Forensic analysis

Abstract:

The present invention relates to a forensic analysis method performed on a Distributed Computing System (DCS) (10) comprising a server (18) and at least one client machine (14). The method comprises collecting data in a client machine (14) of the DCS (10) to form a first data set, the collected data being a function call to a resource comprised in the DCS. The method further comprises applying a data reduction model to the first data set to form a second data set and processing the second data set in the server (18) of the DCS (10) to provide for detection of suspect behaviour at the client machine (14). The data reduction model is configured to extract a subset of data from the first data set to form the second data set, the subset of data comprising: user account identifier; and process and object identifier.
