International Classification:

G06F 15/18

US Classification:

726 23, 726 26

Abstract:

An intrusion tolerant communication network and related methods is provided that places emphasis on continuity of operation and provides for an attack-survivable communication network whose network devices collectively accomplish the specified networking intent even under attack and despite active intrusions. The present invention defines methods for network intrusion tolerance in terms of the various state transitions that maximize the overall effectiveness of an intrusion tolerant communication network.

International Classification:

G06F011/30

US Classification:

713/201000

Abstract:

The invention relates to a reconfigurable scalable intrusion-tolerant network that is interposed between a service requesting client and a protected server to minimize the impact of intrusive events. The apparatus may include a proxy server for receiving the requests from a client and forwarding them to a protected server. Acceptance monitors receive the response from a protected server and apply one or more acceptance tests. A ballot monitor receives the result of the acceptance tests and determines a response to the client. The network may also include an intrusion sensor to detect threats to the network and a reconfigurer to alter the network forwarding scheme. Reconfiguration may include isolating network elements, creating parallel paths, implementing redundant operations, or assessing the validity of responses.

International Classification:

G06F 12/02

US Classification:

711103, 711E12008

Abstract:

An optimized redundant array of solid state devices may include an array of one or more optimized solid-state devices and a controller coupled to the solid-state devices for managing the solid-state devices. The controller may be configured to globally coordinate the garbage collection activities of each of said optimized solid-state devices, for instance, to minimize the degraded performance time and increase the optimal performance time of the entire array of devices.
