Abstract: A method comprises receiving, by a shim application of a user equipment (UE), an outbound communication from a first application destined for an external device, prior to transmitting the outbound communication to the external device, determining, by the shim application, whether to forward the outbound communication to the external device, via a radio interface of the UE, based on a first policy, receiving, by the shim application, an inbound communication destined for a second application from the external device, via the radio interface, determining, by the shim application, whether to forward the inbound communication to the second application based on a second policy, receiving, by the shim application, an inter-enclave communication from the first application destined for the second application, and determining, by the shim application, whether to forward the inter-enclave communication to the second application based on the second policy.
