ABOUT THE COURSE:

Communication networks are being extensively used by a large number of users for various applications(e.g., email, web browsing, Internet telephony, financial transactions). However, malicious or hostile users seek to attack networks by stealing secret information (e.g., passwords, credit card information), installing malware, disrupting communications, etc. The goals of the field of network security are to understand how malicious users can attack networks, and design mechanisms for defending networks against such attacks. The objective of the proposed course “Network Security” is to provide a detailed exposure to this important field to students. The course will include hands-on demonstration sessions.

INTENDED AUDIENCE: Students, faculty members, and industry practitioners in Electrical Engineering and Computer Science

PREREQUISITES:An understanding of the basics of computer networking and programming.

INDUSTRY SUPPORT: Companies that work in Information Technology (IT) and Security
