Describe Denial or Degradation of Service.

Answers

A denial-of-service (DoS) or distributed denial-of-service (DDoS) attack is an attempt to make a machine or network resource unavailable to its intended users. A DoS attack generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.There are many ways to disrupt service, including such physical means as arson or explosions; shutting off power, air conditioning, or water (needed by air conditioning systems); or performing various kinds of electromagnetic disturbances.
Turning off power or sending messages to system software telling it to stop processing are examples of the first type of attack--a classic denial of service.
The other type of attack, known as flooding (or sometimes wedging or spamming) is the type employed by the Internet worm. As the worm spread across systems and networks, it keeps creating new processes that clogged the affected systems that other work cannot get done.
