Junos Security

Course Overview

This five-day course covers the configuration, operation, and implementation of SRX Series Services Gateways in a typical network environment. Key topics within this course include: security zones, security policies, Network Address Translation (NAT), IPsec VPNs, and chassis clustering. Through demonstrations and hands-on labs, students will gain experience in configuring the Junos OS and monitoring device operations of Junos security devices. This course uses Juniper Networks SRX Series Services Gateways for the primary hands-on component. This course is based on Junos OS Release 17.4R1.16 and the vSRX virtual appliance.

Target Audience

This course benefits operators of SRX Series devices. These operators include network engineers, administrators, support personnel, and reseller support personnel.
