Abstract: A system and method for isolating secure communication events from a non-secure application are described herein. The method can include the steps of intercepting a communication event from an external communications network or an external communications device and determining whether the communication event is a secure communication event. If the communication event is a secure communication event, the secure communication event can be processed by a secure application. In addition, the secure communication event can be prevented from being processed by the non-secure application.

Abstract: A method and system of runtime injection for a secure application are described herein. During runtime of the secure application, a conventional request from the secure application can be intercepted. The intercepted conventional request can be modified such that the request is unrecognizable to an unsecure application, which can create a secure request. In addition, the secure request can be passed to a system process to enable the system process to process the secure request.

Abstract: A method and system of selectively permitting a non-secure application to communicate with a secure application are described herein. The method can be practiced in a system that support an environment designed to restrict secure applications from processing requests from non-secure applications. In particular, a request can be received from a non-secure application by a system framework and, through the system framework, it can be determined that a secure application is capable of processing the request. The request can be delegated from the system framework to a secure framework. In addition, through the secure framework, it can be determined whether the non-secure application is an authorized non-secure application. If the non-secure application is an authorized non-secure application, the secure application can be permitted to process the request from the non-secure application.

Abstract: A method and system for selective application of device policies are described herein. The method can include the step of receiving one or more policies from a messaging server in which the policies are intended to be indiscriminately applied to a computing device. Out of the received policies, one or more container policies that are to be applied to a container of the computing device can be identified. The identified container policies can be applied to the container such that the identified container policies may be prevented from being indiscriminately applied to the computing device.

Abstract: A system and method for linking to a shared library, such as a shared class library, are described herein. The method can include the step of launching an application on a computing device in which the computing device supports a first class loader and a second class loader. The first class loader may serve as a parent class loader to the second class loader. In response to the launching of the application, an override class loader that is configured to serve as an override parent class loader to the second class loader can be generated. When a request for a component is received from the launched application at the second class loader, the request can be intercepted by the override class loader to determine if the override class loader is to process the request. If the override class loader is to process the request, the override class loader can be used to search the shared library for the component.
