Security incident and event management (SIEM) technology helps organizations do what might otherwise be impossible for even a large and well-trained IT team working with outdated tools: identify the full scope of potential risks and how to mitigate them.
By aggregating threats, analyzing them and alerting network security monitors to their presence, SIEM solutions help businesses stay one step ahead of cyber threats. A robust SIEM can cover an organization's entire infrastructure, collecting data from servers, domain controllers, network devices and other sources.
How security incident and event management works
SIEM culls data from basic intrusion detection tools and firewalls as part of its intelligence-gathering process, but it goes farther than either does alone. It provides rich reporting capabilities that help businesses understand current trends and where IT systems might be vulnerable to attack.
Companies can use security incident and event monitoring solutions to identify abnormal behavior—such as a login attempt at an unusual time or an unauthorized download onto an endpoint—that might otherwise get ignored or missed. SIEM can cross-reference suspicious activity against established business rules and curated threat intelligence, and then alert the IT security team. Correlating anomalies between devices and endpoints can provide IT departments with forensics that can dramatically improve how they assess and address risk.
