Abstract :
A security model for a multilevel secure object-oriented database (SODA) is described. The author demonstrates that the model satisfies the simple security condition and the *-property. Data classification is based on inheritance with the enforcement of data classification rules assured by the TCB. SODA allows the use of polyinstantiation or rigid classification as a solution to the multiparty update conflict problem with the selection being made on a class by class basis. The SODA model is compatible with a property called modifiability. This property insures that every object which is reachable within the database can be modified by some subject
