The Internet continues to grow in importance for service deliveries for businesses, government, and private entities (i.e. via social networks). Governments and businesses of all sizes have reported that internet connectivity is crucial in their day-to-day operation. They have also reported that they have been affected in some way by cyber attacks. Security measures and policies are developed to counter known threats and risks. However there may be unintended weaknesses in a security measure, or new previously unknown types of attacks to which a security measure is vulnerable, or new Internet services and Internet protocols for which security implications are not yet fully understood. A set of security measures may hence be insufficient to provide a reliable assurance against attacks.
