<div><p>Directory and file-level security is available for UDF volumes.
|
|
The system maintains the data authorities of optical directories
|
|
and files for three groups of users; owner, group, and public. Volume level
|
|
security is also available through authorization lists. </p>
|
|
<p>Directory and file-level security is not guaranteed when volumes are removed
|
|
and transported to and from other systems. Security information recorded in
|
|
the UDF structures on the media may not have the same meaning on another system
|
|
as it does on the system where it was written.</p>
