Identification of Application Protocols
Wrona, Jan ; Bartoš, Václav (referee) ; Kořenek, Jan (advisor)
This thesis is focused on identification of application protocols with emphasizing the speed of their recognition and following possibility of hardware implementation. Nowadays tools are not suitable for fast identification of application protocols in current network monitoring devices, because the decision is not provided for the first packets of network flow. Therefore this thesis propose new model for fast and reliable identification of application protocols. The model was implemented and tested on HTTP, SIP, SMTP and DNS protocols and results were compared to regular expressions and nDPI and libprotoident libraries. For all these protocols, the proposed model has comparable accuracy to other methods, but also provides fast result based on the first packets of the flow.
