ORCEF: Online response cost evaluation framework for intrusion response system

摘要: Abstract Response cost evaluation is a major part of the Intrusion System (IRS). Although many automated IRSs have been proposed, most them use statically evaluated responses, avoiding need for dynamic response cost. However, by designing responses we can alleviate drawbacks static model. Furthermore, it will be more effective at defending system from an attack as less predictable. A model offers best based on current situation network. Thus, positive effects and negative impacts must computed online, time, in We evaluate online with respect to resources dependencies number users. In this paper, present practical framework relevant factors evaluation. The proposed platform that leads us account user׳s needs terms quality services (QoS) critical processes. Compared other models, consists not only novel mechanism complex network topologies, but also detailed effect impact. addition, discuss main challenges type.
