This page is organized by the weeks of the quarter in which lectures were given. The weeks are in inverse order, on the assumption you will most often be looking for the most recent week.
This class will be taught by Peter Reiher. The textbook is Computer Security: Art and Science, by Matt Bishop. Assigned readings are from this book, unless otherwise indicated. Dr. Bishop has also published a second textbook that contains selected sections of this book, with a similar title. I can't guarantee that all material assigned will actually be in this other book, and it will definitely be at different pages if it's there at all.
The TA for the course is Yiannis Pefkianakis -- pefkian@cs.ucla.edu. The labs for this course will consist of 5 hands-on, practical and exploratory projects covering security-related topics, plus a small introduction to the lab software. Office hour and discussion section information, the lab manual and all necessary materials for the labs are located here.
No readings from the textbook this week.

Slides:
Note that I have made small modifications to some of these lectures that are not reflected in the taped versions. Other than clarifying wording, these tend to be updates to things that change from year to year, such as DNSSEC deployment status. Because the changes are not substantial, I have not retaped the lectures. So be sure to compare the slides posted here to what appears in the taped lectures.
No textbook assignment for this week.

Note: I have updated some of the slides in the Powerpoint presentations for lecture 12, but I have not retaped the lecture from last year. The changes are minor and mostly represent updated statistics and examples. You should both view the videos and look over the slides in the presentations, however, to make sure you get the most up-to-date information. If anything about the differences in the slides from the videos is not clear, please ask me about it.

Because of the midterm, which will be on Saturday, May 2, 1-3 PM, only one lecture is assigned this week.
The midterm examination is open book, open notes. It will consist of three essay questions on issues covered in lectures and readings. Everything discussed in the first nine lectures and all assigned readings (except those explicitly identified as not being tested) are possible materials for the test. Here is a sample midterm that is similar in style to the one you will be given.
The midterm will be held in 2258A Franz Hall, on the UCLA campus, unless you have made arrangements for taking it at a remote proctored location.

A short, informal performance comparison of some full-disk encryption products available a couple of years ago. While somewhat outdated, this can give you some idea of the price/performance of the technology. I'm not going to test you on it, but this Seagate web page is worth looking at to get an idea of the commercially available hardware for full disk encryption.

A discussion on choosing secure passwords.
A short essay on the limits of using biometrics by Bruce Schneier. This essay is embedded in a longer newsletter. You need only read the section titled "Biometrics in Airports".
Tsutomu Matsumoto, Hiroyuki Matsumoto, Koji Yamada, Satoshi Hoshino, "Impact of Artificial "Gummy" Fingers on Fingerprint Systems.", Proceedings of SPIE Vol. 4677, January 2002. A reality check on the promise of a particular biometric. While this is not a new paper any more, and it's possible that recently developed fingerprint readers do better, it's a useful general caution about getting too enamoured of the promise of any particular biometric technology.
I. Dubrawsky, Cryptographic Filesystems, Part One: Design and Implementation,. A short web article describing basic approaches to cryptographic file systems and outlining the designs of a few well known examples.
J. Alex Halderman, Seth D. Schoen, Nadia Heninger, William Clarkson, William Paul, Joseph A. Calandrino, Ariel J. Feldman, Jacob Appelbaum, Edward W. Felten, Lest We Remember: Cold Boot Attacks on Encryption Keys, Usenix Security Symposium, 2008. One of those papers that suddenly undermines a security assumption we'd all relied on. In this case, the assumption that RAM loses its data when power is turned off. It's particularly relevant to things like software full disk encryption, one of the technologies discussed in lecture 8.

Bruce Schneier's informal analysis of the meaning of the attack on SHA-1. You only need to read the article itself, not the lengthy sets of comments and responses that follow it. If you'd like to develop a deeper understanding of the issues involved in secure hashes related to collisions, the topic is discussed at length in these comments, but you aren't required to read them.
