The Open Source Information System was an unclassified network of computer systems that provides the intelligence community with open source intelligence. As of 2006, the OSIS name was retired and the network and content portions of the system were decoupled. The network portion of the system is now called DNI-U and the content portion is known as Intelink-U. According to the Army Foreign Military Studies Office, “Intelink-U is a virtual private network — a government intranet. It provides a protected environment to exchange unclassified and FOUO/SBU US Government and other open source data among Intelligence Community and other selected organizations. The Intelink-U firewalls safeguard government information resources and allow customers access to both the Intelink-U network and the public Internet. This gives Intelink-U users a single point of access to an unprecedented amount of unclassified open source information. “
