But log file is not to be over emphasized as a source of information in systems and network management. Whereas conduct efficient investigation and gathering of use full information need to correlate different log file. Task of analyzing event log files with the ever-increasing size and complexity of today’s event logs has become cumbrous to carry out manually. Nowadays latest spotlighted is automatic analysis of these logs files. . This paper present an bird eye on two basic concepts one is temporal data mining and another is fuzzy association rules. Using log files it is possible to classify the attacker from the normal user. Keywords- Event Logging, Fuzzy Logic, Temporal Correlation I INTRODUCTION Event logging and event logs play an [1] important role in modern IT systems. Today, many applications, operating systems, network devices, and other system components are able to log their events to a local or remote log server. For this reason, event logs are an excellent source for determining the health status of the system, and a number of tools have been developed over the past 10-15 years for monitoring event logs in real-time. However, majority of these tools can accomplish simple tasks only, e.g., raise an alarm immediately after a fault message has been appended to a log file. On the other hand, quite many essential event processing tasks involve event correlation a conceptual interpretation procedure where new meaning is assigned to a set of events that happen within a predefined time interval. Event correlation is one of the most prominent real-
