Complete guide to Security Information and Event Management
Security Information and Event Management (SIEM) is a solution that provides monitoring, detection, and alerting of security events or incidents within an IT environment. It provides a comprehensive and centralized view of the security posture of an IT infrastructure. It gives cybersecurity professionals insights into the activities within their IT environment.
How does SIEM work?
SIEM software collects and aggregates log data generated throughout the organization’s entire IT infrastructure. From cloud systems and applications, to network and security devices, such as firewalls and antivirus. The software then identifies, categorizes and analyzes incidents and events. SIEM analytics delivers real-time alerts, dashboards, and reports to several critical business and management units. Modern SIEMs also apply unsupervised machine learning to enable anomaly detection (User and Entity Behavior Analytics) to the collected log data.
