Course Description:
The SSFSNORT - Securing Cisco Networks with Open Source Snort course is a 4-day lab-intensive course that is designed to introduce students to the open source Snort technology, as well as rule writing. Among other powerful features, students will become familiar with:?
- Building and Managing a Snort system
- Updating rules
- Snort rules language
- The capabilities of Snort when deployed passively and inline?
The course with an introduction to the Snort technology and progresses through the installation and operation of Snort. Students will discover the various output types that Snort provides and learn about automated rule management including how to deploy and configure Pulled Pork, inline operations, and how to create custom Snort rules, including advanced rule-writing techniques and OpenAppID.
This course combines lecture materials and hands-on labs that give students practice in deploying and managing Snort.
Topics covered in the course include:
- Snort technology and identify the resources that are available for maintaining a Snort deployment
- Installing Snort on a Linux-based operating system

Testimonials
This was the class I needed.
The instructor Jeff took his time and made sure we understood each topic before moving to the next. He answered all of our questions, and I don't know about the rest of the students, but was very pleased with this experience.
I finally understand how to use Excel.
-Amanda T (Yale New Haven Hospital).
Great class!
We were able to cover a lot of information in one day without getting overwhelmed.
