Since the bandwidth in a network is finite, the number of connections a web server can maintain is limited. Each connection to a server needs some minimum amount of network capacity in order to function properly. When a server has used up its bandwidth (the ability of its processors to respond to requests), any additional attempted connections are dropped. Any attack that is designed to cause a machine or a piece of software to be unavailable and unable to perform its basic functionality is known as a denial of service (DoS) attack. A majority of DoS attacks refer to deliberate attempts to exceed the maximum available bandwidth of a server usually through exploiting program flaws or resource exhaustion. The underlying concept is that since different parts of the system might have different resource limits, the attack only needs to exhaust the part of the system with the least resources (i.e. the bottleneck). Since attackers in a DoS attack are not concerned with receiving responses fro
