Abstract
Known legitimate applications are analyzed to establish a list of trusted user-agent strings used by the applications to download content from a network. Traffic interception modules connected to the network examine traffic exchanged between clients and servers on the network, recognize traffic associated with downloads of content from the network, and create content download descriptions describing the downloads. The content download descriptions are analyzed to identify content downloads using the trusted user-agent strings. Identifiers of the content downloaded using the trusted user-agent strings are added to a white list of legitimate content. Access to the white list is provided to clients and the clients use the white list to identify legitimate content.
