....(relation produced by the wrapper) at the source has associated a security level. In case of ner grained classi cation, the level assigned to each object will be the greatest lower bound of the security levels of the information in the object, as is common practice in mandatory security policies [9]. As described in Section 5, the security level associated with the object is the level that will be considered by the mediator to lter access requests to the object. Finer grained access control (within the object) will be enforced at the source itself. 4. Application schema de nition and ....

....(standing for a specific access request) in their logic is fully abstract (i.e. uninterpreted) 1, p. 725] In some sense, our work is complementary to theirs in that we investigate the structure of these statements and provide meanings to them. Lastly, concrete models such as those proposed in [8, 15, 24] address the same general concerns as ours, but for application specific domains. Our framework can be used as a general basis underlying their respective specific proposals. 3 Three Types of Structural Properties Authorization requirements are highly structured because the set of subjects and ....

....abstract security properties of a system as a whole, which includes authorization as a key component. The papers by Abadi, et al. 2] and Lunt [19] are similar in spirit to ours, in that their focus is on understanding the semantics of authorization. Concrete models such as those proposed in [6, 12, 18] address the same general concerns as ours, but for application specific domains. Lastly, our composition operators are designed for authorization requirements, and are different from the one in [20] which is designed for a particular notion of security. The balance of this paper is organized as ....

See, for example, the MMS model [10] 9.
