Tallinn Manual


Cyber Defence Training

The second pillar of the Tallinn Manual Process is designed to operationalise the research results produced under Pillar I. Based on the Tallinn Manual and Tallinn 2.0, the Training Pillar enables students to keep abreast of the most recent and influential research on the legal issues pertaining to both defensive and offensive cyber operations.

Residential Course

First offered in 2012, the International Law of Cyber Operations course has already hosted students from over 35 countries. It examines legal topics that were at the heart of the Tallinn Manual research into applicability of the jus ad bellum and international humanitarian law to cyber operations. It is also folding in research resulting from the Tallinn 2.0 project, which addresses the international legal regime governing cyber operations below the “armed attack” or “armed conflict” threshold.

The Residential Course is delivered twice a year. Its inaugural iterations were offered jointly in Germany by the Centre, NATO School Oberammergau and the United States Naval War College. In 2015, the Residential Course will move to the home of the Centre in Tallinn, Estonia, and be offered by the Centre in cooperation with the United States Naval War College and the University of Exeter. The course is a unique opportunity to attend lectures by noted scholars and practitioners, including co-authors of the Tallinn Manual.

The 5-day Residential Course begins with an optional “tech-day” that introduces the technical aspects of cyber operations; explains how technical attribution is achieved and challenged; describes various actors in cyberspace; and provides an overview of the current status of international cyber affairs.

The 4-day core curriculum consists of two blocks:
1) the peacetime international law governing cyber operations;
2) the international humanitarian law that applies during armed conflict involving cyber operations.
Each 1.5-day session concludes with a complex exercise that allows participants to apply the law addressed during lectures and discussion.
