Effectively preventing and combating cyber crime requires a coordinated international approach at different levels. At the domestic level, investigation of cyber crimes requires adequate staff, expertise and procedures. At the international level, investigating cyber crime requires timely action, facilitated by coordination between national law enforcement agencies and the enactment of appropriate legal authority. The paper considers the means for the exchange of technical and forensic expertise between national law enforcement authorities, as well as the need for international deliberations on current and future legal measures for international cooperation in investigating cyber crime. Of particular interest is the possible role of the United Nations or other international organizations. The paper discusses types of crimes envisaged for international electronic networks and explores why such crimes need international attention and combined efforts. Notes
