  • Introduction to the Junos Operating System (IJOS)
  • Junos Routing Essentials (JRE)
  • Junos Security (JSEC)

Course Description:

In this course, you will go deeper into Junos security with advanced coverage of IPsec deployments, virtualization, high availability, advanced Network Address Translation (NAT) deployments, and Layer 2 security with Juniper Networks SRX Series Services Gateways. Through demonstrations and hands-on labs, you will gain experience configuring and monitoring advanced security features of the Junos operating system.

  • Configure, utilize, and monitor the various interface types available to the SRX Series product line
  • Junos OS processing of Application Layer Gateways (ALGs)
  • Alter the Junos default behavior of ALG and application processing
  • Implement address books with dynamic addressing
  • Compose security policies utilizing ALGs, custom applications, and dynamic addressing for various scenarios
  • Junos debugging tools to analyze traffic flows and identify traffic processing patterns and problems
  • Junos routing instance types used for virtualization
  • Implement virtual routing instances
  • Configure route sharing between routing instances using logical tunnel interfaces
  • Implement selective packet-based forwarding
  • Implement filter-based forwarding
  • Implement static, source, destination, and dual NAT in complex LAN environments
  • Implement variations of cone or persistent NAT
  • Interaction between NAT and security policy
  • Implement optimized chassis clustering
  • IP version 6 (IPv6) support for chassis clusters
  • Differentiate and configure standard point-to-point IP Security (IPsec) virtual private network (VPN) tunnels, hub-and-spoke VPNs, dynamic VPNs, and group VPNs
  • Implement OSPF over IPsec tunnels and utilize generic routing encapsulation (GRE) to interconnect to legacy firewalls
  • Monitor the operations of the various IPsec VPN implementations
  • Public key cryptography for certificates
  • Junos tools for troubleshooting Junos security implementations
  • Perform successful troubleshooting of some common Junos security issues
