Defending computer networks from covert channels is a challenging task in TCP/IP networks. It is necessary for system engineers to know covert channels in order that they are going to be able to pre-emptively overcome sure security issues. In this paper we propose a new method to find the information hidden in TCP initial sequence numbers (ISNs) through this we can detect difficult covert channels. In our method we create reconstructed phase space by processing space using phase space reconstruction, thus a variety model for detecting covert channels in TCP ISNs. By using this model, a variety algorithm is developed to identify the existence of information hidden in ISNs. Results have demonstrated that our proposed detection method performs high detection accuracy and good reduced computational complexity. We can use this not only in offline but also in online detection.
