The goal of this course is to introduce challenges in securing computer systems and networks. We will discuss various types of vulnerabilities in existing software interfaces, such as buffer overflows, unsafe libc functions, filesystem design issues, etc. We will also discuss modernday defenses against attacks exploiting these vulnerabilities. In network security, we will discuss security problems in network protocols and routing, such as sniffing, denial of service, viruses, worms, and defenses against them. The course will involve reading research papers on relevant topics, programming assignments, and projects.The course is intended for senior undergraduates and first year graduate students.


The course requires an understanding of operating systems, networking protocols, and a basic understanding of programming languages.

Pre-requisites: CSL374 / CSL672 or equivalent, CSL373 / CSL633 or equivalent
