Data base security: requirements, policies, and models
Christopher Wood, Eduardo B. Fernández, Rita C. Summers · IBM Systems Journal · 1980
We have indicated some of the wide range of security policies an enterprise may wish to implement, and we have described models that could be used in designing a data base systemfl exible enough to support many of those security policies. Additionally, we have shown how models can be used for the formal specification of data base access rules and in comparing the security features of existing data base systems.
