According to one embodiment, in response to a request received from an application by a launch module hosted by an operating system and executed by a processor to dynamically load a library, a library validation module hosted by the operating system extracts a first team identifier (ID) from the application, where the first team ID identifies an application provider that provides the application. The library validation module extracts a second team ID from the library, where the second team ID identifies a library provider that provides the library. The first team ID and the second team ID are compared to determine whether the first team ID matches the second team ID. In response to determining that the first team ID matches the second team ID, the launch module launches the library to allow the application communicate with the library; otherwise, the request is denied.
