Manual on International Law Applicable to Cyber Warfare

Following the initiative of the Centre and its partners from academia, a group of world-class international law and law of armed conflict experts regularly meet to bring clarity to the applicability of the law of armed conflict to cyber incidents. The group’s work is intended to lead to a restatement and manual on the international law applicable to cyber warfare, similar to the manuals on the law applicable to armed conflicts at sea (1994) and air and missile warfare (2010).

The Tallinn Manual is forthcoming in both paper and electronic copies from Cambridge University Press (© Cambridge University Press 2013). However, you can already preorder the Tallinn Manual hereThe draft version of the Manual can be accessed from our webpage.
