Abstract: A first processing component samples and lossily accumulates statistical activity data by generating at least one data bucket by segmenting a memory window in a memory and providing a map of the segmented memory window; sampling to detect activity in the data bucket and surjectively populating the map with statistical activity data; and responsive to a trigger, passing at least part of a population of the map to a second processing component. The second processing component receives and stores the at least part of the population of the surjective map, compares it with at least one previously stored map population; and on detecting anomalous patterning, performs an “anomaly detected” action.

Abstract: A network management module receives requests for operation data from a device and determines a response to be sent to the device indicative of an user's responses to prior operation data requests. The user's responses to operation data requests are shared by the network management module with one or more devices, reducing the number of responses required directly from the user. In addition, the user responses to operation data requests from a first device may be used to derive the user's response to other operation data requests from the same device or from one or more different devices, of the same or different type.

Abstract: A network management agent is provided to enable a secure connection to a network to be established. The network management agent confirms the identity of a device upon receipt of a device identifier from the device, via a first communication channel, and responds with a security token, via the first communication channel, which the device uses to confirm the identity of the network management agent. The network management agent is able to trust the device and the device is able to trust the network management agent, such that the device may be granted access to a network which it trusts. The network management agent may be provided, via a second communication channel, with a device identifier and a device security token for the device from which the security token to be transmitted over the first channel is derived.
