Abstract

A network security device (NSD) is connected between a network and an endpoint device configured to host a client application. The client application communicates with the network through the network security device using a request-response protocol. The NSD receives from the client application a request destined for the network and that seeks a response from the network. The request has a context header including context information about the client application. The NSD determines whether the client application or a file accessed thereby has a suspicious nature based on the context information. If it is determined that the client application or the file accessed thereby has a suspicious nature, the NSD blocks the request from the network, and sends to the client application a response indicating the block.
