This syllabus is a guideline for the course and not a contract. As such, its terms may be altered when doing so is, in the opinion of the instructor, in the best interests of the class.

Required Text

Charles P. Pfleeger and Shari Lawrence Pfleeger, Security in Computing, 4th edition, Prentice-Hall, 2007, ISBN 0-13-239077-9

The course textbook is also available in an online edition; a limited number of people from UW can be using the online edition at one time. If you are off-campus, you can use the library's proxy service.

Other Resources


This course provides an introduction to security and privacy issues in various aspects of computing, including programs, operating systems, networks, databases, and Internet applications. It examines causes of security and privacy breaches, and gives methods to help prevent them.

Students completing this course should be better able to produce programs that can defend against active attacks, and not just against random bugs.

Intended audience

Third or fourth year CS students (CS 458), or first year CS graduate students (CS 658)


CS 350 (Operating Systems). Familiarity with C.


Introduction to Computer Security and Privacy (1.5 hours)
The meaning of computer security; comparing security with privacy; types of threats and attacks; methods of defense
Program Security (6 hours)
Secure programs; nonmalicious program errors; malicious code; controls against program threats
Operating System Security (6 hours)
Methods of protection; access control; user authentication
Network Security (4.5 hours)
Network threats; firewalls, intrusion detection systems
Internet Application Security and Privacy (9 hours)
Basics of cryptography; security and privacy for Internet applications (email, instant messaging, web browsing); privacy-enhancing technologies
Database Security and Privacy (4.5 hours)
Security and privacy requirements; reliability, integrity, and privacy; inference; data mining; k-anonymity
Non-technical Aspects (4.5 hours)
Administration of security systems; policies; physical security; economics of security; legal and ethical issues

It is expected that you will have read the appropriate sections of the textbook (as noted in the Calendar section of LEARN) before class. Additional readings may be assigned as well, and will appear on the lecture slides page; those readings marked as mandatory contain required material for the course; those marked before class must be read before the date of the corresponding lecture.

Grading Policy

Grades will be calculated as follows:

If the weighted average of your exam marks is below 50%, you cannot pass the course.

Midterm exam time/location: Tue, Feb 14, 2012, 7:00 pm, MC 4020, 4021
Final exam time/location: Wed, Apr 11, 2012, 12:30 pm, PAC 11, 12

The midterm and final are closed-book exams. The midterm covers all material presented up to that point in the course. The final exam covers material from the whole term, with emphasis on the second half of the course. Midterms will be returned in class.

Assignments are to be submitted electronically with the "submit" command, and are due at 3:00 pm Eastern Time on their respective due dates. Assignments submitted by other means will not be accepted. Students should make sure early on that the "submit" command works for them. Students should check whether their submitted files correspond to the ones that they intend to submit using the "-print" option of the "submit" command.

Late submissions for assignments (not including the blog task and the self-tests) will be accepted only up to 48 hours after the original due date. There is no penalty for accepted late submissions, and multiple assignments can be submitted late, including the last one. Course personnel will not give assistance for assignments after their original due dates. Due dates will be posted well in advance in the Calendar section of the LEARN course site. Assignments will be returned in class (if on paper) or by email to students' email addresses (if electronic).

Self-tests are meant to help you keep up with the material, and gauge your grasp of it (at a basic level) on an ongoing basis. The availability and deadline information will be posted on LEARN. You can attempt each self-test as often as you like during its availability period; your last grade on each self-test will be the one recorded (although course personnel can see every attempt). No late self-tests will be accepted for any reason, including being late to join the class.

It is your responsibility to keep up with all course-related information posted to LEARN.

Reappraisal Policy

Each assignment and the midterm has a Lead TA assigned (see below). If you have an assignment or exam that you would like to have reappraised, please provide the Lead TA with a written request (on paper or by email), including a justification for your claims, and any related material (such as your original assignment). If your appeal is concerned with a simple calculation error, please see the instructor or Lead TA during his or her respective office hours. The appeals deadline is one week after the respective graded item is first made available.


Please direct all communication to the discussion forum on Piazza. If there is a good reason not to use the discussion forum (e.g., personal matters, a question that might reveal part of a solution, etc.) contact course personnel directly via LEARN email. Please use regular email only as a last resort, and then it must be from your email address. Course personnel may decide that an email message is more appropriate for Piazza and repost it there. For assignments, emails with questions about the assignment that cannot be sent to the discussion forum should be sent to the Lead TA.

Important course information will generally be posted to Piazza or LEARN, but may also be sent to you via LEARN email or your email address. It is your responsibility to monitor all of these channels.

Research Paper (CS 658)

Students registered in CS 658 must write a research survey paper on a topic related to computer security or privacy. Your topic must be approved in advance by the instructor. In writing your paper, you must become familiar with the research literature relevant to your topic. Your paper should be a summary of past and current work on your topic, as well as an overview of known open problems and potential future directions in the area. You should provide a concise summary of work, emphasizing major accomplishments, rather than a detailed accounting of individual pieces of research activity; your paper should not be very lengthy. The research paper will account for 20% of your overall mark with the other 80% following the proportions of the CS 458 formula. You must submit a one-page proposal to the instructor by February 3. It is recommended but not required that you discuss the proposal with the instructor first. Additional milestones for the completion of the paper will be set. The final version is due on April 2.

Teaching Assistants

Academic Integrity

Students are encouraged to talk to one another, to the TAs, to the instructor, or to anyone else about any of the assignments. Any assistance, though, must be limited to discussion of the problem and sketching general approaches to a solution. Each student must write his or her own solutions, including code and documentation if appropriate, for the assignments. Consulting another student's solution is prohibited, and submitted solutions may not be copied from any source. These and any other forms of collaboration on assignments constitute cheating. If you have any questions about whether some activity constitutes cheating, please ask the instructor.

The general Faculty and University policy:

Note for students with disabilities

The Office for Persons with Disabilities (OPD), located in Needles Hall, Room 1132, collaborates with all academic departments to arrange appropriate accommodations for students with disabilities without compromising the academic integrity of the curriculum. If you require academic accommodations to lessen the impact of your disability, please register with the OPD at the beginning of each academic term.

Security Information

In this course, you will be exposed to information about security problems and vulnerabilities with computing systems and networks. To be clear, you are not to use this or any other similar information to test the security of, break into, compromise, or otherwise attack, any system or network without the express consent of the owner. In particular, you will comply with all applicable laws and UW policies, including, but not limited to, the following:

Violations will be treated severely, and with zero tolerance.
