Security in an object-oriented database

Abstract

Translate Article

Much of the research in security for object-oriented databases follows the traditional lines of discretionary access control, mandatory access control, and multilevel secure database systems. In this position paper, our premise is that security and integrity can be implemented in the object-oriented database model. We propose extensions to the basic data model to incorporate security and integrity. Our secrecy/integrity mechanism is based on the idea that objects are partitioned into protected groups. An object in a protected group is restricted in the messages it can accept and send.
