This course navigates international law and the law of war as it applies to the notion of cyberwar. Using and applying select rules of the Tallinn Manual, which is an expert analysis of law applicable to cyberwar, you will be able to understand and analyze the challenges of using law to address cyberattacks, cyberthreats and cyberwar. With this knowledge, the course will progress to applying the law to two case studies: the Sony Entertainment cyberattack and a less well known attack where a group of hackers in Iran attacked a dam in the United States. Finally, a look toward the future possibility of a cyberwar and the rule of law concludes this course.
