Defense system model based on trust for cloud computing
Jiong Yu · Journal of Computer Applications · 2011
Because of the cloud computing's characteristics of being dynamic and open,continuous malicious attacks happen frequently.With the idea of trusted cloud,a defense system model based on trust for cloud computing was constructed to guarantee the cloud security.Through real-time monitoring,users' behavior evidences could be obtained and standardized;a new method for users' trust evaluation based on fuzzy Analytic Hierarchy Process(AHP) was presented,which gradually determined the weights of behavior evidences,achieved quantitative assessment of behavioral trust;so as to provide great security defense for users.Besides,multiple detection engines were used to conduct a comprehensive inspection of suspicious files and to make integrated decisions.The experimental results show the system model can effectively eliminate the malicious behaviors from undesirable users,reduce users' damages caused by virus and achieve a two-way defense for both cloud and client.
