The United States and European Union recently conducted cyber wargame exercises, and have announced plans to cooperate on addressing a wide range of cyber security issues.
The security exercises included select participants from the private sector, and were focused on coordinated responses to cyber-related threat scenarios.
Initiatives lead by the European Network and Information Security Agency (ENISA) include the creation of a cyber response center to react to security events affecting member countries and international partners, which should become active by 2013.
Plans are also in the works to increase the level of information sharing between intelligence agencies, law enforcement and the private sector to enhance detection and response to emerging threats.
Participating nations will also each develop a threat response team modeled after the US Computer Emergency Response Teams (CERTs) by 2012.
Last month UK armed forces Minister Nick Harvey made statements advocating cyber offensive abilities as prudent:
"In every other domain (of warfare) you have the concept of deterrence and... in the fullness of time we would expect to get into a position where people understood our capabilities..."
Also, US President Barack Obama recently met with European Council president Herman Van Rompuy and European Commission president Jose Manuel Barroso in Portugal, then issued a joint statement announcing the formation of a cyber security workgroup.
This follows reports that attacks on critical infrastructure control networks is on the rise, and that nearly one-third of companies surveyed believe they are not equipt to respond to future attacks.
