Abstract

A host system is configured to sequester protected data files to a separate data storage device. The host system includes an input device for receiving commands from a user, storage media for storing data files including the protected data files, a communication interface configured to communicate with the separate data storage device, and a network interface configured to communicate with a network server. The host system includes one or more processors configured, individually or in combination, to receive from the user, via the input device, a request to download a file from the network server. In response to determining that the file is a potential risk to the host system, the one or more processors are further configured, individually or in combination, to transfer the first subset of files to the separate data storage device and subsequent to transferring the first subset of files, complete downloading the file.
