FFSN is one of the enormous threats of internet. It can hide the attackers behind a group of agents and by this way the attackers can avoid being detected. The benefit of FFSN to attackers is the malicious websites can be protected and the survival time can be prolonged. The danger of FFSN is getting more serious and Flux-Agent could be a Bot note. To estimate the size of FFSN can find the danger degree but to estimate the size is not easy. The purpose of this study is to estimate the group size of Fast-Flux Service Network (FFSN.). Uses Joint hypergeometric maximum likelihood estimator(JHE)of Capture- Recapture Method(CRM)to estimate the group size of Flux-Agent. By computing the joint hypergeometric maximum likelihood estimator(JHE)of Program NOREMARK, the group size can be found. The experiment result can find the group size more quickly than census. |
