Same as LAW 279P, The International Law of Cyber Conflict.

This course only meets in person on February 9-10 and March 1-2.

This course is an introduction to how international law applies to hostile cyber activities by States and non-State actors during both peacetime and armed conflict.  Topics addressed range from sovereignty in cyberspace to cyber operations during armed conflict.  It also addresses the responses available to States -- such as retorsion, countermeasures, necessity, and self-defense -- when responding to hostile cyber operations.  The course draws on the Tallinn Manual 2.0 project, which resulted in a restatement of the law drafted over seven years by an international group of experts. The instructor directed that effort, to update to which will be completed in late 2026.

The final exam will be a 24-hour floating exam administered via Canvas, available between March 2 - March 8.
