Considering several scenarios in network attacks and dissimilar attacks

Intrusion detection systems is playing major role in network attacks detection. The algorithms that is placed in them, are improving continuously. During two years, the major of efforts is focused to distributing these systems. So considering the traffic overhead in networks is important. We consider several scenarios for attacks that are happened in networks. Also, we consider several scenarios for dissimilar attacks. The result that is obtained in this paper shows if even the rate of dissimilar attacks is high, the rate of dissimilar attacks is reducing by the time. This paper can help to researchers to increase the collaborative platform between IDSs.
