Security Information and Event Management (SIEM) is a technology that helps organizations monitor and analyze security data from various sources in real-time. It collects logs and events from different systems, applications, and devices, allowing security teams to detect potential threats and respond quickly. SIEM systems provide a centralized view of security incidents, making it easier to identify patterns and anomalies. By correlating data from multiple sources, SIEM enhances an organization's ability to comply with regulations and improve overall security posture, ultimately protecting sensitive information and reducing risks.
