In this paper, we propose a novel Covert Timing Channel (CTC) detection method that leverages computationally low-cost statistical measures to precisely detect covert communication, using only minimum network traffic knowledge. The proposed detection approach utilizes three different non-parametric statistical tests to classify overt and covert inter-packet delays.
