What does the Chinese Wall Model aim to prevent?

The Chinese Wall Model is a security model designed to prevent internal conflicts of interest, particularly in environments where users have access to sensitive information related to competing entities. This model is especially relevant in industries like finance and law, where the same individual may have access to confidential information about multiple clients or competitors.

The structure of the Chinese Wall Model prohibits individuals from accessing data of clients after they have engaged with a competing client, thus preventing scenarios where a conflict of interest might arise. This model ensures that users can only access information that aligns with their current work context or that does not create a conflict, thereby maintaining the integrity of sensitive data and preserving professional ethics within the organization.

Other options focus on distinct aspects of information security. Data breaches from external threats and unauthorized access to sensitive information are generally mitigated by different security controls and access management practices, while data corruption during transmission is addressed through integrity checks and encryption. However, the unique focus of the Chinese Wall Model is specifically on managing and preventing internal conflicts of interest among personnel who have access to information related to competing interests.
