What security model addresses the integrity of data with applications, but is not concerned with security levels and confidentiality?
Explanation
Answer: D - The Biba model addresses the integrity of data with applications, but is not concerned with security levels and confidentiality. Since the Biba model is not concerned with security levels and confidentiality, it does not base access decisions on lattice security levels. Instead, it uses lattice of integrity levels. The goals of integrity modes are to prevent unauthorized users from making modification, to prevent authorized users from making improper modifications, and to maintain internal and external consistency. The three main rules of Biba is the *-integrity axiom in which a subject cannot write data to an object at a higher integrity level, that subject cannot read data from a lower integrity or simple integrity axiom, and that a subject cannot request service to subjects of higher integrity or invocation property.
