6.3.1 NAS File System security styles
There are three security style options that can be applied to a NAS File System:
UNIX Controls file access using UNIX permissions in all protocols. A client can change permissions
only by using the chmod and chown commands on the NFS mount point. You can also specify
the UNIX permissions for files and directories created in the file system by Window clients. See
About UNIX Permissions for Windows Directories and Files. With UNIX file security style,
Windows clients cannot change any file or directory permissions. Read and write access is
controlled by the UNIX permissions for Windows files and directories, which you set in Group
Manager.
NTFS Controls file access by Windows permissions in all protocols. A client can change the
permission and ownership by using the Windows Security tab. With NTFS file security style, all
access permissions are controlled by the Windows administrator by using access control lists
or share level permissions.
Mixed Supports both NTFS and UNIX security styles. The permissions and ownership for a file or
directory will be the last one set. Permissions and access rights from one protocol to another
are automatically translated. Mixed is a combination of NTFS and UNIX security style. A
Windows user can override UNIX user settings, and a UNIX user can override Windows user
settings.
