This paper presents the evolving security model and philosophy of TOP, the Trusted ONTOS Prototype. TOP is being designed as a multilevel, high integrity, client/server object database management system as an extension of the existing commercial ONTOS product. TOP will provide features and assurances comparable to those defined for the B1 level of the US TCSEC.
