ISC2 CISSP Practice Question

A Security Information and Event Management (SIEM) system's primary function is to collect and analyze security event data from multiple sources across an organization's IT infrastructure. SIEM systems aggregate log data and security events from various network devices, systems, and applications, then correlate this information to identify patterns that might indicate security threats or incidents. This centralized approach to security monitoring enables security teams to detect, analyze, and respond to security incidents more effectively by providing a holistic view of the organization's security posture rather than isolated alerts from individual systems.
