The Brewer-Nash security model is also known as which of the following? Response:

MAC (Mandatory Access Control) is a security model where the operating system restricts access to objects based on sensitivity and user clearance, which differs from conflict of interest prevention.

The Brewer-Nash security model, often called the Chinese Wall model, is specifically designed to enforce conflict of interest policies, ensuring that users cannot access information that would create a conflict of interest. This model dynamically changes access permissions based on a user's previous access history to data sets belonging to competing companies.

Preventive measures is a general term for security controls and not a specific security model name.

RBAC (Role-Based Access Control) grants access based on user roles within an organization, distinct from conflict of interest enforcement.
