Abstract
Access to devices can be controlled dynamically. A device control driver can function as an upper filter driver so that it can intercept I/O requests that target a particular device. The device control driver can be configured to communicate with a device control server to dynamically determine whether the current user is allowed to access the particular device. The device control server can employ policy or administrator input to determine whether access should be allowed and can then notify the device control driver accordingly. When access is granted, the device control driver can pass I/O requests down the device driver stack. Otherwise, the device control driver can block the I/O requests. Also, when access is granted, the device control server can specify a permission expiration time after which the device control driver should again resume blocking I/O requests.
