Abstract
Methods and systems are provided for evaluating atypical user data access activities within the scope of an automatically generated file security policy in organizations with multiple diverse access control models and multiple diverse file server protocols. The system monitors access to storage elements within the network. The recorded data traffic is analyzed to assess simultaneous data access groupings and user groupings, which reflect the actual organizational structure. The learned structure is then transformed into a dynamic file security policy, which is constantly adapted to organizational changes over time. The system provides a decision assistance interface for tracking abnormal user behavior.
