For event management (EM), there are special event management systems that correlate and analyze the countless log files of security systems and their firewalls
.Deviations can be detected from this event data and important conclusions drawn
Eventmanagement systems can not only evaluate the correlated event data, but they can also automatically take appropriate measures to derive threats. For this purpose, event management systems link the log data of the various units in real time, weight the events, register their deviation and reduce the amount of data generated. The software used for this purpose is Event Log Management Software (ELMS).
