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 a…
