Covert channels are among the serious and most complicated security flaws that attempt to broke the access control policies, since they allow an unplanned communication medium within an information system. The important impact of this vulnerability gives it a wide interest by the researchers. In this paper, we propose a new approach based on an enhanced version of the shared resources matrix method, where the principle of mutation analysis is integrated to allow an efficient and fast detection of covert channels. We have conducted an evaluation within a real system and the obtained results show very promising performances.
