A DoS attack situation assessment method based on QoS

Resource depletion Dos attacks frequently occur in the network, and it is difficult to defend. In order to observe and prevent such attacks, this paper proposed a method of attack situation assessment based on quality of service. The method applies with weight correction algorithm to enhance the objectivity of the algorithm and reduces the error. Experiments show that the proposed assessment method will be able to effectively indicate the attack posture and provide a basis for network administrators to develop response strategies.
