AbstractSome of today's most damaging attacks on computer systems involve
exploitation of network infrastructure, either as the target of attack
or as a vehicle to attack end systems. This course provides an
in-depth study of network attack techniques and methods to defend
against them.
Objective- Students are familiar with fundamental network security concepts.
- Students can assess current threats that Internet services and networked devices face, and can evaluate appropriate countermeasures.
- Students can identify and assess known vulnerabilities in a software system that is connected to the Internet (through analysis and penetration testing tools).
- Students have an in-depth understanding of a range of important security technologies.
- Students learn how formal analysis techniques can help in the design of secure networked systems.
ContentThe course will cover topics spanning five broad themes: (1) network
defense mechanisms such as secure routing protocols, TLS, anonymous
communication systems, network intrusion detection systems, and
public-key infrastructures; (2) network attacks such as denial of
service (DoS) and distributed denial-of-service (DDoS) attacks; (3)
analysis and inference topics such as network forensics and attack
economics; (4) formal analysis techniques for verifying the security
properties of network architectures; and (5) new technologies related
to next-generation networks.
Prerequisites / NoticeThis lecture is intended for students with an interest in securing
Internet communication services and network devices. Students are
assumed to have knowledge in networking as taught in a Communication
Networks lecture. The course will involve a course project and some
smaller programming projects as part of the homework. Students are
expected to have basic knowledge in network programming in a
programming language such as C/C++, Go, or Python.
