In order to avoid illegitimate use of any intruder, intrusion detection over the network is one of the critical issues. An intruder may enter any network or system or server by intruding malicious packets into the system in order to steal, sniff, manipulate or corrupt any useful and secret information, this process is referred to as intrusion whereas when packets are transmitted by intruder over the network for any purpose of intrusion is referred to as attack. With the expanding networking technology, millions of servers communicate with each other and this expansion is always in progress every day. Due to this fact, more and more intruders get attention; and so to overcome this need of smart intrusion detection model is a primary requirement.
By analyzing the feature selection methods the identification of essential features of NSL-KDD data set is done, then by using selected features and machine learning approach and analyzing the basic features of networks over the data set a hybrid algorithm is made. Finally a model is produced over the algorithm containing the rules for the network features.
A hybrid misuse intrusion detection model is made to find attacks on system to improve the intrusion detection. Based on prior features, intrusions on the system can be detected without any previous learning. This model contains the advantage of feature selection and machine learning techniques with misuse detection.
