Question

Which access control model uses the simple security rule, the star property rule, and the strong star property rule?

A) Chinese Wall model
B) Bell-LaPadula model
C) Biba model
D) Clark-Wilson model

Answer 1

The Bell-LaPadula model uses the simple security rule, the star property rule, and the strong star property rule to govern information flow and enforce confidentiality in a computer system.

Step-by-step explanation:

The access control model that uses the simple security rule, the star property rule, and the strong star property rule is the Bell-LaPadula model.

The Bell-LaPadula model is a mathematical model that governs information flow in a computer system. It is designed to enforce confidentiality and prevent unauthorized access.

The simple security rule states that a subject cannot read data at a higher security level (or sensitivity) than its own, while the star property rule and the strong star property rule prevent information from being written to a lower security level. These rules ensure that information can only flow in a downward direction, maintaining confidentiality.
