Explain the concept of effective permissions when a user has different permissions at the shared level and the NTFS level.
The effective permissions for a user are determined by combining the Share permissions and NTFS permissions. If a user has different permissions at the shared level and the NTFS level, the more restrictive permissions will take precedence, resulting in the user's effective permissions being limited to the more restrictive set of permissions.
Describe the impact of combining Share and NTFS permissions when a user accesses a shared folder from a different computer.
When a user accesses a shared folder on one computer while logged into another computer, the NTFS permissions are combined with Share permissions to create the user’s effective permissions. This means that the user's permissions will be determined by the combination of both sets of permissions, with the more restrictive permissions taking precedence.
What happens when a user has READ permission at the shared level and MODIFY permission at the NTFS level?
If a user has READ permission at the shared level and MODIFY permission at the NTFS level, the user's effective permission will be limited to READ & EXECUTE. This is because the more restrictive NTFS permissions take precedence over the less restrictive Share permissions.
What are the effective permissions for a user who has CHANGE permission at the shared level but only Read & Execute permission at the NTFS level?
When a user has CHANGE permission at the shared level but only Read & Execute permission at the NTFS level, the user's effective permissions will be limited to Read & Execute. The more restrictive NTFS permissions take precedence over the less restrictive Share permissions.
Study Notes
Effective Permissions: Combining Share and NTFS Permissions
- When a user has different permissions at the shared level and the NTFS level, the most restrictive permissions are applied.
- This is because the system wants to ensure the user has the least amount of access to the resource.
Combining Share and NTFS Permissions
- When a user accesses a shared folder from a different computer, the combination of Share and NTFS permissions determines the effective permission.
- The system applies the most restrictive permission from both levels to ensure the user's access is limited.
Effective Permissions Scenarios
- READ at shared level, MODIFY at NTFS level: The user's effective permission is READ, as the system applies the most restrictive permission.
- CHANGE at shared level, Read & Execute at NTFS level: The user's effective permission is Read & Execute, as the system applies the most restrictive permission.
