You work for a small city IT department and are giving a presentation on correct employee computer and network use to a group of new hires. You are currently describing various security issues in relation to the Internet and are describing a type of attack directed at a server computer by a massive number of computers for the purpose of making the services provided by that server unavailable. What are you describing?

A. DoS

B. DDoS

C. Rootkit

D. Grayware

Solution

B. DDoS (Distributed Denial of Service) is the type of attack which is being describing. DDoS is nothing but a type of attack in which more than one computer is being used to attack a single server, so that the services provided by that server will be unavailable.

If the attack only involves one computer then this kind of attack is known as DoS. Here this is not the case.

Here the other options Rootkit is software tool used to get unauthorized access to a system, and Grayware is some kind of a malware.
