Over the past years, the debate over cyber-security has become one of the hottest debates in Internet and security policy. The term "cyber-security" captures a number of different problems: economic espionage by state actors, competitors or criminals; criminal activity such as fraud and the theft and exploitation of personal information; and attacks by state actors or terrorists on critical infrastructure. While these problems will often call for different solutions, they share a common root cause: as the Internet has permeated every area of our lives, we have become increasingly vulnerable to attacks on the computers and networks that make up the Internet. A growing stream of high-profile cyber attacks against firms, government organizations and networks (civilian and military), international organizations, and universities highlights this vulnerability. While policy makers and businesses have recognized the significance of the threat and have started to take action, potential solutions are hotly contested and far from clear. The seminar aims to enable students to participate in the ongoing policy debates over cyber-security and to take steps to improve cyber-security in their private and professional lives. We will discuss the economic, technical and psychological factors which make improving cyber-security such a hard problem and will explore how law and technology can be used to address it. We will explore whether private incentives can be leveraged to improve the level of security, what role the government should take, and whether there are solutions that improve security while protecting civil liberties and the factors that are at the core of the Internet's economic, social, cultural and political potential. Students will write a number of short reaction papers in response to the assigned readings and will be expected to participate in the class discussion. Class attendance is required. Instead of reaction papers, students can opt to write a final research paper with consent of the instructor, which meets the Research requirement. The class is open to law students and students from other parts of the university. It does not require any technical background. Special Instructions: After the term begins, students accepted into the course can transfer from section (01) into section (02), which meets the R requirement, with consent of the instructor. Writing (W) credit is for 3Ls only. Elements used in grading: Class participation, attendance, several short reaction papers or final research paper. Consent Application: To apply for this course, students must complete and e-mail the Consent Application Form available on the SLS Registrar's Office website (see Registration and Selection of Classes for Stanford Law Students) to the instructors. See Consent Application Form for submission deadline.
