Edmund Burton has taken over from Pauline Neville-Jones as chairman of the Information Assurance Advisory Council (IAAC).
A former executive chairman of the Police IT Organisation (PITO), Burton produced a key paper on information assurance in 2001, and supported Cabinet Office moves to introduce a national IA strategy.
IAAC vice-chairman, Neil Fisher, said, "Sir Edmund brings knowledge, commitment and support for the role and objectives of IAAC and for its evolution over the next few years."
A 38-year military veteran, Burton said, "The UK economy depends on the innovative use of IT and communications. Government departments are committed to provide public services through the medium of these technologies. They and their private sector partners will, therefore, be entrusted with the safeguarding of significant quantities of personal, private and sensitive data.
"Ensuring that this important responsibility is understood and effectively undertaken will involve a close partnership between the public and private sectors, the professional institutions and academia. Following the recent issue of the Government IA Strategy, IAAC will be expected to play an increasingly important role, stimulating and sponsoring research and discussion across key communities."
