SnapTrees and Security Models
Volumes and directories created on the root of a volume are assigned one of two
security models: Windows/Mixed or UNIX. The security model determines the
rules regarding which security personality will be present on files and directories
created by the various protocols and clients, and whether the personality of files
and directories can be changed by changing permissions. These directories are
referred to as SnapTrees.
• Creating a SnapTree Directory —
SnapTree directories are created either from the
Security > SnapTrees
screen in the Administration Tool or from a client from any
of the network protocols. SnapTrees created either by clients or in the Web UI
will default to the security model of the parent volume.
Note
The security model of a SnapTree directory may differ from the personality
of the directory (a Windows/Mixed SnapTree may have the UNIX personality,
and vice-versa).
• Toggling Security Models —
The security model applied to a volume or SnapTree
directory can be changed from the
Security > SnapTrees
screen, or when creating
a share pointing to a volume root or SnapTree directory. When changing security
models, the corresponding personality (i.e., Windows for Windows/Mixed and
UNIX for UNIX) is applied to the SnapTree directory itself with a default
permission, and can optionally be propagated with a default permission to all
files and directories inside the SnapTree.
Share Access
Share-level access allows users/groups/clients to connect to a share
and is configured from the
Security > Share Access
screen. Users and
groups known to the system can be given Full Access or Read Only (R)
access to the share.
Share NFS
Access
The Administration Tool provides a window into the
exports
file for
defining how a share is exported to NFS clients.
File Permissions
File-level permissions define what actions users and groups can perform
on files and directories, and are set from a Windows client for a
Windows SnapTree; and from a UNIX/Linux client for a UNIX SnapTree.
