Securing Cisco Networks with Open Source Snort - SSFSNORT Course Outline

(4 Days)

Overview

In this four-day course, Securing Cisco Networks with Open Source Snort®, students will learn how to build and manage a Snort® system using open source tools, plug-ins, as well as the Snort® rule language to help manage, tune, and deliver feedback on suspicious network activity.

This lab-intensive course introduces you to the open source Snort®technology, as well as rule writing. Among other powerful features, you become familiar with:

  • How to build and manage a Snort®system
  • How to update rules
  • Snort®rules language
  • The capabilities of Snort®when deployed passively and inline

The course begins by introducing the Snort®technology and progresses through the installation and operation of Snort®. You 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 you practice in deploying and managing Snort®.
