Some New Security Strategies Description about Grid
The security strategy description is important contents of security access control research about grid. The strategy of traditional access control models has ignored the subject security, and can not be solved with the dynamic grid, and the characteristics of the coexistence of multiple security strategy etc problems. Regarding the concept of subject/ object decomposition and the organization classifications are defined, and the concepts of subject safe service, object safe service, and granularity control etc are expanded, Using the RBAC model and BLP the model basic principle, a group new access control security strategy based on the grid environment have be given in the paper. After discussion shows that the new rules emphasis on the subject security, and adapt to the dynamic nature of grid environment and characteristics of the coexistence of multiple security strategy. The new rules are compatibility with existing network access control model, they are secure and are also an expansion under the common network environment access control strategy, and this has certain positive significance to the grid security research.
