Communities, countries and alliances cannot be efficient in preparing to meet diverse threats to their security
within traditional organizational stovepipes. The boundaries between ‘internal’ and ‘external’ threats are getting fuzzier, and the vulnerabilities of governments, businesses and communities feed on each other, while the
