Abstract: In one embodiment, a method for classifying an encrypted flow includes receiving a plurality of packets associated with an encrypted flow traversing a network, collecting telemetry data from the flow without decrypting the flow, sending the telemetry data to a backend system for classification, using the telemetry data to classify the flow using a machine learning classifier, creating a classification response, and using the classification response to modify processing of the flow. In another embodiment, a method for classifying an encrypted flow includes receiving a plurality of packets associated with an encrypted flow traversing a network, collecting telemetry data from the first plurality of packets associated with the flow, sending the telemetry data to a backend system for classification, using the telemetry data to classify the flow using a machine learning classifier, and using the output of the classifier to modify processing of the flow.

CPC classification number: H04Q9/02 , H04L63/166 , H04L63/0428 , H04Q9/00 , H04L9/3066 , H04L63/0823 , H04Q2209/30
Abstract: In one embodiment, a method includes receiving a traffic flow including a plurality of packets encrypted using a cryptographic protocol, determining cryptographic protocol data of the traffic flow, and transmitting telemetry data of the traffic flow including the cryptographic protocol data. In another embodiment, a method includes receiving telemetry data of a traffic flow including a plurality of packets encrypted using a cryptographic protocol, the telemetry data including cryptographic protocol data of the traffic flow, classifying the traffic flow based on the cryptographic protocol data using a machine learning classifier; and taking a remedial action with respect to the traffic flow based on the classification of the traffic flow.
