Don,
Have you tried setting encryption on for an rman backup? According to the FM it's suppose to encrypt the output for removable media.

Hi Don,
I'm in the process of researching and developing what will be an open
source, post-database intrusion forensics tool called F.E.D.S. (the
Forensic
Examiner's Database Scalpel) that is capable of extracting information
and
row data, deleted or otherwise, from datafiles and the redo logs. Some
of
this research I've written up in the following papers:
http://www.databasesecurity.com/dbsec/Locating-Dropped-Objects.pdf http://www.databasesecurity.com/dbsec/dissecting-the-redo-logs.pdf
If you're concerned about people gaining unauthorized access to data on backup files you should look to encrypt them (there are a number of commercial and open source solutions available) and store them in a physically secure location.
HTH,
David Litchfield
Is it possible to recover information from an undo datafile? I have been searching for information on securing oracle datafiles and see that there are .dbf file viewers that claim to be able to view/edit/export the contents as text. I am thinking that its not likely to be possible to reconstruct anything usable from an undo datafile.
I know that Oracle 10G has the ability to encrypt the contents of datafiles and store the key in a wallet. We are planning an upgrade in a year but right now I'm having to answer questions about vulnerabilty of backups stored on removable media.
