It is this transparency of access combined with intelligent policy rules that act on file attributes
(brought about by advanced, network-centric appliances) that can provide unified views across heterogeneous file servers regardless of location, and it is this new breed of network-centric NFM solutions that can unlock the power of NAS for the enterprise.
Changing file attributes
can be done through the SecretDisk software itself.
Search-engine-like, browser-based and application-embedded interfaces enable users to search beyond naming conventions, meta data and file attributes
to retrieve information from deep within a file, regardless of its content, format or location.
Accordingly, an organization should implement the same type of security strategy that it would for any other type of computing platform on the network: strong passwords, file and directory level encryption, protection from attacks via outside networks, and security for file attributes
and directory-level settings.
The move policies or scripts must ensure that all file containers are rejoined with the files already migrated to the target NAS volumes and all file attributes
(i.e., owner, last modified/accessed, etc.) are properly recreated.
can be set on a user by user basis to control: copying of .EXE or .COM files; Floppy reads and writes; Absolute Disk I/O (which protects against viruses, formatting, deleting, altering and penetration by Norton Utility type programs); and changing file attributes
marked read only and hidden (or security system files).
However, this approach can be complex in a majority of enterprise-class environments that have a large number of files, changing file attributes
, users and associated crypto keys.
volumes, between file content and file attributes
, or within file system metadata.
Files enter the SAN from the IP network, where Storage Tank logs metadata information for file attributes
and locations, and enables file locking.
Major file system semantic distinctions that exist between Unix and NT--in the way Unix and Windows/NT handle semantics for filenames, file attributes
, shared file-locking techniques and their respective file security subsystems--are not resolved by CIFS/SMB and NFS file-sharing protocols.
