LNX510 - Network Security
Course description
This popular class focuses on network security. 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.
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 in comprehension. This is an intense class that covers many topics. If you are unsure if you meet the prerequisites, please speak with a Guru Labs' representative.
