Abstract

Detection of suspicious user behavior is essential in current scenario. It is required in various fields such as social networks, statistics, and knowledge discovery, finance etc. Web surfing through internet is growing rapidly than last few years. Total numbers of searching sites are more than billion and the same way the number of users increases in huge amount. The traditional cyber security system sometime fails as definition of anomalous has changed. The attacker uses new approach and innovative techniques to create vulnerability. So, there is a need for hybrid feature selection approach which can deal with this kind of threat. In this paper, an isolation forest approach has been proposed which utilizes a hybrid feature selection technique. The proposed feature selection approach uses one hot encoding with binning features and feature crosses with synthetic features. The final result shows the maximum accuracy. Proposed hybrid feature selection approach is tested on real time company dataset and it has been observed that this technique helps to identify suspicious activity in the social networks with greater accuracy. Here, the suspicious activities include; no of login failed, user location, excess time, no of file request, no of login.
