified information (up to and including information classified SECRET) by packet switching over the 'completely secure' environment". It also provides services such as hypertext document access and electronic mail. As such, SIPRNet is the DoD's classified version of the civilian Internet. SIPRNet is the SECRET component of the Defense Information Systems Network. Other components handle communications with other security needs, such as the NIPRNet, which is used for nonsecure communications, and the Joint Worldwide Intelligence Communications System (JWICS), which is used for Top Secret communications. Access According to the U.S. Department of State Web Development Handbook, domain structure and naming conventions are the same as for the open internet, except for the addition of a second ...

NIPRNet
The Non-classified Internet Protocol (IP) Router Network (NIPRNet) is an IP network used to exchange unclassified information, including information subject to controls on distribution, among the private network's users. The NIPRNet also provides its users access to the Internet. It is one of the United States Department of Defense's three main networks. The others include SIPRNet and JWICS. History 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. Security improvements In the year leading up to 2010 NIPRNet has grown faster than the U.S. Department of Defense can monitor. 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. The NIPRNet survey, which use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
