SEC503: Intrusion Detection In-Depth Waitlist

The materials were excellent! Well done, best materials I have used in years!

Joe Hernandez, Key Bank

This course provides a good basis of knowledge and presents important tools which will be at the core of any intrusion analysis.

Thomas Kelly, DIA

Learn practical hands-on intrusion detection and traffic analysis from top practitioners/authors in the field. This challenging track methodically progresses from understanding the theory of TCP/IP, examining packets, using Snort to analyze traffic, becoming familiar with the tools and techniques for traffic and intrusion analysis, to reinforcing what you've learned with a hands-on challenge of investigating an incident. Students should be able to "hit the ground running" once returning to a live environment where traffic analysis it required.

This is a fast-paced course, and students are expected to have a basic working knowledge of TCP/IP in order to fully understand the topics that will be discussed. Although others may benefit from this course, it is most appropriate for students who are or who will become intrusion detection/prevention analysts. Students generally range from novices with some TCP/IP background all the way to seasoned analysts. The challenging hands-on exercises are specially designed to be valuable for all experience levels. We strongly recommend that you spend some time getting familiar with tcpdump before coming to class.

Overview

This day is the culmination and consummation of all the previous days where you use your knowledge for a hands-on exercise to investigate an actual attack. This is a guided approach of discovering the network architecture, profiling traffic, identifying attacks, analyzing possible compromises, characterizing the enemy, tracking the hacker's activities, and correlation.

This engaging activity allows you to work with a team or individually to reinforce what you've learned and challenge you to think analytically.

Note: This course is available to Security 503 participants only.

Author Statement

When I was invited to be a member of a computer incident response team in the late 1990's (just after Al Gore invented the Internet), there was no formal cybersecurity training available. Consequently, I learned on the job and made my share, and then some, of mistakes. I was so naive that I tried to report an attack on our network by a host with an IP address in the 192.168 reserved private network, available for use by anyone. Needless to say, I got a very embarrassing enlightenment when someone clued me in.

With the benefit of experience and the passage of time, there are many lessons to be shared with you. This knowledge affords you the opportunity to learn and practice in the classroom to prepare you for the fast-paced always-interesting job of intrusion detection analysts.
