Settings and management of share permissions and NTFS permissions

What does it matter when an object, such as a folder, uses both share permissions and NTFS permissions?

Shared and NTFS permissions are available only when the shared resource is stored in a partition that uses the NTFS file system. Share permissions become the first line of defense when you have shared and NTFS permissions at the same time. Access to a shared resource account will first be subject to shared permissions, and share permissions will define the maximum access to the shared resource for the login account. As the second line of defense NTFS permissions, this permission can define fine-grained permissions.

When share permissions for a shared resource, such as the ABC folder, are the same as the NTFS permission settings, the two permissions will not affect each other, such as when the Everyone group has read permissions. When two permissions are conflicting because of a setting, the more restrictive permissions are taken, and the difference between the 3 different combinations of share permissions and NTFS permissions, as shown in the table, is the last actual permissions that the account has.
