Security information and event management (siem)

Definition

Security Information and Event Management (SIEM) is a comprehensive solution that combines security information management (SIM) and security event management (SEM) to provide real-time analysis, monitoring, and reporting of security events within an organization. SIEM systems collect and analyze data from various sources, including servers, network devices, and applications, to detect anomalies and potential security threats. By offering a centralized view of security incidents, SIEM is crucial for maintaining operating system security, facilitating secure software development, and enhancing incident response capabilities.
