JSEC – Junos Security
5 days  (Instructor Led Online)  |  Junos Security

Course Details

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
