Survey on Covert Storage Channel in Computer Network Protocols Detection and Mitigation Techniques
A MUAWIA, Ahmed Yahia · 2016
Due to the rapid growth in number of different protocols over the internet, internet protocols have become an ideal vehicle for covert communications.They represent a high bandwidth for such communications.Moreover, new highspeed network technology has significantly amplified the network's covert channel capacity.Certainly, a covert channel bandwidth of only one bit size can easily allow transmission of a system bin code which can lead to tremendous risk.This paper presents a brief overview of network protocols-based covert channels, and surveys some recent and relevant work on covert channels detection and elimination techniques along with their achievements and limitations.In sum, the covert channel countermeasures-detection, elimination, mitigation, and capacity reduction-are still real challenges and lag behind an acceptable level of network security.Therefore, the research door is wide open for more contributions in this field.
