This paper describes a security model for object-oriented systems. The model supports a flexible data classification policy based on inheritance. The classification poligy allows for a smooth transition between rigid classification rules and unlimited polyinstantiation. The security model treats the data model as well as the computational model of object-oriented systems allowing more flexibility. This model trades an increase in complexity for a more flexible security model.
