Active Directory Shared Folder Permissions – One of the most critical security concepts is permission management: making sure the appropriate permissions are set with users, and that usually means knowing the difference between shared and NTFS permissions. Share and NTFS permissions work completely separate from each other, but ultimately serve the same purpose: to prevent unauthorized access. Get the free Active Directory Environments Testing ebook from feathers. However, when NTFS and share permissions interact, or when a shared folder is in a separate shared folder with different share permissions, users may not be able to access their data or may be able to gain higher access levels. than the security administrators intend. Here are the main differences between shared and NTFS permissions so you know what to do. What is NTFS? A file system is a way of organizing a drive, indicating how data is stored on the drive and what types of information can be attached to files, such as permissions and file names. NTFS (NT File System) stands for New Technology File System (NTFS). NTFS is the latest file system used by the Windows NT operating system to store and retrieve files. Before NTFS, the File Allocation Table (FAT) file system was the primary file system in older Microsoft operating systems and was designed for small disks and simple folder structures. The NTFS file system supports larger files and hard drives and is more secure than FAT. Microsoft first introduced NTFS in 1993 with the release of Windows NT 3.1. It is the file system used in Microsoft’s Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000, and Windows NT operating systems. NTFS Permissions NTFS permissions are used to manage access to files and folders that are stored on NTFS file systems. To see what kind of permissions you’ll extend when you share a file or folder: Right-click the file/folder Go to “Properties” Click the “Security” tab. Change and Read which can be configured for groups or individually, NTFS offers a few more permission options: Full Control: Allows users to read, write, change, and delete files and subfolders. Additionally, users can change permission settings for all files and subdirectories. Modify: Allows users to read and write files and subfolders; also allows folder deletion. Read and Run: Allows users to view and run executable files, including scripts. List of folder contents: Allows you to view and list files and subfolders, as well as execute files; inherited only by folders. Read: Allows users to view the contents of the folder and subfolder. Write: Allows users to add files and subfolders, allows you to write to a file. If you’ve ever been involved in permission management in your organization, you’ll eventually encounter “broken” permissions. Don’t worry, they are repairable. Share permissions When you share a folder and want to set the permissions for that folder, it’s a shared resource. Essentially, share permissions determine what kind of access others have to the shared folder on the network. To see what kind of permissions you’ll extend when you share a folder: Right-click the folder Go to “Properties” Click the “Sharing” tab Click “Advanced Sharing…” Click “Permissions” And you’ll navigate to this window: There are three types of sharing permissions: Full Control, Change and Read. Full Control – Allows users to “read”, “change”, as well as edit permissions and take ownership of files. Switch: Switch means the user can read/execute/write/delete folders/files inside the share. Read: Read allows users to view the contents of the folder. A Warning About Share Permissions Sometimes when you have multiple shares on a server that are nested under each other, permissions can get complicated and messy. For example, if you have a “Read” folder in a subfolder share permission, but then someone creates a “Modify” share permission above it at a higher root, you may have people with higher access levels than you intended. There is a way around this, which I will discuss below. How to use share and NTFS permissions together One of the common questions that comes up when you’re setting up security is “what happens when share and NTFS permissions interact with each other?” When you use shared and NTFS permissions together, the more restrictive permission wins. Consider the following examples: If the share permissions are “Read”, the NTFS permissions are “Full Control”, when a user accesses the file on the share, they will be granted “Read” permission. If the share permissions are “Full Control”, the NTFS permissions are “Read”, when a user accesses the file on the share, they will still be granted “Read” permission. Manage NTFS permissions and share permissions If you find that working with two separate sets of permissions is too complicated or time-consuming to manage, you can switch to using only NTFS permissions. When you look at the examples above, with only three types of permission settings, shared folder permissions provide limited security for your folders. Therefore, you get the most flexibility by using NTFS permissions to control access to shared folders. Additionally, NTFS permissions apply whether the resource is accessed locally or over the network. To do this, change the sharing permissions for the folder to “Full Control”. You can then make whatever changes you want to NTFS permissions without having to worry about share permissions interfering with your changes.

You can use group policies to set access rights to directories. or files for multiple computers. They not only save interactive configuration but also ensure that permissions do not deviate from the default settings in the future.

For most directories installed by the operating system, there is usually no need to change permissions. Exceptions are vulnerabilities such as CVE-2021-36934 (“HiveNightmare”), where critical components such as the SAM database are not sufficiently protected due to incorrect configuration of access rights.
In this case, as a workaround, you can change the permissions to a secure state using a GPO on all affected computers. Another use case might be when you create a folder using Group Policy preferences and want to set its access rights immediately.

Another example would be that an application runs under a service account and the account needs access to certain data directories.
Since client-side extensions reapply the settings of a GPO on every update, this ensures that the desired permissions are always maintained, for example on file shares with a deep folder structure. Manual changes will be corrected automatically.
After creating a GPO and linking it to the desired OU or domain, open it in the GPO editor. There, switch to Computer Settings > Policies > Windows Settings > Security Settings > File System. From the File System context menu, select Add File.
This opens a dialog box that can be used to navigate the administration workstation’s file system. This is convenient if the target computers have the same folders. Otherwise, you can enter any path in the Folder input field.

After selecting a directory or file, the Security dialog box (as you know it from the properties of a file system object in Explorer) appears. Here, enter the required principals and assign them the desired permissions. Deleting accounts or groups has the same effect on target systems.
If you open advanced security settings by clicking Advanced, you can configure inheritance there. After confirming the new permissions, you also have the option to replace the existing permissions in all subfolders with inheritable permissions or, if the permissions were assigned there directly, leave them as they are.
Another option, called Do not allow permissions for this file or folder to be overridden, disables the transfer of permissions to subdirectories. In this case, you probably set a separate GPO setting for subdirectory tree permissions.
After restarting the target computers or running gpupdate /force, the affected files or directories should receive the new permissions. When you log on to a local Windows machine (even if a file or folder is shared with other users on your network) and access. an object locally, NTFS permissions are applied and share permissions are not applied.
Folder Access And Permissions
In other words, NTFS permissions are applied to users who log on to the network locally while share permissions are not applied.
No matter how restrictive sharing permissions are on your network, if you have access to the object and are logged on to the workstation or server that “owns” the file or folder, you will be granted
