How do security information and event management (SIEM) systems work?

Security Information and Event Management (SIEM) systems provide centralized analysis of security data by collecting log data generated throughout a company’s technology infrastructure, including network devices, servers, applications, and more. These systems aggregate and normalize the data, making it easier to analyze and detect security incidents. SIEM systems use correlation rules and algorithms to identify patterns indicative of security threats, allowing security teams to respond more effectively to potential risks. Additionally, SIEM systems provide real-time monitoring, alerting, and reporting functionalities to help organizations maintain a proactive security posture.
