This course will be taught in person but with the option of remote participation via Zoom.  Please note that this course might become online-only in the event that actual in-person attendance during the semester consistently falls below a threshold to be determined in the exercise of reasonable discretion by the instructor and the Student Affairs Office.

For Spring 2021: If you are enrolled in Prof. Huffman's Privacy Law class and would like to add this to your schedule, please email to request a time conflict override. This is a special one-time exception allowed for these two classes only, space permitting.

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 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.
