One of the key issues at this year's LandWarNet conference and symposium is cyber security and operations. Among the challenges to security is the use of military computer networks for purposes they were not originally designed for. Speaking at a panel on the state of Army cyber security and operations, Brig. Gen. Steven W. Smith, chief cyber officer, Army CIO/G-6, noted that "The NIPRNET was never designed at a command and control network, but it sure is now." The service must facilitate cultural change and newly launched initiatives to ensure the security of its networks, he said.
