Intrusion detection and prevention system: Challenges & opportunities

The idea of making everything available readily and universally has led to a revolution in the field of networks. In spite of the tremendous growth of technologies in the field of networks and information technology, we still lack in preventing our resources from theft/attacks. This may not concern small organizations but it is a serious issue as far as industry/companies or national security is concerned. Organizations are facing an increasing number of threats every day in the form of viruses, intrusions, etc. Since many different mechanisms were opted by organizations in the form of intrusion detection and prevention systems to protect themselves from these kinds of attacks, there are many security breaches which go undetected. In order to understand the security risks and IDPS(intrusion detection and prevention system), we will first survey about the common security breaches and then after discuss what are different opportunities and challenges in this particular field. In this paper we have made a survey on the overall progress of intrusion detection systems. We survey the existing types, techniques and architectures of Intrusion Detection Systems in the literature. Finally we outline the present research challenges and issue.
