Abstract: “For many years, researchers have used the discovery of intrusion technology to supply the security of networks and computer systems. Increasing Cyber threats has caused the need to have a flexible approach that can offer the efficiency of this type of attack and to deal with more complex and unknown attacks. On this basis, the systems of intrusion discovery based on data mining have been presented that derives the unknown patterns and Cyber attacks from the data network. What is presented in this paper is an improvement on Apriori algorithm to realize the intrusion pattern in less time in the network and take proper reaction against it.”
