Extending encrypted traffic analytics with traffic flow data

Abstract

Techniques for enriching encrypted traffic analytics are presented. In one embodiment, a method includes obtaining telemetry data for one or more domains within a network. The telemetry data includes both encrypted traffic analytics information and traffic flow information associated with the network traffic. For each domain of the one or more domains, the method also includes generating a model comprising a mapping from a plurality of traffic flow information features to at least one encrypted traffic analytics feature. The method includes generating a database comprising generated models for each of the domains and obtaining telemetry data for a target domain that includes traffic flow information, but does not include encrypted traffic analytics information. At least one encrypted traffic analytics feature of the target domain is determined based on a plurality of traffic flow information features of the target domain using the database.
