Is cyber war a risk that only governments can deal with? Or should enterprises be prepared to mount their own defences?

In this episode we speak to Prof Richard Benham, a UK Government adviser on cyber security, the first professor in cyber security management, Patron of The National Museum of Computing at Bletchley Park, and non-executive director at Emerge Digital.

He believes that, in some ways, a cyber war has already started. He speaks to editor Stephen Pritchard about the reasons why, and sets out what organisations can do to protect their digital assets and infrastructure.
