Survey of Dos Attacks, Detections & Prevention Frameworks for SIP Proxy Server
We researched the list of Voice over IP security papers, from a collection of 15 publications on Denial of Service attacks and also we categorized these papers based on their prevention mechanisms. Our objective is to identify the scope of VOIP researches in the area of DoS and to identify opportunities and numerous threats and vulnerabilities present in VoIP systems. We also discussed and analysed the scope of the results provided on those papers and also presented our comparisons among these publications. It seems that the findings in our analysis with respect to Denial of Service reported and prevented in a variety of ways for the VoIP products. Since, we identify specific problem area denial of service, which requiring attention from the research community. Our analysis reveals that the papers of the surveyed works took a lateral view of VoIP systems and that avoids few problems addressed in this area. At last, we laid roadmap for further work on understanding the mechanisms to detect and prevent Denial of Service attacks, which forms the by-product of a highly complex system-of-systems and an indication of the issues in future large-scale systems.
