Start your journey to becoming a Network Security Guru.

This extremely popular class focuses on network security, and makes an excellent companion class to the GL550: Host Security course. Protocols used in Linux, UNIX, and Windows 2000 are examined. After a detailed discussion of the TCP/IP suite component protocols and ethernet operation, the student practices using various tools to capture, analyze, and generate IP traffic. Students then explore the tools and techniques used to exploit protocol weaknesses and perform more advanced network attacks. After building a thorough understanding of network based attacks, course focus shifts to the defensive solutions available. Students install, configure, and test two of the most popular and powerful NIDS solutions available. Finally, students create a Linux based router / firewall solution, including advanced functionality such as NAT, policy routing, and traffic shaping.
