SRX Series device chassis clusters are created by physically connecting two identical cluster-supported SRX Series devices using a pair of the same type of Ethernet connections. The connection is made for both a control link and a fabric (data) link between the two devices. The chassis cluster data plane is connected with revenue ports, which are the ports that carry user traffic. The chassis cluster can contain a maximum of two devices, as only two nodes can form a cluster. The chassis cluster data plane is not connected with SPC ports, which are the ports that provide services processing. The chassis cluster cannot contain more than two devices, as this would violate the cluster design. References: Chassis Cluster Overview, Connecting SRX Series Firewalls to Create a Chassis Cluster

SSL proxy is a feature that allows SRX Series devices to act as an intermediary between the client and the server for SSL/TLS encrypted traffic. SRX Series devices support two types of SSL proxy: SSL forward proxy and SSL reverse proxy. SSL forward proxy is also known as web proxy or client-protection, and SSL reverse proxy is also known as server-protection1.

SSL forward proxy enables the SRX Series device to decrypt the client-side traffic and apply security policies before re-encrypting and forwarding it to the server. This allows the SRX Series device to inspect the application data and identify the applications and threats in the encrypted traffic2.

SSL reverse proxy enables the SRX Series device to decrypt the server-side traffic and apply security policies before re-encrypting and forwarding it to the client. This allows the SRX Series device to protect the server from malicious clients and provide load balancing and high availability for the server3.

The infected host cloud feed is a list of IP addresses that have been identified as compromised or infected by malware. The feed is updated by Juniper ATP Cloud based on the detection of malicious activity from the hosts, such as contacting known command-and-control servers. When a host on the network reaches the configured threat level threshold, its IP address is automatically added to the infected host cloud feed and blocked from communicating with any other hosts on the Internet. The other feeds are not relevant for this situation. The command-and-control cloud feed is a list of IP addresses that are known to be used by malware for remote control and communication. The allowlist and blocklist feed is a user-defined list of IP addresses that are either allowed or denied by the SRX Series device. The custom cloud feed is a user-defined list of IP addresses that are associated with a specific category or threat level. References:
