Security Information and Event Management (SIEM) is a cybersecurity solution that collects, analyzes, and correlates security data from various sources across an organization’s IT infrastructure. It provides real-time threat detection, log management, incident response, and compliance reporting by aggregating data from firewalls, intrusion detection systems (IDS), endpoint security tools, and network devices. SIEM solutions use advanced analytics, machine learning, and threat intelligence to identify security incidents, detect anomalies, and respond to cyber threats. Popular SIEM platforms include Splunk, IBM QRadar, Microsoft Sentinel, and ArcSight. By providing centralized security monitoring and automated alerts, SIEM helps organizations improve threat visibility, reduce response times, and maintain compliance with security regulations like PCI DSS, HIPAA, and NIST.
