This course is designed for technical professionals who need to know how to deploy open source intrusion detection systems (IDS) and intrusion prevention systems (IPS), and write Snort rules.
Securing Cisco Networks with Open Source Snort is a lab-intensive course that introduces students to the open source Snort technology as well as rule writing. You will learn how to build and manage a Snort system using open source tools, plug-ins and the Snort rule language to help manage, tune, and deliver feedback on suspicious network activity.This course combines lecture materials and hands-on labs throughout to make sure that you are able to construct a solid, secure Snort installation and write Snort rules using proper syntax and structure.
