UBA (User Behavior Analytics) is a threat detection technology that tracks, collects, and analyzes user behavior to discover traffic patterns and identify anomalous activity. UBA systems are not designed to react to their findings but to provide cybersecurity professionals with information they can act on.
UBA is also frequently referred to as UEBA (User and Entity Behavior Analytics) to emphasize that it does not only track user behavior but also the actions of network devices, applications, and processes.
