Which access method follows the principle of least privilege for a shared network drive used by the Accounting department?

The principle of least privilege dictates that users should only have the minimum level of access necessary to perform their job functions. By granting appropriate permissions exclusively to users in the Accounting department for both the share and NTFS, the configuration ensures that only those individuals who require access to the shared network drive can access it. This means that they can read, modify, or manage files as needed, while users from outside the Accounting department are completely restricted.

This approach protects sensitive financial data from unauthorized access, minimizing security risks and ensuring compliance with data protection policies. It effectively balances functionality for authorized users while safeguarding resources from potential misuse or inadvertent changes by unauthorized users.

Other options do not align with the principle of least privilege as they either provide excessive permissions or do not adequately restrict access for unwanted users.
