Network Denial-of-Service Attack


Topic Last Modified: 2011-02-21

The denial-of-service attack occurs when the attacker prevents normal network use and function by valid users. By using a denial-of-service attack, the attacker can:

  • Send invalid data to applications and services running in the attacked network to disrupt their normal function.

  • Send a large amount of traffic, overloading the system until it stops responding or responds slowly to legitimate requests.

  • Hide the evidence of the attacks.

  • Prevent users from accessing network resources.
