Cyber security has become a matter of global interest and importance. Already more than 50 nations have officially published some form of strategy document outlining their official stance on cyberspace, cyber crime, and/or cyber security (Klimburg, 2012). The Whitehouse (2011) has outlined a cyber strategy that provides the stance of the United States of America (USA) on cyber-related issues and outlines a unified approach to the USA's engagement with other countries on cyber issues. The United Kingdom (UK) lists cyber security as a top priority and has committed £650 million over four years for a transformative National Cyber Security Programme (Minister for the Cabinet Office and Paymaster General, 2011). However, very few of these sources seem to make a distinction between the concepts of cyber security and information security or the relationship between them.
In most literature, cyber security is used as an all-inclusive term. Definitions of this term vary, for example the Merriam Webster dictionary defines it as “measures taken to protect a computer or computer system (as on the Internet) against unauthorized access or attack”
