About

IBM QRadar is a Security Information and Event Management (SIEM) solution that provides real-time visibility into enterprise-wide activities to help detect, investigate, and respond to threats. It collects and analyzes security data from various sources, including logs, flows, vulnerabilities, and user behavior—enabling centralized threat detection and incident response.

In my homelab environment, QRadar is one of my most-used tools. By aggregating data from multiple simulated endpoints and network devices, QRadar allows me to develop and test use cases for log correlation, rule creation, offense generation, and automated alerting. This hands-on experience has deepened my understanding of threat detection techniques, event parsing, and the overall security operations workflow. Adding QRadar to my lab environment was very important in that it has helped me build real-world skills in managing a SIEM platform, enabling me to proactively identify and respond to cybersecurity threats in a controlled setting.
