Course Goal / Objective
This course introduces the fundamental principles of computer and network security by studying attacks on computer systems and network. Students will learn how those attacks work and how to prevent them using a variety of security protocols, tools and architectures.
Course Content
Introduction to cryptography. Classification of threats, attackers and victims. Wireless security: WEP, WPA and WPA-2. Jamming attack detection and mitigation in wireless networks. Virtual private networks and tunneling. IPSec. SSL/TLS. SSH. Chip cards and RFID security. AAA protocols: Kerberos, Radius, TACACS. Secure E-Payment and iKP protocol family. Firewalls and intrusion detection systems. Model checking methods for security protocols.
Course Precondition
There are no prerequisites.
