Subject: Security Issue
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.
