Abstract: An apparatus, method and computer program product is provided in accordance with embodiments of the disclosure, for identifying a message of interest exchanged between nodes in a network.

Abstract: An apparatus, method and computer program product are provided, the apparatus for identifying a set of messages of interest in a network, the apparatus comprising circuitry configured to: receive information of a plurality of sets of messages which have been exchanged by nodes in a network; select a portion of the plurality of sets of messages which have been received using a property of a source message of each set of messages of the plurality of sets of messages; generate individual first values for the nodes of each set of messages of the selected portion of the plurality of sets of messages using a property of the nodes associated with each set of messages; and identify at least one set of messages of the selected portion of the plurality of sets of messages as a set of messages of interest using the individual first values which have been generated for the selected portion of the sets of messages.

Abstract: A method, apparatus and computer program product for identifying accounts of interest in a network are provided, the method comprising controlling circuitry to: receive information indicative of a plurality of target accounts, the plurality of target accounts including at least a portion of the accounts in the network; monitor for each target account of the plurality of target accounts, at a number of instances of time, connections between that target account and other accounts in the network; using a result of the monitoring, select target accounts associated with an increase of connections to accounts in the network with which the target account has no previous connection, above a first threshold level, as a first set of accounts; using a result of the monitoring, select target accounts associated with a decrease in connections to accounts in the network with which the target account has a previous connection, above a second threshold level, as a second set of accounts; and identify at least one target acco

Abstract: The present disclosure concerns a computer-implemented method for forensically analysing and determining a network associated with a network security threat. The method comprises: obtaining details of a flagged network event comprising data associated with a network security threat, the network event being between a first dataset and a destination dataset; tracing the data associated with the network security threat from the first dataset to a further dataset, the tracing involving obtaining details of at least one past network event between the first dataset and the further dataset; comparing details of the further dataset to predefined criteria to identify whether the further dataset is an intermediate dataset or a source dataset from which the data originated and adding the details of the further dataset to a forensic report; outputting the forensic report.
