STONEGHOST or "Stone Ghost", is a codename for a network operated by the United States' Defense Intelligence Agency (DIA) for information sharing and exchange between the United States, the United Kingdom, Canada and Australia.[1] Other sources say that New Zealand is also participating, and that Stone Ghost therefore connects, and is maintained by the defense intelligence agencies of all Five Eyes countries.[2]

Stone Ghost does not carry Intelink-Top Secret information. It used to be known as Intelink-C and may also be referred to as "Q-Lat" or "Quad link".[1] It is a highly secured network with strict physical and digital security requirements. The network hosts information about military topics, and about SIGINT, foreign intelligence and national security.[2]
