Abstract
A storage device comprising a memory, a controller, and a host interface operative to connect with a host. The memory containing data locations access to which are controllable by a protection application which is executable on a host. When the host interface operatively coupled to a host data locations in the memory are accessible to an operating system of the host only under permission from the protection application. The controller communicates with the protection application running on the host for allowing the protection application access to data locations in the memory. Upon a host request for access to a data location, the controller determines if permission to access the requested data location is acquired from the protection application. The permission is based on determination of the protection application that the data location does not contain malicious data harmful to the host operating system, to any application and/or to any data on the host.
