The Internet is becoming part and parcel of everyone in everyday life. Almost all people are depending heavily on the Internet for all types of online activities. Hence, many Information Technology (IT) companies and organizations do business with people or enable businesses for people by running and/or supporting online web services continuously and try to attain or guarantee continuous service availability. From the old and recent bitter experiences of web servers with Distributed DoS (DDoS) attacks, one can realize that they become a serious threat to web site’s availability. Along similar lines, flash crowds also prove to be damaging to web servers by losing business, if not properly discriminated from DDoS attacks and handled well. In this context, the task of differentiating the DDoS attacks from the flash crowds gets more significance and hence, we carried out an extensive survey over this. We analysed numerous existing approaches and compared important features used for discrimination.
