What is SIEM Software in the UK?
SIEM software, or Security Information and Event Management software, is an integrated suite of applications used to monitor, analyze, detect, and respond to security threats. It collects data from multiple sources within a network such as network devices, operating systems, applications and databases. This data is correlated and analyzed in order to identify potential security threats. The SIEM then provides automated responses to these threats. This includes alerting the appropriate personnel on the threat as well as taking necessary action on compromised accounts or malicious activities. Furthermore, it can also provide reporting capabilities for compliance requirements such as audit logs.
