Communications Server 2007 R2
Topic Last Modified: 2009-03-09
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.
