What does QRadar use to correlate events across different log sources?

QRadar utilizes correlation rules to analyze and combine events from various log sources, identifying patterns and anomalies that could signify security incidents. These rules are predefined or can be customized to fit specific organizational needs, allowing QRadar to automatically correlate related events, allowing it to detect complex threats that might not be evident when considering each log source in isolation.

Correlation rules are essential for real-time threat detection because they enable the platform to apply logical conditions to incoming data, facilitating actionable insights. This capability is at the core of QRadar’s effectiveness as a SIEM solution, as it automates the analysis process and enhances incident response by prioritizing alerts based on the context provided by correlated events.
