SIEM tools enable real-time monitoring, threat detection, and incident response by combining log aggregation, event correlation, and reporting capabilities. They gather information from various sources, including firewalls, intrusion detection systems, antivirus software, and other network devices, to identify patterns that may indicate a security breach or policy violation. Using this data, SIEM solutions can produce alerts and reports for the security operations team, enabling them to quickly respond to threats and maintain compliance with industry regulations. By providing increased visibility into an organization's security posture, SIEM solutions can help facilitate more informed decision-making and enhance overall security operations.
