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 from being applicable to other Juniper hardware platforms running the Junos OS. This course is based on Junos OS Release 12.1R1.9.
AJSEC is an advanced-level course.
After successfully completing this course, you should be able to:
- Demonstrate understanding of concepts covered in the prerequisite Junos Security course.
- Describe the various forms of security supported by the Junos OS.
- Implement features of the AppSecure suite, including AppID, AppFW, and AppTrack.
- Configure custom application signatures.
- Describe Junos security handling at Layer 2 versus Layer 3.
- Implement Layer 2 transparent mode security features.
- Demonstrate understanding of Logical Systems (LSYS).
- Implement address books with dynamic addressing.
- Compose security policies utilizing ALGs, custom applications, and dynamic addressing for various scenarios.
- Use Junos debugging tools to analyze traffic flows and identify traffic processing patterns and problems.
- Describe Junos routing instance types used for virtualization.
- Implement virtual routing instances.
- Describe and configure route sharing between routing instances using logical tunnel interfaces.
- Describe and implement static, source, destination, and dual NAT in complex LAN environments.
- Describe and implement variations of persistent NAT.
- Describe and implement Carrier Grade NAT (CGN) solutions for IPv6 NAT, such as NAT64, NAT46, and DS-Lite.
- Describe the interaction between NAT and security policy.
- Demonstrate understanding of DNS doctoring.
- 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 IPsec tunnels using virtual routers.
- 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.
- Describe public key cryptography for certificates.
- Utilize Junos tools for troubleshooting Junos security implementations.
- Perform successful troubleshooting of some common Junos security issues.
