CS6501/ECE6502: Network Security and Privacy, Spring 2024

Course Description

This course investigates security and privacy issues that stem from the Internet infrastructure. We will cover topics such as BGP security, DNS security, DDoS attacks, and anonymous communications. We will also look at various mechanisms to secure the Internet infrastructure as well as privacy enhancing technologies. Note that this course will involve literature review and paper presentation/discussion.


No formal prerequisites, but assumes basic familiarity with programming in languages like C and Python. Some background in computer networks (e.g., equivalence of CS4457) will be helpful.

Academic Integrity

Please also read the course syllabus carefully for additional information

No plagiarism

You must cite any and every source you consult, other than those explicitly provided by the course itself. This includes talking with a friend/classmate or looking at a website/book. If you're unsure, please ask us. We run all submissions through a plagiarism checker by default.

Write your own code and DO NOT share your code

All assignments are individual work and there is no collaboration allowed. That means you should not push it to GitHub (or any other site), send a copy to anyone, turn your screen to your neighbor, code up solutions together, etc. It is ok to discuss with classmates, but please include the names of students whom you've discussed with.

Consequences of dishonesty

Penalties may be up to and including a failing grade (F) in the course, independent of and in addition to the operations of the Honor Code.
