===Denial-of-service attacks===

The denial-of-service attack is unlike most others in that it does not require any infiltration of the target.  Anyone with enough computers (or a botnet) can perpetrate this attack.  While systems have evolved to resist "the ping of death," they can still be overloaded or disconnected by their Internet Service Provider (ISP).  In this attack, a target is usually flooded with "head" requests, which come at a rate greater than the server can respond.  Eventually, the server will either overload and crash, or as usually intended by the attacker, the ISP will deny service to the target because the flood of traffic is slowing down their network.  Servers and computer systems can be designed to resist these attacks, but the flood of requests alone can result in a service denial.
