To help stop application level attacks from penetrating and proliferating across the network, Juniper Networks firewalls integrate intrusion prevention technology in the form of a Deep Inspection firewall. Leveraging the efficiencies of both Stateful inspection and IPS technologies, Juniper Networks Deep Inspection firewall can efficiently perform network security functions as well as analysis on the application message to determine whether to accept or deny traffic. Juniper Networks IPS technology applies a deeper level of application understanding to the traffic to make access control decisions based on the intent of that traffic. Deployed at the perimeter, a Juniper Networks Deep Inspection firewall focuses on preventing application-level attacks aimed at commonly used protocols. As a true IPS, Deep Inspection eliminates application-level ambiguities, performing de-fragmentation, reassembly, scrubbing and normalization, to convert network packets to the application-level message being transferred between t
