Certified Information Systems Security Professional (CISSP) Practice Exam

The primary goal of the Clark-Wilson Model in information security is to prevent unauthorized modifications to data. This model is specifically designed to ensure data integrity and security through well-defined rules and procedures. It emphasizes the importance of maintaining the accuracy and reliability of data by enforcing strict access controls and validation checks. In the Clark-Wilson Model, user access is controlled through the concept of transformation procedures, which define how data can be modified and by whom. Only authorized users are allowed to perform specific transformations, thus ensuring that data modifications are legitimate and recorded properly.

The other options do not align with the main focus of the Clark-Wilson Model. Enhancing user experience, facilitating data sharing, and improving system performance may be important objectives in various contexts, but the core principle of the Clark-Wilson Model centers around preventing unauthorized changes to maintain data integrity. This is achieved through a clear set of rules and a separation of duties, which further bolsters the integrity of the system.
