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.
