Security Information and Event Management. A platform that collects and correlates log data from firewalls, endpoints, servers, and applications across an organization. SIEMs apply detection rules and analytics to generate alerts, giving security analysts a single pane of glass for monitoring threats in real time.
Why SIEM Matters for Your Cybersecurity Career
SIEM is the central nervous system of every cybersecurity security operations center. SOC analysts spend most of their shifts investigating SIEM alerts in platforms like Splunk, Microsoft Sentinel, or IBM QRadar. Writing detection rules and tuning alert thresholds are core skills for any detection-focused role.
