With the marvelous development of information technology & network security the Intrusion Detection (ID) has rapidly become a crucial component of any network defense strategy. Data stream classification is the superlative method for revealing of Intrusion Detection (ID). Improved One Versus All (OVA) is one of the multiclass classification techniques On the basis of this the authors propose the system on Network Intrusion Detection (NID) for security in network as well as computer. In this paper, improved one versus all decision tree algorithms identifies the behavioral attacks actions and newly arising attacks of intrusions.
