Lt. General Harry Raduege, chairman of Deloitte & Touche's Center for Network Innovation, said some of the group met in June to construct a blueprint for their work, and the full panel will reconvene Friday. Some issues they will tackle include authentication of Internet users, international engagement, and how to scale security solutions while preserving privacy and civil liberties, Charney and Raduege said. Charney said the commission was pleased with its 96-page original report but drafting that analysis brought up a host of new questions about the 21st century cyber infrastructure. "The appropriate response to problems will not be the traditional response of many years ago," he said.
