Overview

This course is an introduction to the broad field of information security. We will cover both network security (e.g., maintaining confidentiality of email, secure web transactions) and computer security (e.g., security policies, access control), with emphasis on the former. Note that there is not always a clear dividing line between the two areas.

Texts/Notes

(Required text: used a lot) Network Security: Private Communication in a Public World, 2nd edition by Kaufman, Perlman, and Speciner. ISBN 0-13-046019-2.
(Other texts: not used a lot) Security in Computing, 3rd edition by Pfleeger and Pfleeger.

Grading

Midterm --- 30% (Tue April 18)
Final ------- 30% (Thu May 18 1:30-3:30 pm)
Homeworks --- 40%

The weightages are approximate and may change by upto 10%.

Homeworks:

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!
