The Secret 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".{{Cite book|url=https://www.worldcat.org/oclc/946756401|title=Us defense information systems agency handbook.|date=2007|publisher=Intl Business Pubns Usa|isbn=978-1-4330-5548-5|location=[Place of publication not identified]|oclc=946756401}} 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.{{cite web|url=https://fas.org/irp/program/disseminate/siprnet.htm|archive-url=https://web.archive.org/web/19970726161029/http://www.fas.org/irp/program/disseminate/siprnet.htm|url-status=dead|archive-date=July 26, 1997|title=Secret Internet Protocol Router Network (SIPRNET)|publisher=Federation of American Scientists' Intelligence Resource Program|access-date=12 December 2010}} 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.
