On the Limitation of Covert Channels Bandwidth in IP Networks
Anna Belozubova, Konstantin Kogos · DOAJ (DOAJ: Directory of Open Access Journals) · 2015
Features of packet switching networks and the blanket distribution of high-speed IP networks result in widespread research of covert channels. Adversary’s possibilities used to build covert channels in IP networks were analyzed. Traffic encryption does not protect against a wide range of covert channels, and the presence of resistant to the detection encoding schemes makes necessary to introduce preventive countermeasures against to the potential covert channels. The compliance between the mechanisms of covert channels construction in IP networks and the methods of eliminating and bandwidth limitation was matched.
