This five-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, you will gain experience in configuring and monitoring the advanced Junos OS security features with advanced coverage of virtualization, AppSecure, advanced Network Address Translation (NAT) deployments, Layer 2 security, and Sky ATP. This course uses Juniper Networks SRX Series Services Gateways for the hands-on component.
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.
- Describe Junos security handling at Layer 2 versus Layer 3.
- Describe the placement and traffic distribution of the various components of SRX devices.
- Configure, utilize, and monitor the various interface types available to the SRX Series product line.
- Describe 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.
- 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.
- Implement selective packet-based forwarding.
- Implement filter-based forwarding.
- Describe and implement static, source, destination, and dual NAT in complex LAN environments.
- Describe and implement variations of cone, or persistent NAT.
- Describe the interaction between NAT and security policy.
- Implement optimized chassis clustering.
- Describe 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.
- Describe public key cryptography for certificates.
- Utilize Junos tools for troubleshooting Junos security implementations.
- Perform successful troubleshooting of some common Junos security issues.
This course benefits individuals responsible for implementing, monitoring, and troubleshooting Junos security components.
AJSEC is an advanced-level course.
Students should have a strong level of TCP/IP networking and security knowledge. Students should also attend the Introduction to the Junos Operating System (IJOS), Junos Routing Essentials (JRE), and Junos Security (JSEC) courses prior to attending this class.
