Brewer-Nash Model

Correct Answer: Chinese Walls

The correct answer is 'Chinese Walls.'

In the Brewer-Nash Model, also known as the Chinese Wall Model, Chinese Walls are the primary mechanism for managing information flow between different organizational units. This model is specifically designed to prevent conflicts of interest in organizations by creating logical barriers between different departments or units.

Chinese Walls are conceptual barriers that restrict the flow of information between different parts of an organization. They are particularly important in financial institutions, consulting firms, and other organizations where maintaining confidentiality and preventing conflicts of interest is crucial.

The other options are incorrect:

'Data Sanitization Protocols' are important for data protection but are not specifically related to managing information flow between organizational units in the Brewer-Nash Model.

'Conflict Resolution Mechanisms' may be used to address conflicts after they occur, but they are not the primary method for preventing information flow between units in this model.

'Dynamic Access Control Lists' are a general security mechanism for controlling access to resources, but they are not specific to the Brewer-Nash Model or primarily responsible for managing information flow between organizational units.

The Chinese Wall concept is fundamental to the Brewer-Nash Model and is the key element in preventing unauthorized information flow between different parts of an organization, making it the best answer to this question.
