Logical Systems Overview

Starting in Security Director Release 18.2R1, you can create logical systems in Security Director. Logical systems for SRX Series devices enable you to partition a single device into secure contexts. Each logical system has its own discrete administrative domain, logical interfaces, routing instances, security firewall and other security features. By transforming an SRX Series device into a multitenant logical systems device, you can give various departments, organizations, customers, and partners—depending on your environment—private use of portions of its resources and a private view of the device.

To distribute security resources across logical systems, you can create security profiles that specify the type and amount of resources to be allocated to a logical system. After creating security profiles, you can bind them to logical systems. The logical systems are defined largely by the resources allocated to them, including security components, interfaces, routing instances, static routes, and dynamic routing protocols. You cannot create a logical system without assigning a security profile to it. You can configure a single security profile to assign resources to a specific logical system or use the same security profile for more than one logical system.
