SIEM

Security Information and Event Management is software that collects, aggregates, and correlates log and event data from across the IT infrastructure to provide real-time analysis of security alerts.

SIEM stands for Security Information and Event Management. It is a type of software solution that provides real-time analysis of security alerts generated by network hardware and applications. SIEM systems collect log and event data from a variety of sources across the IT infrastructure, then aggregate and normalize this data for analysis.

SIEM systems help organizations detect security threats and manage compliance reporting by providing a centralized view of the organization's security posture. They aggregate, analyze and correlate data from diverse IT infrastructure components, providing security teams a comprehensive view of potential security threats, to facilitate more efficient analysis and remediation of security incidents.

For small and medium businesses, a SIEM is a valuable tool for maintaining security. Want to learn more? Check out our choosing guide:
