SIEM (Security Information and Event Management)
Centralized platform that collects, analyzes, and correlates security data from across an organization's infrastructure.
Overview
SIEM systems are the nerve center of modern security operations. They aggregate logs and events from firewalls, servers, endpoints, applications, and security tools, providing a unified view of the security landscape. Advanced SIEMs use correlation rules and machine learning to identify patterns indicating security incidents. They enable real-time monitoring, threat detection, compliance reporting, and forensic investigation. However, traditional SIEMs can be complex to manage and generate alert fatigue. Next-generation systems incorporate AI and automation to reduce false positives and accelerate response. Integration with threat intelligence feeds enhances detection capabilities.
