Real-time log file analysis using the Simple Event Correlator (SEC)
John P. Rouillard · 2004
Log analysis is an important way to keep track of computers and networks. The use of automated anal-ysis always results in false reports, however these can be minimized by proper specification of recognition criteria. Current analysis approaches fail to provide sufficient support for the recognizing the temporal component of log analysis. Temporal recognition of event sequences fall into distinct patterns that can be used to reduce false alerts and improve the efficiency of response to problems. This paper discusses these patterns while describing the rationale behind and implementation of a ruleset created at the CS depart-ment of the University of Massachusetts at Boston for SEC- the Simple Event Correlation program. 1
