Overview

This course is an introduction to the broad field of network security (e.g., maintaining confidentiality of email, secure web transactions). We will stay close to the text, covering as much of it as we can, certainly including chapters 1-7 and 9-18.

Course topics (regularly updated)

Texts/Notes

(Required text) Network Security: Private Communication in a Public World, 2nd edition by Kaufman, Perlman, and Speciner. ISBN 0-13-046019-2.

Grading

Midterm --- 30% (Nov 1)
Final ------- 30% (Thu Dec 13 8:00-10:00 am)
Homeworks (including programming projects) --- 30%
- Project 1: posted Sep 26, due Oct 2.
- Project 2: posted Nov 11, due Dec 8.

Remaining 10% to be allocated later.

Practice exams

The only "practice" exams I will post will be the midterm exams from previous semesters, which are also publicly available on the previous class web pages. I suggest you don't look at this exam prematurely. In my opinion, the best use of this exam is to first prepare for this semester's midterm and then do the practice exam under exam conditions (including time duration) and see how you score (the scoring guidelines are also included in the exam solution).

Homeworks

Most (but not all) of the homework problems are repeated from previous semesters, and their solutions are publicly available on the previous class web pages. Such homework problems will have a small weight in the final grade. So
- Don't worry if you get a low score on such homework problems.
- It's rather pointless to hand in a copy of the posted solution.
- Understanding the solution can help you in the exams.
Late homeworks will not be accepted; turn in whatever you have completed by the deadline.
Homeworks will be done individually. You may consult outside references when doing the homework, as long as these sources are properly referenced, you write up the solution yourself, and you understand the answer. For example, if you look at other source code, you may not copy the code directly in your program, but you may model your program after it. And you must reference it!
