DoS: An exploit whose purpose is to deny somebody the use of the service: namely to crash or hang a program or the entire system. Examples of DoS attacks include flooding the victim with more traffic than can be handled; flooding a service (like IRC) with more events than it can handle bomb; crashing a TCP/IP stack by sending corrupt packets; crashing a service by interacting with it in an unexpected way; or hanging a system by causing it to go into an infinite loop. For example, the Ping of Death exploit crashed machines by sending illegally fragmented packets at a victim. A common word for DoS is ""nuke"", which was first popularized by the WinNuke program.
DDoS: A Distributed Denial of Service (DDoS) attack is one that pits many machines against a single victim. An example is the attacks of February 2000 against some of the biggest websites. Even though these websites have a theoretical bandwidth of a gigabit/second, distributing many agents throughout the Internet flooding them with traffic can bring them down. The Internet is defenseless against these attacks. The best defense is for users everywhere to run PestPatrol, and remove DDoS clients when they are found, so that their machines are not used as attack tools. Another approach is for ISPs to do ""egress filtering"": prevent packets from going outbound that do not originate from IP addresses assigned to the ISP. This cuts down on the problem of spoofed IP addresses.
