Abstract
An external security device is provided in the communication path between devices of different security levels. A higher security device needs only to trust the security of the external device, rather than relying on operating system and file system software that cannot be assured. The external security device blocks access requests that may be using covert channels, but returns status information that indicates that the request is successful. The external security device may then audit access requests to provide a higher level of accountability. The external security device also handles data duplication to prevent or significantly reduce the threat of traffic analysis.
