What is a SIEM system used for?

• A. A tool to manage network switches.
• B. A backup storage appliance.
• C. A technology used in enterprise organizations to provide real time reporting and long-term analysis of security events.
• D. An email security gateway.

Answer: (C)

SIEM brings together security information and event data from many sources into a centralized system. It collects logs and alerts from firewalls, endpoints, servers, applications, cloud services, and identity systems, then correlates events to spot patterns that could indicate a threat. It provides real-time reporting and alerts to security staff, and it stores data long-term for forensic analysis, compliance reporting, and trend analysis. This combination of live visibility and historical analysis is what makes a SIEM essential for detecting, investigating, and responding to security events over time.
