CLASSIFICATION OF UNKNOWN NETWORK TRAFFIC

Abstract:

A network device may receive network traffic for an application. The network device may determine a first classification for the network traffic according to a first classification technique. The first classification may identify the network traffic as relating to a particular application or an unknown application. The network device may determine a second classification for the network traffic according to a second classification technique. The second classification may identify the network traffic as relating to an unknown application of a particular type and identity. The network device may process, based on whether the first classification identifies the network traffic as relating to the particular application or the unknown application, the network traffic according to a first security policy associated with the particular application or a second security policy associated with the unknown application of the particular type and identity.
