Welcome to CS 526 (Information Security)!

Instructor: Christina Garman (clg@purdue.edu)

TA: Farzad Zafarani (farzad@purdue.edu)


Course catalog: Basic notions of confidentiality, integrity, availability; authentication models; protection models; security kernels; secure programming; audit; intrusion detection and response; operational security issues; physical security issues; personnel security; policy formation and enforcement; access controls; information flow; legal and social issues; identification and authentication in local and distributed systems; classification and trust modeling; and risk assessment.

You should hopefully come out of this course with a broad understanding of information security, focusing on software security, network security, cryptography, mobile platform security, and privacy technologies, as well as how these security issues can impact real world systems.

Time: M/W/F 12:30pm-1:20pm
Location: Lawson 1106



Farzad's office hours will be TBD.
My office hours will be TBD in my office (Lawson 1185).

I will be available by appointment as well.


Expect that there to be approximately four large projects with a few small assignments mixed in and two exams (a midterm and a final), with the approximate weights as follow. Part of your grade will include a participation component, so I do expect you to attend class, participate on Piazza, etc. If you cannot make class for any reason (such as job interviews, etc.), please let me know as you will not be penalized for this.

Assignments are due at the beginning of class at 12:30pm on the stated due date. Late assignments will be penalized 5 percentage points per day. There is no collaboration allowed on exams. You must do only your own work. There are no textbooks, notes, or computers allowed during exams.

Final grades will be assigned on a curve at the end of the course.


This schedule is subject to change.

All projects will be submitted on Blackboard unless otherwise noted.


All assignments will be submitted on Blackboard unless otherwise noted.


There will be readings listed for each day of class pertaining to the material we will cover, and I will expect that you have at least tried to read them (though it is okay if you do not understand everything right away!).

No textbook is required, but if you would like additional resources the following may be useful:


The Department of Computer Science expects and enforces the highest standards of academic integrity and ethics. The Department takes severe action against academic dishonesty, which may include failing grades on an assignment or in a course, up to a recommendation for dismissal from the University.

Academic dishonesty is defined as any action or practice that provides the potential for an unfair advantage to one individual or one group. Academic dishonesty includes misrepresenting facts, fabricating or doctoring data or results, representing another's work or knowledge as one's own, disrupting or destroying the work of others, or abetting anyone who engages in such practices.

Academic dishonesty is not absolute because the expectations for collaboration vary. In some courses, for example, students are assigned to work on team projects. In others, students are given permission to collaborate on homework projects or to have written materials present during an examination. Unless otherwise specified, however, the CS Department requires all work to be the result of individual effort, performed without the help of other individuals or outside sources. If a question arises about the type of external materials that may be used or the amount of collaboration that is permitted for a given task, each individual involved is responsible for verifying the rules with the appropriate authority before engaging in collaborative activities, using external materials, or accepting help from others.

A student accused of academic dishonesty must be afforded due process as defined by Purdue University procedures. The Dean of Students Office may be notified concerning an academic dishonesty incident as provided by Purdue University procedures.
