An Amplification Attack is any attack where an attacker is able to use an amplification factor to multiply its power. Amplification attacks are "asymmetric", meaning that a relatively small number or low level of resources is required by an attacker to cause a significantly greater number or higher level of target resources to malfunction or fail. Examples of amplification attacks include Smurf Attacks (ICMP amplification), Fraggle Attacks (UDP amplification), and DNS Amplification.
