What is Security Information and Event Management (SIEM)?

Security information and event management (SIEM) is a system that collects, correlates, analyzes, and maintains detailed event logs and data from multiple resources within an organization. Such SIEM solutions are used to provide real-time monitoring, threat detection, and incident response capabilities by leveraging these event logs and data from network devices, servers, applications, and other sources to identify security incidents, conduct forensic investigations, and appropriately support compliance reporting.
