SIEM stands for Security Information & Event Management that provides a real time analysis of security alerts generated by computer and network security devices such as Firewall, Router, IDS/IPS, Server, Switch etc. SIEM is a combination of two tools Security Information Management (SIM) & Security Event Management (SEM). SIM is the collection, monitoring, and analysis of security-related data from computer generated logs. While SEM is the practice of network event management including real-time threat analysis, visualization, and incident response. There are more than 50+ SIEM tools available in the market.
