  • Most of your requests (clarifications, questions about upcoming deadlines, projects, etc.) should be publicly asked on Piazza, so that other students can benefit from Q&As.
  • If you need to ask me something personal (that does not apply to the entire class), then you can send me an email. If you need to reach me through email, make sure your title starts with "[CSE 361]" (without the quotes). Mislabeled or unlabeled emails will, most likely, not be read.


Class Description

In this class, we will together explore the concepts behind web security. We will look at the core principles behind secure (and insecure) systems and how these principles apply to web applications. We will learn how the web works, how to find vulnerabilities, how attackers compromise web applications, and how to avoid these vulnerabilities when implementing and deploying your own web applications.

The course will consist of lectures, hands-on labs (likely done on the laptops of the students in class), a few select paper presentations by teams of students, and one (or two) small projects.

Some of the topics that we will cover are the following:
