The use of cyber force can be as severe and disruptive as traditional armed attacks are. Cyber attacks may neither provoke physical injuries nor cause property damages and still, they can affect essential functions of today’s societies, such as governmental services, business processes or communication systems that progressively depend on information as a vital resource. Whereas several scholars claim that an international treaty, much as new forms of international cooperation, are necessary, a further challenge should be stressed: authors of cyber (...) attacks can be non-state actors, and identifying the party responsible for such a use of force, whether non-state actors or national sovereign states, is often impossible. Accordingly, several programmes on online security and national defence have been developed by sovereign states to tackle this menace and yet, the endurance of Western democracies and their aim to protect basic rights have already been tested by such programmes over the past years. The new scenarios of cyber force do not only concern the field of international law, since they may represent the main threat in the fields of national and constitutional law as well. (shrink)

The paper examines today’s debate on the new responsibilities of Internet service providers in connection with legal problems concerning jurisdiction, data processing, people’s privacy and education. The focus is foremost on the default rules and safe harbour clauses for ISPs liability, set up by the US and European legal systems. This framework is deepened in light of the different functions of the services provided on the Internet so as to highlight multiple levels of control over information and, correspondingly, different types (...) of liability. The new responsibilities of ISPs concern the original “end-to-end” architecture of the medium and policies on design rather than responsibility for user content and individual messages. (shrink)
