Abstract: A cloud-based platform encrypts data imported from an organization using respective data encryption keys (DEK). The platform prevents decrypted data of the organization, and the DEK(s) used to encrypt such data, from being persistently retained within the platform. Access to the DEK may be controlled by the organization. Accordingly, the organization may retain control over access to its data, after the data has been exported to the platform. The platform may provide a purge control by which the organization can configure the platform the purge any cached DEK and/or unencrypted data pertaining to the organization.

Abstract: A system for managing adaptive security zones in complex business operations, comprising a rules engine adapted to receive events from a plurality of event sources and a security manager coupled to the rules engine via a data network, wherein upon receiving an event, the rules engine determines what rules, if any, are triggered by the event and, upon triggering a rule, the rules engine determines if the rule pertains to security and, if so, sends a notification message to the security manager informing it of the triggered event, and wherein the security manager, on receiving a notification message from the rules engine, automatically establishes a new security zone based at least in part on the contents of the notification message, is disclosed.

Abstract: An audio device is provided that is arranged for communication of data and signalling with a controller, signalling from the device to the controller being made in discrete time slots, the device comprising: a plurality of nodes, each assigned a priority value and each having one or more unsolicited response sources capable of generating an unsolicited response for transmission to the controller, wherein unsolicited responses generated from a particular node are assigned the priority value of that node; and unsolicited response management means operable to hold unsolicited responses generated by the plurality of nodes that are awaiting transmission to the controller, wherein when two or more unsolicited responses are awaiting transmission to the controller in the unsolicited response management means, the device is arranged to transmit the unsolicited response with the highest assigned priority value first, in the next free time slot.
