Hi

This is going to be a very dumb question, straddling database and Linux security. 

Given the provisos of the subject, and by minimal I mean NO application code changes (so no use of DBMS_CRYPTO) unless at the highest level or on the smallest set of columns, are there any recommendations, strategies, documents, publications for encryption or other ways (obfuscation, masking) of enhancing security on an RHEL4-6 . Oracle 10g . Standard Edition . 24/7 . application database accessed by users with a networked Java client ?  Without code or metadata changes ?  Or does one just have to bite that bullet ?

Can the Oracle database files be encrypted for such a working, on-line system ?  What will be the performance impact ?  Get empirical I'm sure !  We have en/de-crypted database files for database server transport.

Howdy, Stranger!
