Abstract
Systems and methods of handling sessions between client devices and one or more server based on session classifications are provided. A device identifies a time series of security metrics corresponding to requests received during a session established by a client device to access a resource provided by one or more servers. The device generates security features from the time series of security metrics based on one or more time windows. The device classifies the session as one of anomalous or genuine using the security features generated from the time series of security metrics based on the one or more time windows. The device handles subsequent requests received during the session based on the classification of the session as the one of anomalous or genuine.
