CSCI E-170 Calendar - Fall 2005

Lecture 1 - Sep 19 : Introduction to Security, Privacy and Usability

The first half of the course covers the fundamentals of computer security, defenses against passive attackers, and defenses against hostile users. The second half of the course explores phishing and active attackers.

Hour 1: Definitions and Goals of Computer Security. Policies and Perimeters. What is a security policy? Who writes it? What does it include? What does it not include? Perimeter definition and Risk assessment. Attack classification. Examination of some sample policies. Discussion of security incidents. Formulation of a security policy for the class website. Military vs. Commercial objectives. Role of Audit and verification. Codes of Ethics.

Hour 2: Understanding Privacy: data disclosure, fair information practices.

Assignment #1 Security Incident released

Please write a one-page (600 word) description of a security incident in which you were personally involved and post it to the CSCI E-170 LiveJournal discussion. Note: in order to complete this assignment, you will need to create a LiveJournal.com account and join the community.

Remember: information posted to LiveJournal is not secure. For this reason, your report should be appropriately sanitized so that it does not contain any information that cannot be publicly released. Specifically, be careful not the compromise the privacy of any individuals involved (unless the details have already been made public).

Lecture 2 - Sep 26 : Physical Security and Information Leakage

Hour 1: Locks and master keys. Tempest. Soft tempest. Optical Tempest.

Hour 2: Information left on hard drives.

Assignment #1 due

Assignment #2 Disk Forensics released

Obtain a storage device with more than 32MB of memory from yourself or a friend. Image the device's memory and write a 3 page report about what you find. Your report should be sanitized --- that is, the report should not include any personal information that would allow the identification of any data subjects. Be sure to discuss the tools you used, the files, deleted files, and data in the slack space. If the USB device that you have is not sufficiently interesting, or if you are unable to find one that you can image, you may use one of the images from the class website.

Although you have 2 weeks to work on this Assignment, do not wait until the second week before you start. This can be a very interesting assignment. Be sure to give it the time that it is worth. It is highly recommended that you post a status report to the class LiveJournal discussion.

You can find more information in the HW2 FAQ on the home page.

If you are unable to create your own disk image, you can download a 32MB disk image provided for the class.
