Recent years have seen numerous Denial Of Service (DOS) and Distributed Denial Of Service (DDOS) attacks against corporate web servers. One of these attacks closed down the Amazon web server for almost an entire day.DOS attacks on corporate web servers can cost companies a great deal of money as well as loss of corporate image in the eyes of its customers. In this paper, the authors present an algorithmic approach to detect DOS and DDOS attacks at the web server. The primary contribution of this algorithm is to act as first line alert system, notifying IT personnel that an attack is likely underway.
