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, such as servers, firewalls, and applications, to identify potential security threats. By centralizing this information, SIEM enables security teams to detect unusual activities and respond quickly to incidents. SIEM solutions often include features like data aggregation, correlation, and alerting. They help organizations comply with regulations and improve their overall security posture. By providing insights into security events, SIEM plays a crucial role in protecting sensitive information and maintaining a secure environment.
