Question

Which attack involves the use of multiple computers with the purpose of denying legitimate access to a critical server?

a) Land attack
b) Ping of Death attack
c) Denial-of-service (DoS) attack
d) Distributed denial-of-service (DDoS) attack

Answer 1

A Distributed Denial-of-Service (DDoS) attack is the correct answer, where many computers overwhelm a server with traffic, denying service to legitimate users.

Step-by-step explanation:

The attack that involves the use of multiple computers to deny legitimate access to a critical server is known as a Distributed Denial-of-Service (DDoS) attack. This type of attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such attacks typically involve more than one—and often thousands of—unique IP addresses. The influx of incoming messages to the target system essentially forces it to shut down, thereby denying service to legitimate users.
