Intrusions Detection Systems (IDSs) are used to detect attacks. Intrusion detection systems gather network traffic information on computer system and then use this information to secure the network. Intrusion Detection systems are many types. Misuse - based and anomaly-based are the types of Intrusion detection systems. Misuse - based IDS only detect known attacks, anomaly based IDS detect the new attacks. Now days data mining methods have gained importance in addressing network security issues, including network intrusion detection. This paper proposes a new method to detect intrusions.
