Security challenges in intrusion detection

Organizations and governments consider security as a must-have due to the increasing rate of attacks which is threatening both security and privacy. In this paper, we present a survey of IDPS which led us to perform a classification of methods depending on the techniques used in intrusions detection and prevention systems. We also discuss the advantages and drawbacks of these methods. Afterwards, we discuss the various problems complicating the proper functionality and efficiency of the current IDPS and also analyze its challenges in cloud computing, smart-phones and smart cities.
