CURRENT BEHAVIOR EVALUATION WITH MULTIPLE PROCESS MODELS

摘要

Current behavior can be evaluated to efficiently identify behavioral anomalies with process models of different scopes and/or different degrees of precision. For meaningful behavioral evaluation of an actor (i.e., a user or a device), these multiple process models are constructed with different sets of event logs of a system. A model of a scope of an individual actor and a model of a scope of a group of actors are constructed and used for evaluation. These models of different scope expand “normal” behavior of an actor to include behavior of the group of actors. Although these process models of different scopes likely have different precision, additional models of different precision and/or different scopes can be constructed and used for behavioral evaluation. These different process models allow for behavioral variation within relevant groups of actors.
