The Defense Intelligence Agency runs the federal government's top-secret IT network. DIA is in the middle of a major modernization of that network.

Cybersecurity is also essential, both to defend against outside hackers and prevent insider threats. For the latest, I spoke with DIA Chief Information Officer Doug Cossa.
