摘要: abstractInternet-based computer information systems play critical roles in many aspects of modern society. However, these are constantly under cyber attacks that can cause catastrophic consequences. To defend effectively, it is necessary to measure and predict the effectiveness defense mechanisms. In this article, we investigate how an important mechanism known as early-warning. This turns out be a challenging problem because must accommodate dependence among certain four-dimensional time series. course using dataset demonstrate prediction methodology, discovered new nonexchangeable rotationally symmetric structure, which may independent value. We propose vine copula model newly show early-warning more accurately than others. also discus...
