In this episode, Dr Simon McKenzie talks with Dr Samuli Haataja about countermeasures in cyberspace. The right to countermeasures is a mechanism in international law that allows States to take action when they have suffered an international wrong. Some of features of cyberspace challenge this well-established body of rules, and it may need to change to ensure States have an effective remedy to deter foreign cyber attacks.

Samuli researches the public international law aspects of cybersecurity, and his book Cyber Attacks and International Law on the Use of Force: The Turn to Information Ethics was published by Routledge in 2019. He’s also a member of the IEEE Society on Society Implication of Technology.
