Abstract
A plurality of access models comprise patterns of accesses to resources protected by an Access Control System (ACS). The access models are used to classify the accesses to the resources as either normal or anomalous. The system stores attributes for the individuals for whom the access models are available, receives attributes of an individual not associated with an access model, and compares the attributes of the individual not associated with an access model to the attributes of the individuals for whom access models are available. The system further selects an access model for the individual not associated with an access model based on the comparison, and uses the selected access model for the individual not associated with an access model to classify access to the one or more resources protected by the ACS by the individual not associated with an access model as either normal or anomalous.
