This two-day course is designed to provide an introduction to the Intrusion Prevention System (IPS) feature set available on the Juniper Networks SRX Series Services Gateway. The course covers concepts, ideas, and terminology relating to providing intrusion prevention using the SRX Series platform. Hands-on labs offer you the opportunity to configure various IPS features and to test and analyze those functions. This course is based on the Junos operating system Release 10.4R1.


This course benefits individuals responsible for configuring and monitoring the IPS aspects of SRX Series devices.
