The Tallinn Manual: Responding to Hostile Cyber operations under International Law

Michael SchmittA lecture by Professor Michael Schmitt, Exeter Law School

8 March 2017
Lecture Theatre 3, The Diamond, University of Sheffield

Professor Schmitt directed the Tallinn Manual “International Group of Experts” that produced the Tallinn Manual in 2013, which dealt with cyber war, and Tallinn Manual 2.0 on peacetime cyber operations in February 2017. His presentation will address the question States most frequently ask of those who participated in the Tallinn Manual process: “How may our State legally respond to harmful cyber operations against our government and private entities that are conducted by other States or non-State actors, such as terrorist groups.” States regularly struggle with this question, as illustrated in incidents ranging from the Sony hack to interference with the recent US elections. Professor Schmitt will outline how the experts approached the subject, and highlight those issues concerning State responses that remain unsettled in the law.
