When you use TDE, the keys will typically be stored on the machine in the so-called Oracle e-Wallet. While Oracle has taken it as far as they can with a software solution (and they've done a brilliant job), storing keys in software isn't best security practice because you shouldn’t keep the key and the database in the same place. When you back up the machine, the key will be backed up with the database. Also, you will find it difficult to demonstrate a separation of duties between database security administration for compliance.

Oracle 11g supports the use of hardware security modules (HSMs) that protect the keys, separate security and DB administration, and ensure that keys are never stored with the data. HSMs will also offer you to manage keys across database servers, reducing your total cost of ownership.
I work for Thales e-Security (formerly nCipher), who offers such a solution. If you’re interested, please check out: http://www.ncipher.com/en/Solutions/Business%20Solutions/Databases.aspx

Comments are moderated, and it looked like there were two identical comments, so this is the second one that was posted. Thanks for your input. I'd really like to see more discussion going on here so people can interact directly with Priority Support, other parts of Oracle and the largest group of Oracle experts in the world--our customers.
