Protection from binary and multi-symbol packet length covert channels
Anna Vasilievna Epishkina, Konstantin Kogos · 2015
In this paper, we describe binary and multi-symbol packet length covert channels. Then we design a technique to estimate and limit their capacity. The method to choose parameters of counteraction tools is given, it takes into account an allowable value of covert channel capacity and error level. The novelty of the investigation undertaken is that the covert channel capacity is limited preliminary, whereas state of the art methods focus on detecting active IP covert channels.
