Abstract:
1. A computer-implemented method for applying data loss prevention policies to closed-storage portable devices, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: injecting, into at least one application process running on the computing device, a data loss prevention component that monitors Application Programming Interface (API) calls used by the application process; intercepting, via the data loss prevention component that monitors API calls used by the application process, an attempt by the application process to transfer a file by calling an API that facilitates transferring the file from the computing device to a closed-storage portable device that is connected to the computing device via a closed-storage protocol, wherein the closed-storage portable device contains an internally managed file system that is not accessible to the computing device; identifying a data loss prevention policy that applies to the attempt by the application process to transfer the file; determining that the attempt by the application process to transfer the file violates the data loss prevention policy; performing a security action in response to determining that the attempt by the application process to transfer the file violates the data loss prevention policy.
