Security information and event management (SIEM) technology in essence has two parts, the Security Information Management where information is collected and the Security Event Management, where events are analyzed and categorized for severity.
SIEM solutions need data from multiple sources as part of data aggregation, normalization, and collection. The data collected are a series of recorded events, providing a history of activity. Once the SIEM system has the data, it can be used for detection of events and to analyze historical events. If you have incident reporting requirements from external parties or from regulatory requirements, SIEM is a must have.
In organizations with a Security Operations Center (SOC), SIEM technology is the core system to effectively identify and analyze security events. Most of the security analysis in a SOC, is automated using systems capable of filtering and prioritizing the most serious security events. This allows the SOC analysts to be able to quickly deal with security incidents very quickly, instead of having to manually scan through large amounts of security event.
