The security situation in Europe is determined by new challenges, risks and threats. Security policy is now a cross-cutting issue that needs to be thought along in various areas of politics, like security of IT systems, organized crime, drug trafficking; economic crime, corruption, illegal migration and scarcity of resources. Effective security policy also needs to consider the fact that today's risks and threats are often global in nature. Given the complexity and cross-border nature of the challenges, existing security risks appear to be solvable only through international cooperation. The 7th Network Europe Conference analysed the changing conditions of security in Europe and the common security values, interests and objectives.
