Abstract

An edge server receives a plurality of requests from a client network application for actions to be performed on a resource that is hosted at an origin server. The edge server determines request attributes of the requests and associates the request attributes with a session identifying the client network application. The edge server generates a confidence value for the client network application based at least on the determined request attributes of the plurality of requests and computed session metrics of the session. When the confidence value indicates that the client network application is malicious, the edge server performs one or more mitigation actions.
