A Technique of Classification of Data Using NIDS And Response System

ABSTRACT With the growth of network-based services and sensitive information on networks, network security is becoming more important. Intrusion detection techniques is defenses against computer attacks behind firewalls, secure network architecture design and personal screening. The number of network attacks has risen leading to the essentials of network intrusion detection systems to secure the network. Intrusion Detection Systems (IDSs) plays an important role in network security. IDSs can monitor events at the endpoints or on the network, with huge traffic volumes and heterogeneous accesses, several pattern identification techniques have been brought into the research community. The security of a computer system is compromised when an intrusion is took place. An intrusion can be defined as any set of actions that attempt to compromise of confidentiality, availability or integrity of a resource. Data mining or KDD is a process of the process of identifying valid, useful and understandable patterns in data.
