JN0-335 Exam Dumps : Security, Specialist (JNCIS-SEC)

 The show security policies policy-name detail command shows policy counters for a configured policy. Policy counters display the number of packets and bytes that match the policy, as well as the number of sessions that are created, denied, or closed by the policy. Policy counters can help monitor and troubleshoot the traffic flow and security policy enforcement on the SRX firewall1.

The show security policies policy-name detail command does not display details about the default security policy, which is the implicit policy that is applied when no other policy matches the traffic. The default security policy can be viewed by using the show security policies default-policy command2.

The show security policies policy-name detail command does not identify the different custom policies enabled, which are the user-defined policies that specify the action and conditions for the traffic between zones. The custom policies can be viewed by using the show security policies command without any options1.

The show security policies policy-name detail command does not show the system log files for the local SRX Series device, which are the files that record the events and messages generated by the device. The system log files can be viewed by using the show log command with the name of the file3. References:

= The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor for delivering security services that scale to match network demand. The vSRX supports Juniper Contrail Networking and third-party software-defined networking (SDN) solutions, which enable dynamic and automated network provisioning and management. The vSRX also integrates with cloud orchestration tools such as OpenStack, which allow for flexible deployment and configuration of virtual machines and networks. The vSRX provides granular security for the workloads that run within the virtual network on the public or private cloud. It supports next-generation firewall capabilities, such as application security, intrusion prevention, user identity, and role-based access control. It also supports advanced threat prevention features, such as malware sandboxing, threat intelligence feeds, and encrypted traffic inspection. The vSRX can protect the network from both internal and external threats, and enforce consistent security policies across the entire network. References:

SRX does not identify the iot device. It streams the metadata to Juniper ATP cloud and Junipe ATP cloud identifies the device.
