You plan to use unified security policies to identify and control nested HTTP applications.

Unified security policies use AppID to classify and control applications based on Layer 7 inspection, including applications nested within trusted services such as HTTP. Juniper documentation states that AppID identifies dynamic or real-time Layer 4 through Layer 7 applications and that dynamic applications can be added to unified security policy match criteria. To use AppID-based control, the SRX must have the required Application Identification feature license and application signature support. Dynamic application objects must then be referenced in the security policy so the firewall can match traffic by application identity rather than only by port or protocol. Unified policies do not have to be created only in the global zone, and disabling the default policy is not required.
