RBA uses the existing Splunk Enterprise Security correlation search framework to collect all risk events into a single risk index. Events collected in the risk index create a single risk notable when they meet a specific criterion, which warrants an investigation. For example, suppose a single system creates five risk events from several risk rules. Each of these risk events have a low risk score. However, when taken together these risk event surpass the risk score threshold, pertain to specific MITRE ATT&CK techniques, and are associated with unique data sources over multiple time frames. RBA can pick up on this threat even when the system generates only a single risk notable because it performs correlated alerting that tells a high-fidelity security story, which analysts can investigate. Similarly, RBA effectively helps to detect complex behavior over a "p
