Lesson 1: Understanding NTFS Permissions
You use NTFS permissions to specify which users and groups can gain access to files and folders and what they can do with the contents of the file or folder. NTFS permissions are available only on NTFS volumes. NTFS permissions are not available on volumes that are formatted with FAT or FAT32 file systems. NTFS security is effective whether a user gains access to the file or folder at the computer or over the network. The permissions you assign for folders are different from the permissions you assign for files.
After this lesson, you will be able to
- Define the standard NTFS folder and file permissions.
Estimated lesson time: 5 minutes
NTFS Folder Permissions
You assign folder permissions to control the access that users have to folders and to the files and subfolders that are contained within the folder.Table 14.1 lists the standard NTFS folder permissions that you can assign and the type of access that each permission provides.Table 14.1 NTFS Folder Permissions
| NTFS folder permission | Allows the user to |
|---|---|
| Read | See files and subfolders in the folder and view folder ownership, permissions, and attributes (such as Read-Only, Hidden, Archive, and System). |
| Write | Create new files and subfolders within the folder, change folder attributes, and view folder ownership and permissions. |
| List Folder Contents | See the names of files and subfolders in the folder. |
| Read & Execute | Move through folders to reach other files and folders, even if the users don't have permission for those folders, and perform actions permitted by the Read permission and the List Folder Contents permission. |
| Modify | Delete the folder, plus perform actions permitted by the Write permission and the Read & Execute permission. |
| Full Control | Change permissions, take ownership, and delete subfolders and files, plus perform actions permitted by all other NTFS folder permissions. |
NTFS File Permissions
You assign file permissions to control the access that users have to files. Table 14.2 lists the standard NTFS file permissions that you can assign and the type of access that each permission provides.Table 14.2 NTFS File Permissions
| NTFS file permission | Allows the user to |
|---|---|
| Read | Read the file, and view file attributes, ownership, and permissions. |
| Write | Overwrite the file, change file attributes, and view file ownership and permissions. |
| Read & Execute | Run applications, plus perform the actions permitted by the Read permission. |
| Modify | Modify and delete the file, plus perform the actions permitted by the Write permission and the Read & Execute permission. |
| Full Control | Change permissions and take ownership, plus perform the actions permitted by all other NTFS file permissions. |
Lesson Summary
In this lesson, you learned that you use NTFS permissions to specify which users and groups can gain access to files and folders, and what these permissions allow users to do with the contents of the files or folders. NTFS permissions are available only on NTFS volumes. NTFS security is effective whether a user gains access to the file or folder at the computer or over the network. The folder permissions are Read, Write, List Folder Contents, Read & Execute, Modify, and Full Control. The file permissions are similar to the folder permissions. The file permissions are Read, Write, Read & Execute, Modify, and Full Control.
