Certified Information Systems Security Professional (CISSP) Practice Exam

The Clark-Wilson Model emphasizes the integrity of data and aims to ensure that data is modified only in authorized ways. It specifically addresses integrity goals, which include preventing improper modifications by authorized users and preventing unauthorized modifications altogether. The model employs a set of well-formed transactions and separation of duties to enforce these integrity principles. One of the key aspects of the Clark-Wilson Model is the concept of well-formed transactions, which ensures that only certain authorized users can make specific changes to the data, thereby preventing any modifications that don't comply with the established rules. Furthermore, the model supports maintaining internal consistency through auditing, which allows for monitoring and verification of transaction correctness. However, the aspect of encrypting data for confidentiality is not addressed by the Clark-Wilson Model. While confidentiality is a crucial element of information security, it falls outside the primary focus of this model, which is strictly on data integrity. Encryption is a mechanism used to protect data's confidentiality but does not directly relate to the goal of preserving data integrity as outlined in the framework.
