Final answer:
The Brewer and Nash model, also known as the Chinese Wall model, primarily protects against unauthorized disclosure of sensitive information by preventing conflicts of interest in data access.
Step-by-step explanation:
The Brewer and Nash model, also known as the Chinese Wall model, is a security model designed to protect against conflicts of interest by prohibiting one person from accessing multiple conflict-of-interest categories. It is specifically tailored to prevent unauthorized disclosure of sensitive information. Its main goal is to allow a consultant to work for multiple clients in the same sector without conflict while preventing access to potentially sensitive competitive information. The Brewer and Nash model does not specifically address data integrity, availability threats, or unauthorized access to the same extent as its primary function of conflict of interest mitigation.This model ensures that only authorized users are allowed to access sensitive information and prevents unauthorized users from gaining access to it. It also protects against unauthorized disclosure by enforcing strict access controls and encryption techniques.However, it is important to note that the Brewer and Nash model does not specifically protect against data integrity or availability threats.
