Permissions
You can assign the following permissions to an NT resource:
■ Read
■ Delete
■ Write
■ Execute
■ Change Permissions
■ Take Ownership
Additionally, you can group these permissions into standard permissions that
consist of one or more previous permissions. These standard permissions
include:
■ No Access
■ Read
■ Change
■ Full Control
■ Special Access (where individual permissions can be selected, such as
Read + Change Permissions)
Sharing Files Across Multiple Platforms Sharing Files Across Multiple Platforms Sharing Files Across Multiple Platforms Sharing Files Across Multiple Platforms
The NAS server was designed to work well in a heterogeneous environment
and support remote file access protocols for UNIX and NT clients. A major
difficulty in sharing data across these environments is that the file system
security models are very different. For example, NT systems that use user-level
security use ACLs to identify both themselves and the permissions for each
data object, whereas UNIX systems use traditional UNIX permissions that
define explicit permissions for the user, group, and other. However, given
some care in setting up the security environment, a reasonable level of access
can be provided for cross-environment requests (i.e., a UNIX client requesting
a file created by an NT client) without overly compromising the security set by
the creator of the object.
