Piracy, of which we hear more and more frequently, affects specific geographic areas – mainly the Indian Ocean and part of the Atlantic Ocean. Over the last three years, there were 16 attacks against Italian ships or foreign ships managed by Italian societies. The rules nowadays in force were adopted by IMO (International Maritime Organization) in 2002 with the new ISPS Code (International Ship & Port Facility Security Code), followed by the Regulations n. 725/2004 promulgated by the European Parliament. The concept of security introduced by this law emphasizes the fact that, in order to guarantee excellent standards of security, ships and ports must be well organized, protected and connected. Anyway, the huge crime rise of the last three years has forced the sector of maritime transport to adopt new measures of prevention and protection to answer to this menace in a fast and effective way. In Italy, the Law n. 130/2011 authorizes ships crossing dangerous seas to embark teams of soldiers or armed members of private security companies.
