What does SIEM stand for, and what is its main purpose?

SIEM stands for Security Information and Event Management. Its main purpose is to aggregate security data from various sources within an organization's IT infrastructure, such as servers, network devices, domain controllers, and more. By collecting and analyzing this data, SIEM solutions provide security professionals with real-time insights into security events and incidents, enabling them to detect, respond to, and manage potential threats effectively.

The aggregation of security data allows organizations to correlate events across different systems, which can help identify patterns and anomalies that may indicate security breaches, compliance violations, or other security-related issues. This functionality is crucial for maintaining an organization's security posture, as it supports incident detection, investigation, and reporting, thereby enhancing overall security awareness and response capabilities.
