Sir Iain Lobban, Director GCHQ, contributed an article entitled "Countering the cyber threat to business" for the Spring 2013 edition of the Institute of Directors Big Picture policy journal.

In the article, Director describes the nature and scale of the threat to businesses from cyberspace, why cyber security should be at the top of boards' agendas and the role GCHQ is playing in helping counter the threats.

The article acts as a foreword to some practical steps on how business leaders and boards can make their organisations safer from cyber attacks.
