Security Information and Event Monitoring (SIEM)

Per Gartner, Security Information and Even Monitoring (SIEM) technology provides two major functions for security events from networks, systems and applications: Security Information Management (SIM) and Security Event Management (SEM).

SIM technologies focus more on the log management and compliance reporting aspects while SEM technologies focus more on the real-time monitoring and incident management aspects. Most vendors have solutions that meet both the SIM and SEM requirements but differ in their capability to achieve both.
