Visualization Method for Time and Space Logic Correlation of Security Audit Event

This paper describes security audit event in the form of Unified Modeling Language(UML)with the idea of object oriented theory,and proposes security audit event visualization model based on the theory of colored Petri-net.Based on this model,with the file operation audit events,it gives a visualization method for time and space logic correlation of security audit event.The method provides convenience and assistant of browsing and analyzing audit data for security auditor.
