Self-protecting Objects in a Secure Federated Database.
Martin S. Olivier · DBSec · 1995
This paper presents an implementation strategy for a secure federated database. A federated database is a distributed database with a relatively high degree of site autonomy. The proposed implementation strategy assumes that a federal security policy specifies the security aspects that apply to all sites of the federation. Each site is then able to extend the security policy that applies to data owned by it with its own site security policy. The site security policies are guaranteed to be enforced even if an object of one site is relocated to another site.
