The Tallinn Manual, or Manual on the International Law Applicable to Cyber Warfare (MILCW), is nearing completion. While the book version is getting its finishing touches at Cambridge University Press (scheduled to publish in early 2013), the soft copy is now available on the NATO CCD COE website. [NB! Be sure to note the disclaimers about the status of the manual!]
I had the pleasure to participate in the development of this very interesting Manual for three years. As one of the 'Technical Experts', my role was to explain various cyber and computing concepts to the lawyers, as well as participate in creating many of the examples found in the book.
I wish to thank the group, for it was fascinating work and I learned a great deal in the process.
