Advanced Junos Security (AJSEC) 高级Junos安全性
 

This three-day course, which is designed to build off of the current Junos Security (JSEC) offering, delves deeper into Junos security. Through demonstrations and hands-on labs, students gain experience in configuring and monitoring the advanced Junos operating system security features with advanced coverage of IPsec deployments, virtualization, AppSecure, advanced Network Address Translation (NAT) deployments, and Layer 2 security. This course uses Juniper Networks SRX Series Services Gateways for the hands-on component, but the lab environment does not preclude the course frombeing applicable to other Juniper hardware platforms running the Junos OS. This course is based on Junos OS Release 12.1R1.9.
