Abstract: With the evolution of internet, network security has emerged as one of the key areas of research. Network security is to safeguard the privacy, availability and integrity of the system. Identification of intrusion is core component to attain overall network security success. Therefore, intrusion detection (ID) is broadly explored by researchers and idea of identification of intrusion has developed into a system, known as intrusion detection system (IDS). IDS focuses on investigation of attacks and offers desirable support for defence management along with information about the intrusion. Several intrusion detection approaches are already proposed to mitigate the impact of intrusion. In this paper, these techniques are discussed to highlight the state-of-the-art and a multilevel hybrid approach based on SVM-Naïve is proposed to predict malicious traffic from the network. Here, KNN along with k-fold cross validation is used to create new high-quality training dataset that outstandingly improved performance of classifiers. Performance of proposed model is evaluated by using standard KDD 1999 Cup dataset. Comparison of proposed model is carried out with existing techniques and it is analysed that its performance is better regarding exactness (99.73%), recognition rate of attack classes (99.81%) and FPR (0.21%).
