Powered by the Internet and the ever-increasing level of informatization,the cyberspace has become increasingly complex and its security situa-tion has become increasingly grim,which requires new adaptive and collaborative defense technologies.In this paper,we introduced an extended interactive multi-agent decision model for decentralized cyber de-fense.Based on the significant advantages of the coop-erative multi-agent decision-making,the decentralized interactive decision model DI-MDPs and the corre-sponding interaction and retrieval algorithms are pro-posed.Then,we analyzed the interactive decision by the calculation and update processes of three matrices,the stability and evolutionary equilibrium of the pro-posed model are also analyzed.Finally,we evaluated the performance of the proposed algorithms based on open data sets and standard test environments,the ex-perimental results shown that the proposed work will be more applicable in cyber defense.
