The Target of Evaluation (TOE) is Juniper Networks, Inc. Junos OS 18.1R1 executing on QFX5100 and EX4600 Ethernet Switches.
Each of the Ethernet Switches is a secure network device that protects itself largely by offering only a minimal logical interface to the network and attached nodes. All switching platforms are powered by the Junos OS software, Junos OS 18.1R1, which is a special purpose OS that provides no general purpose computing capability. Junos OS provides both management and control functions as well as all IP switching.
The Ethernet Switches primarily support the definition of, and enforce, information flow policies among network nodes. 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 and protocol. In support of the information flow security functions, the TOE ensures that security-relevant activity is audited, and provides the security tools to manage all of the security functions.
