The two steps that will fulfill the requirement of deploying a security policy on an SRX Series device that blocks all known Tor network IP addresses are enrolling the devices with Juniper ATP Cloud and enabling a third-party Tor feed. Juniper ATP Cloud is a cloud-based service that provides advanced threat detection and mitigation capabilities for SRX Series devices. By enrolling the devices with Juniper ATP Cloud, the devices can leverage the cloud intelligence and analytics to identify and block malicious traffic, including Tor traffic. A third-party Tor feed is a source of information that provides a list of IP addresses that are associated with the Tor network. By enabling a third-party Tor feed on the SRX Series device, the device can use the feed to create a dynamic address object that contains all the known Tor IP addresses. The device can then apply a security policy that denies traffic from or to the dynamic address object, effectively blocking the Tor network IP addresses.
