Campbell: Keep SIPRnet separate from NIPRnet

When not speaking about his favorite pet peeve'lack of bandwidth'Lt. Gen. William H. Campbell likes to talk about security.

The Army chief information officer rejected the notion that the Defense Department's classified and unclassified networks could run interchangeably on users' systems.

'We can't allow high-assurance guards to separate' the Non-Classified IP Router Network and the Secret IP Router Network, said Campbell, the Army's director of information systems for command, control, communications and computers.

Say what?

Speaking at the recent Armed Forces Communications and Electronics Association's TechNet conference, he called the term 'high-assurance guard' an oxymoron.

High-assurance guards on networks scan message packets for expressions and keywords.

In the case of SIPRnet and NIPRnet, a high-assurance guard would look for parentheses and special markers for the beginning of paragraphs that characterize classified messages, Campbell said.

Campbell said he favors using virtual private networks and continued physical separation to keep NIPRnet and SIPRnet transmissions secure.

Campbell made his comments just weeks before he was to retire. Maj. Gen. Peter M. Cuviello, commanding general for the Army Signal Center at Fort Gordon, Ga., this month will take over for Campbell as the Army's CIO.
