ISA656: Network Security
George Mason University, Computer Science, Fall 2016
Instructor: Prof. Foteini Baldimtsi (foteini@gmu.edu)
Office Hours: Mondays 2:00PM-4:00PM, Engineering 5333 (also by appointment)
Lectures: Mondays 4:30PM-7:10PM, Location: Innovation Hall 136
Course Summary
An in-depth introduction to the theory and practice of network security. It assumes basic knowledge of cryptography and its applications in modern network protocols. This course will train you how to "think like an adversary"---thinking about how adversary might attack a system by subverting and exploiting assumptions made during system design---and will discuss threat modeling and formal cryptographic approaches to defining and proving security or privacy.
The class provides deep coverage of widely used network security protocols such as SSL, TLS, SSH, Kerberos, IPSec, IKE, and PGP. It covers countermeasures to distributed denial of service attacks, security of routing protocols and the Domain Name System, e-mail security and spam countermeasures, wireless security, web security, trust negotiation and decentralized payment systems (Bitcoin like).
Prerequisites: ISA 562 and ISA 612 or CS 555; or permission of instructor. There will be substantial programming involved in the assignments, and students should be familiar with programming in C, Java or another language.
Required Materials
Text Book: Kaufman, Perlman, and Speciner. Network Security: Private Communication in a Public World, Second Edition, Prentice Hall PTR, 2002, ISBN 0130460192. (Required).
There will also be on-line news articles and research publications that will be required reading before some of the lectures.
Grading
Midterm: 25%
Labs: 5% (There will 2-3 in class labs)
Assignments: 40% (4 assignments that will require both programming and problem solving)
Final Project: 25% (You will work on project in network security with a writeup/presentation due at the end)
Class/Forum Participation: 5%
Assignments received later that day lose 5%, the next day 20%, two days late 40%, after that no credit will be given.
Communications: We will use piazza to communicate with you. You are welcome to use Piazza to set up study groups, to post interesting security incidents you read about (please tag these as "interesting incident in the news"), or to discuss the course with other students. If you have a question about the course you should: (a) Come to office hours, OR (b) Post to Piazza. You are welcome to post to Piazza anonymously, but please don't use private posts to ask technical questions. The rest of the class is probably also interested in your question, so make it public!
Ethics: To defend a system you need to be able to think like an attacker, and that includes understanding techniques that can be used to compromise security. However, using those techniques in the real world may violate the law or the university's rules, and it may be unethical. Under some circumstances, even probing for weaknesses may result in severe penalties, up to and including expulsion, civil fines, and jail time. Our policy is that you must respect the privacy and property rights of others at all times, or else you will fail the course.
Acting lawfully and ethically is your responsibility. Carefully read the Computer Fraud and Abuse Act (CFAA), a federal statute that broadly criminalizes computer intrusion. This is one of several laws that govern "hacking". Understand what this law prohibits.
