Denial of Service (DoS) Attacks
A denial of service attack, or DOS attack, is an assault upon a network or web site that floods it with so many additional requests that regular services are either slow or completely interrupted. In some instances, a group or remotely controlled, compromised desktops are combined to jointly attack a target system, this is known as a distributed denial of service.
