Abstract
A security-enhanced network storage device. Apparatus and methods disclosed which allow network-connected client systems or groups of such systems to access data storage devices over the network in a highly secure fashion. Systems not having the appropriate permission are excluded from access. Characteristics of such a network attached storage device include the following: (1) Clients can only access the data they have been given permission to access, based on a combination of access control lists and physical system interconnects. (2) Client data access permissions in representative embodiments are stored and managed on the security-enhanced network attached storage device and are not accessible by clients, thereby improving data security. (4) Client access permissions can be checked on a per-IP-packet basis, so that all data transfers can be validated before they occurs, thus also, improving data security. (5) Clients interact with security-enhanced network attached devices in essentially the same manner with which they interact with traditional network-based file systems. (6) In addition, new individual client systems can be automatically given access to appropriate storage by adding them to the client grouping without having to update an access control list which is maintained in the security-enhanced network attached storage device.
