Introductory course on computer security with the objective to introduce concepts and principles of computer systems security. Notions of security, basic cryptographic primitives and their application, basics of authentication and access control, basics of key-management, basics of malware and software security.


What CS 372 is about

The theme of CS 372 is “How Computer Networks Work”.  We will begin with an overview of the basic concepts of networking technologies.  We will then delve deeper into these concepts by exploring networking functionality at each of the layers of the Internet Protocol Stack.  Along the way, we will learn about the hardware and software that enable network communication, the protocols that control network communication, and some of the applications that make it possible for the general public to use and enjoy the Internet.

Computer networking is complicated.  There is an enormous body of knowledge that encompasses multiple areas of specialization.  We will attempt to handle the complexity by concentrating on theory, abstractions, and general concepts, and then using a few example technologies to illustrate the concepts.  In addition, we will have some hands-on lab experience to reinforce the concepts.

CS 372 is an introduction to computer networking.  As such, we chose a mostly theoretical approach to the materials, with some hands-on lab and programming work.  It offers an overview of several aspects of networking (breadth), with details about a few networking technologies (depth).  It can be a first step in earning certification in networking.

CS 372 is not a network administration course.  It is not a certification course in any area of specialization.  Additional courses are required in order to qualify for a CNA/CNE or other networking or systems administration professional certifications.

The university catalog description for CS 372 is:

"Computer network principles, fundamental networking concepts, packet-switching and circuit switching, TCP/IP protocol layers, reliable data transfer, congestion control, flow control, packet forwarding and routing, MAC addressing, multiple access techniques."

The prerequisites for this course are CS 261 and CS 271 or equivalents.


Oregon State University does have a System Administration course available, CS312, but only currently in an on-campus offering (although, depending on the instructor, the course can be completed entirely remotely).

Communication Policy

Please post all course-related questions in the Ed Discussions discussion boards so that the whole class may benefit from our conversations.  Not all posts require a reply from the instructor or learning assistants and often it is better for students to work on an answer to a question themselves, helping cement understanding or locate resources to answer questions.

To contact the learning assistants, open Canvas Inbox, compose a new message, select this course, then next to the ‘To’ box click the address book, select “Teaching Assistants”, then choose the name(s) of learning assistants you wish to contact.

Please DM in Teams or email the instructor only for matters of a personal or private (grading) nature.  The instructor or a learning assistant will reply to most course-related questions within 48 hours.

If there are questions about grading, please contact your assigned grader first but feel free to reach out to an instructor directly if there are still questions afterward.

Office Hours

The best place to ask questions and get help is on Ed discussions or Teams. If you'd like direct, personal help, our Office Hours for this course will be held on our Teams channel or on Zoom. The up to date list of office hours is provided on the Home page.

Note: Office hours will not be held during Finals Week, or on days that the University has off (holidays, inclement weather days, etc.). The Instructors and TAs reserve the right to cancel or move office hours, but will give appropriate warning, if possible.
