What Is SIEM?
Security, information, and event management (SIEM) is a technology that provides organizations with next-generation detection, response, and analytics. In essence, SIEM combines the capabilities of security information management (SIM) and security event management (SEM).
By doing this, SIEM is able to provide real-time analysis of the security alerts applications and network hardware generate. SIEM identifies events and indexes them for a sub-second search based on the rules set. During the search, it analyzes threats using globally gathered intelligence.
In order to get the best out of SIEM solutions, they must be accompanied by a Security Operation Center (SOC).
