Botnet

In which form of authentication does the authenticating device generate a random code and send it to the user who wants to be authenticated?

Challenge/Response

Which of the following is NOT information that a packet filter uses to determine whether to block a packet? IP Address Checksum Protocol Port

Checksum

An attack in which many computers are hijacked and used to flood the target with so many false requests that the server cannot process them all, and normal traffic is blocked.

DDoS Attack.

A semi trusted subnet that lies outside the trusted internal network but is connected to the firewall to make services publicly available while still protecting the internal LAN.

DMZ.

T/F: A packet monkey is an unskilled programmer who spreads viruses and other malicious scripts to exploit computer weaknesses.
