A few days ago I wrote an article on cyber espionage and its higher incidence in the computer crimes. An interest in cyber espionage has been demonstrated by government agencies in search of sensitive information and information relating to industrial technologies used by hostile countries. Of strategic importance for espionage activities are the social networks, a valuable mine of information through which you can trace the profile of an individual, knowing relations, customs and even the spatial and temporal location. For this reason, I believe that the usage of social networks by the key person inside military agencies and industrial environments must be subjected to a stringent regulation.”]
