DoS Attack Impact Assessment based on 3GPP QoS Indexes

Attack impact assessment is an important research in attack test and evaluation. Focusing on the end users´ actual quality of service, a user-centric DoS attack impact assessment model based on 3GPP QoS indexes has been proposed. This model is a threedimensional denial of service degree assessment model.Based on the model one arithmetic has been proposed to measure the degradation of one service´ QoS. Experiments demonstrate that the threedimensional DoS attack impact assessment is simple and can capture the quality of service of end user.
