MU Ya-li, Hao Zeng, Xin Liu · Journal of Naval University of Engineering · 2006
By the study of the present multilevel secureDBMS architectures and their policy models,and the analysis of their shortages,this paper presents an improvedMLS-DBMS structure based on the kernelled architecture.On the basis of current policy models,an extended security level security model is given.The model not only improves its flexibility but also enhances the securityand usabilityof the system.
