To view if a file or folder is using inherited permissions, look at the Advanced Security settings in the Permissions entries window. The Inherited From column will show where the permission has been inherited from or state <not inherited> if it is not inherited. To remove inherited permissions for a file or folder:
Right-click the file or folder and select Properties. Click the Security tab and select Advanced. Click Change Permissions in the Permissions tab. Uncheck the box named Include inheritable permissions from this object’s parent. Read the Windows Security warning and select the appropriate option:
To restore inherited permissions for a file or folder from the parent folder: Right-click the file or folder and select Properties. Click the Security tab and select Advanced. Click Change Permissions in the Permissions tab. Check the box next to Replace all child object permissions with inheritable permissions from this object Click Yes in the Windows Security prompt.
The Owner tab in Advanced Security settings displays the current owner of the file or folder. The owner of the resource has the right to allow or deny access to that resource. In other words, the owner has full control of the resource.
The owner, by default, is the creator of the file or folder. The owner also has power to remove all user and group access to a resource in which case no one will be able to access it. This can be overridden by another administrator or anyone in the Restore Operators group by taking ownership of the resource.
Allowing administrators and members of the Restore Operators group access to take ownership of a resource is a good idea in case a resource is locked out. However, it may be used to force access to an unauthorized user. For instance, a hard drive is taken from a computer. Once it is booted into another Windows instance, the user can take ownership and access the entire file. This is one of the flaws of NTFS and can be mitigated by using full disk encryption.
To take ownership of a file or folder: Ensure you are logged in as an administrator, backup operator, or restore operator. Right-click the file or folder and select Properties. Click the Security tab and select Advanced. In the Owner tab, select Edit. Select the user to make the owner in the Change owner window or click Other users or groups and add a user or group to be the owner. Select Replace owner on sub containers and objects if required. Click OK.
The Effective Permissions tab lists a user’s effective permissions for the selected file and resource. Simply click Select… and choose a user or group in any location to see what permissions that object has on the selected resource. This is good for troubleshooting access issues.
