Virtual machine incorporation increases the strength of cloud environment. Flexibility of user depends on easy availability of infrastructure at any instance during the service. This easiness brings many challenges that need to overcome and monitor continuously for the smoothness of cloud service. Out of different cloud issue this paper has resolved on malicious machine detection issue. Trust of virtual machines were evaluated by second order markov model, as per behavior noticed by the centralized datacenter. Trust value of each VM either old or new in cloud were evaluate after a fix time frame. This work dynamically adopt the sequential behavior among the machines as per assign job completion. Proposed model was robust against gray and distributed attacks. Experiment was done in these attacked environment and comparison of proposed model was done with existing techniques. Results shows that proposed second order markov model trust (SOMMT) has higher detection efficiency of malicious VM.
