The Target of Evaluation (TOE) is Juniper Networks, Inc. Junos OS 20.2R1 Services Gateway appliances SRX345, SRX345-DUAL-AC, SRX380 and SRX1500 SRX380.
The Services Gateway appliances primarily support the definition of, and enforce, information flow policies among network nodes. The Services Gateway appliances provide for stateful inspection of every packet that traverses the network and provide central management to manage the network security policy. All information flow from one network node to another passes through an instance of the TOE. Information flow is controlled on the basis of network node addresses, protocol, type of access requested, and services requested. In support of the information flow security functions, the TOE ensures that security-relevant activity is audited, that their own functions are protected from potential attacks, and provides the security tools to manage all of the security functions. The TOE provides multi-site Virtual Private Network (VPN) gateway functionality.
The TOE also implements Intrusion Prevention System functionality, capable of monitoring information flows to detect potential attacks based on pre-defined attack signature and anomaly characteristics in the traffic.
