Government Secure Intranet
From Wikipedia, the free encyclopedia
Government Secure intranet (GSi) is a UK government wide area network, whose main purpose is to enable connected organisations to communicate electronically and securely at low protective marking levels. Many UK government organizations use the GSi, using it to transfer files on a peer to peer basis between similarly accredited networks. Organizations such as GCHQ, The Cabinet Office and SOCA use the GSi for secure purposes. Although many people assume that it is reasonable to assume that MI5 and the SiS also utilise the GSi, in practice they use other networks with enhanced security for high value material.
