With the rapid expansion of computer networks during the past decade. security has become a crucial issue for computer systems. Different soft-computing based methods have been proposed in recent years for the development of intrusion detection systems (IDSs). The purpose of this paper is to use ID3 algorithm for IDS and extend it to deal not only with discreet values. https://www.chiggate.com/used-ross-700mc-bone-in-commercial-meat-tenderizer-online/
