Introduction to Snort


The outline/syllabus for the course is as follows;

This three (3) day course is designed to introduce the IT security professional to the world's most effective and widely used Intrusion Detection System (IDS), Snort. When the students complete the course they will have;


    (1) a fundamental understanding of the inner architecture of Snort;


    (2) an ability to write their own custom Snort rules;


    (3) configure Snort to output its alerts to a database for further analysis


    (4) tune Snort for optimal performance


    (5) how to install and configure Snort as an effective IDS/IPS


    (6) choose an appropriate GUI interface for analysis


This course will be taught with hands-on labs using Snort in a Debian Linux environment.



Target Audience:


This course is designed for network administrators, security administrators, security consultants, and

other security professionals. Even those using other manufacturer's IDS's will gain from this course as it

will convey the basic inner workings of any IDS.




Although there are no prerequisites for this course, we have found that those with a solid understanding of TCP/IP protocol structure and Linux/Unix gain the most from the course. For those without this background, we spend part of the first day introducing these concepts and techniques to give the student adequate knowledge to complete the course.
