CS294-28: Network Security. Prerequisite: EE122 or equivalent, knowledge of basic network security notions, basic probability/statistics.
This class aims to provide a thorough grounding in network security suitable for those interested in conducting research in the area, as well as students more broadly interested in security or networking. Topics will include: denial-of-service; capabilities; network intrusion detection; worms; forensics; scanning; traffic analysis; legal issues; web attacks; VOIP security issues; anonymity; wireless security; botnets and honeypots; and research pitfalls.
The course is taught with an emphasis on seminal papers rather than bleeding-edge for a given topic. It includes a major project each student undertakes individually or in pairs. The class is intended to evolve into a regular graduate offering, and the syllabus has substantial overlap with portions of the SEC prelim.
Three hours of lecture per week. (3 units)
See the syllabus.
There will be a term project. You will do independent research in pairs or individually. Projects may cover any topic of interest in network security, interpreted broadly (it need not be a topic discussed in class); ties with current research are encouraged. See the project description for details and due dates for the different elements.
You are encouraged to start thinking of topics of interest early. Be ambitious!
There is no required textbook. All reading will be from papers. A tentative list of these is available from the syllabus. We will definitely cover most of these topics (and primary papers), but as this is course is under development I may make some changes.
Homework for the course primarily consists of writing a "mini-review" of each paper you read. In general you are only responsible for reading the first paper listed for a given topic. If you want to read and review a different paper instead, in general that's okay, but clear your choice with me in advance.
Submit your mini-review, via email, by Tuesday 9AM for papers discussed during a Wednesday lecture, and Friday 1PM for papers discussed during a following-Monday lecture. Your mini-review should give briefly sketch each of the following:
Your mini-review does not need to be particularly formal, but it needs to reflect a thoughtful assessment of the paper. (It is understandable that you may find parts of some papers baffling or inaccessible. Flag these and don't kill yourself trying to absorb them - same goes for technical fine points - but use prudence in this regard.) If there are particular elements of your mini-review for which you'd like direct feedback, indicate them in your writeup.
Note, mini-reviews are to be done individually. It's fine to discuss the readings with your fellow students or others in order to gain comprehension, but the writeup should reflect your own views and framing.
Late mini-reviews lose 50% credit off the top. Writeups turned in after the scribe notes (see below) receive no credit.
You will be expected to write scribe notes for a couple of lectures (the number depends on the class size). Email me document source (latex, HTML, Word) with your scribe notes suitable for editing and posting on the course Web site. For full credit, I need to receive it within one week after the corresponding lecture.
Inspect the syllabus and send me a note regarding which lecture(s) you'd prefer to scribe. I will allocate scribes in first-come-first-serve order.
We will be discussion attacks, some of them quite nasty, and also powerful eavesdropping technology. None of this is in any way an invitation to undertake these in any fashion other than with informed consent of all involved parties. If in any context you are uncertain about where to draw the line, come talk with me first.
The course uses a mailing list for announcements and discussions, so it is important for students to subscribe to it.
The schedule here will be updated as the course progresses. The intent is to aim for a lecture per topic in the syllabus, but will be updated here closer to the actual date to correctly reflect the actual lecture.

Student feedback in general is always highly valuable. As this class is under development and intended to evolve into a regular grad offering, it is particularly valuable for this course!
