Let assume that the datbase is a standard one such as Oracle or SQL. The
database is loaded into the systems memory decrypted. EFS does not
encrypt database tables. It may encrypt the ENTIRE file, but when the
database is live it is loaded Unencrypted. EFS is thus not the be all
and end all for PCI requirements.
Next, EFS does nothing to help with ensuring backups are secure on tape.
It does nothing to secure the network or internal system transfers.
The idea is that there is no cut and dry solution out of the box. It is
something that requires thought.

Subject: Re: PCI, EFS and the future?
My gut feeling is telling me that EFS is the wrong solution and I fear
that it won't be in compliance with PCI's data at rest specs.
May I ask why you feel that EFS is the wrong solution? On the face, it
seems to satisfy all the PCI data storage encryption requirements ....
I will tell you more why EFS might not be a good idea, but I want to
hear your opinion first.
Here is some white-papers (disclaimer: they are self-serving, but
still good) that cover data storage requirements for PCI.
