Abstract

The measurement of network congestion and degradation of quality of service during distributed denial of service attacks remained an elusive goal. This paper analyzes the impacts that all congested links cause on attack victim and network architecture, introduces the min-cut set and presents a new method to assess the network security situation under DDoS attacks, which computes the influence value that attacks cause on network security situation according to the distance between the congested link and victim and whether the link is in the min-cut set, and this value is used for quantitative situation assessment. The applicability of this method is verified by simulated experiments with the network simulation tool.
