Question

Quizplus · Accepted Answer

A denial of service (DoS) attack floods a network with useless information or with frames or packets containing errors that are not identified by a particular network service. This effectively makes the network or service unavailable to legitimate users, hence the term "denial of service." A virus and buffer are not specific to this type of attack, and port scanning is used to identify open ports on a system or network, not to interfere with access.
