The Securing Cisco Networks with Open Source Snort(SSFSNORT) course shows you how to deploy Snort®in small to enterprise-scale implementations.

You will learn how to install, configure, and operate Snort in Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) modes. You’ll practice installing and configuring Snort, utilize additional software tools and define rules to configure and improve the Snort environment, and more

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. This course prepares you to take the Securing Cisco Networks with Open Source Snort exam (exam ID 500-280).
