This extremely popular class focuses on network
security, and makes an excellent companion class to the
GL550: Enterprise
Linux Security Administration course.
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 one 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.
Prerequisites: Since the tools used in class are compiled and run on a
Linux system, Linux or UNIX system experience is helpful, but not
necessary. A solid background in networking concepts will greatly aid
incomprehension. This is an intense class that covers many topics.
