A. B. C. D.A.
The principle of least privilege is a security concept that states that a user should be granted only the minimum access necessary to perform their job duties. This reduces the risk of accidental or intentional misuse of sensitive information and resources.
Option A is the correct answer because it follows the principle of least privilege. By granting appropriate permissions only to users in the Accounting department for both the share and NTFS, other users will not be able to access or modify the files. This limits the possibility of unauthorized access or modification of sensitive accounting information.
Option B grants full control permissions to all users for the share only, which could lead to unintended changes or deletion of files. This violates the principle of least privilege because all users do not need full control permissions to the Accounting department's files.
Option C grants full control for the share and appropriate NTFS permissions to the Accounting department. Although this is more secure than option B, it still violates the principle of least privilege because users outside the Accounting department could still have access to the share.
Option D grants modify permissions to the Accounting department and denies NTFS permissions to all other users. This option is not secure because it does not follow the principle of least privilege. Users outside the Accounting department should not be denied access to the share, especially if they have a legitimate business need to access the files.
Therefore, option A is the most secure option as it follows the principle of least privilege by granting appropriate permissions only to users in the Accounting department for both the share and NTFS.
