What aspect of user permissions is crucial for maintaining confidentiality?

Granular control over who can access specific information is essential for maintaining confidentiality because it allows an organization to define and manage user permissions at a detailed level. This means that access can be tailored based on individual roles, responsibilities, or clearance levels. By specifying who can view, edit, or share particular pieces of information, sensitive data can be protected from unauthorized access. This targeted control reduces the risk of information leaks and ensures that only individuals who need access to certain data for their job functions can obtain it.

Other choices do not contribute to confidentiality in the same way. For example, while accessibility across all devices promotes convenience and mobility, it could also increase vulnerabilities if sensitive data is not properly protected on those devices. The ability to create as many users as desired can lead to excessive exposure if not paired with controlled permissions. Open access to all documents undermines confidentiality entirely, as it allows unrestricted viewing of sensitive information by anyone who can access the system. Thus, the focus on granular control stands out as the most effective measure for maintaining confidentiality.
