摘要: In this paper, we build on a recent worm propagation stochastic model, in which random effects during spreading were modeled by means of differential equation. On the basis introduce notion critical size network, is least network that needs to be monitored, order correctly project behavior substantially larger networks. We provide method for theoretical estimation respect with specific characteristics. Our motivation requirement real systems balance accuracy (i.e., monitoring sufficient reduce false alarms) and performance small-scale complexity). addition, run simulation experiments experimentally validate our arguments. Finally, based critical-sized networks, propose logical framework distributed early warning system against unknown fast-spreading worms. proposed framework, parameters an detected are estimated time studying network. way, security enhanced as estimations generated may help large-scale networks respond faster new threats.
