Explanation

The Clark-Wilson model was designed specifically to enforce data integrity in commercial environments. It does this through two key mechanisms: well-formed transactions (data can only be modified in constrained, predefined ways) and separation of duties (no single user can perform all steps of a sensitive transaction). Unlike Bell-LaPadula which focuses on confidentiality, or models addressing availability, Clark-Wilson is concerned with preventing unauthorized or improper modification of data, making integrity its core focus.
