The Target of Evaluation (TOE) is Juniper Networks, Inc. Junos OS 21.2R2 operating system on Services Gateway appliance SRX1500, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600 and SRX5800. The TOE can operate in single mode or in cluster mode, also known as high availability (HA). In cluster mode, a pair of devices are connected together and configured to operate like a single device to provide high availability. When configured as a chassis cluster, the two nodes back up each other, with one node acting as the primary device and the other as the secondary device, ensuring stateful failover of processes and services in the event of system or hardware failure. If the primary device fails, the secondary device takes over processing of traffic.
Each Juniper Networks SRX Services Gateway appliance is a security system that supports a variety of high-speed interfaces for medium/large networks and network applications. The appliances are physically self-contained. They house all software, firmware and hardware necessary to perform all functions. The hardware consists of two major components: the Services Gateway appliance itself and various interface cards or adaptors which allow the appliances to communicate with the different types of networks that may be required within the environment where the Services Gateway appliances are used.
The TOE also provides multi-site virtual private network (VPN) gateway functionality and implements Intrusion Prevention System functionality, capable of monitoring information flows to detect potential attacks based on pre-defined attack signatures and anomaly characteristics in the traffic.
