User and Entity Behavior Logs
For supported software information, click here.
User and entity behavior analytics (UEBA) uses machine learning and advanced analytics to detect abnormal user activities in a network. Versa UEBA is a cloud service that provides a layer of security that enables your organization to monitor, detect, and respond to suspicious behaviors across your network infrastructure. Unlike security measures that focus on known attack signatures, UEBA continuously monitors and learns from user interactions, which helps security teams to identify anomalies in real-time and respond proactively to threats.
UEBA logs are exported to Analytics nodes by Versa messaging service (VMS) nodes. User entity score logs are exported to Analytics nodes by SASE gateways.
UEBA Logs
VMS exports UEBA logs when a UEBA application running in the cloud detects an anomalous event.
