What is a SIEM system used for?

A Security Information and Event Management (SIEM) system is specifically designed to collect and analyze security data from across an organization’s IT environment. This includes gathering logs and security events from various sources such as servers, network devices, domain controllers, and other security appliances. By correlating this data, a SIEM can help identify patterns, detect threats, and provide insights into both ongoing and potential security incidents.

This systematic collection and analysis enable security professionals to respond more effectively to incidents, comply with regulations, and enhance the overall security posture of the organization. The real-time monitoring and historical data analysis capabilities of SIEM systems support incident management, forensic investigations, and compliance reporting, making them essential tools in modern cybersecurity practices.
