The hierarchy model of computer network security assessment was constructed in the light of the characteristics of computer network and the factors influencing the network security. The fuzzy analytic hierarchy process based on triangular fuzzy numbers was applied to assess the network security quantitatively. Final results of the example indicate that the fuzzy analytic hierarchy process is an exploratory...
Network threat frequency forecasting is the important factor for dynamic quantitative risk assessment, which can timely offer network security administrators the corresponding effective security strategy to actively counteract the network threat. This paper first reviews current time series forecasting methods, and then presents a network threat frequency forecasting algorithm based on fuzzy time...
The anonymity and dynamic characters of p2p (peer to peer) system makes p2p become hotbed with selfish and vicious action. In order to solve the problem of node cheating caused by high dynamic property of P2P, this paper designs a security trust model -- BGTR based on the idea of probability model and fuzzy mathematics. The scheme adopts a new query method that the inquiry peer initiates the calculated...
