11 Best SIEM Tools For Real-Time Incident Response And Security

SIEM stands for Security Information and Event Management system which provides real-time analysis of security alerts using applications. It includes systems for Security log management, security event correlation, security information management and log management. SIEM tools work in the area of Security Event Management as well as Security Information Management.

Security event management can help perform threat evaluation and monitoring, incident response and event correlation. It performs the function of collecting, analyzing and reporting of log data.

How does SIEM software work?

A SIEM software works by gathering the security log data which is generated by an array of sources such as host systems and security devices such as antivirus and firewalls. The second step is to process this data into a standard format. With a standard format, the next step is to perform an analysis for identifying and categorizing incidents. Hence, the alerts are generated in case a security issue has been identified. Besides this, SIEM software provides reports which are related to security events.

Let’s take a look at the best SIEM tools to help to tackle security incidents.
