Dear readers,

We present a new e-book, containing workshop materials from SNORT IDS BLAST COURSE. We would like to share them with those of you who do not participate in the course itself (we recommend you do that though). This e-book will be added to the course as a free download, for those of you who want to learn offline. All materials here were written by our wonderful instructor, Raymond Blockmon!

Enjoy!

Course Conclusion

COURSE DESCRIPTION:

In this course, we will use the Security Onion operating system. Security Onion is based on Ubuntu Linux distro. It contains the Snort IDS, Suricata, Bro, OSSEC, Sguil, Squert, ELSA, Xplico, NetworkMiner, and many other security tools. We will use the Snort IDS application  for the majority of this blast course.

The target learning objective for this course is to introduce the student with to the Snort IDS.  We will  learn how to setup IP and Port variables for ease of management followed by being acquainted with basic Snort rules. We will then move to define our own custom rules. Finally, we will advance our learning by crafting complex Snort rules to enhance our network IDS capabilities and streamline processing power. This course is streamlined for advanced users who wish to add to their knowledge about IDS capabilities using Snort.

The course session will last for three weeks, but the course is self-paced – you can learn when you want!
