FileVault: FileVault is a feature that performs on the fly encryption and decryption of data on your hard drive.. However, this added level of security requires additional processing power. Because of this, it is recommended that FileVault not be used in conjunction with FileMaker Server and your FileMaker databases.
If you're worried about the security of filemaker, use Encryption at Rest, included in the FM15 platform.
You can also use SSL to secure the transmission of data, and use secure container storage as well.
I second what Mike said. Do not use FileVault. Use the encryption available through FMPA15. If you do not have FMPA, anyone with FMPA15 can setup the encryption for you.
SSL should be a must do thing and not really an "also" option. There is a growing list of compatible certificates and it is not a big cost as far as security goes.
Can this be done? What is the down-side?
Potentially, destroying your data. Best practice is never to allow anything - anything - to touch hosted FileMaker files except FMS. I cannot say for certain that FileVault will do that, but ask yourself - is it worth the risk?
Agree with Mike B. and bigtom. Use FileMaker's built-in features for this functionality.
It's the wrong technology for your needs. It's not going to give you any benefits and it comes with considerable costs in performance and risk.
FileVault encryption kicks in when you turn your machine off. A server is designed to be ON. While your server is ON FileVault is OFF.
Run FMS15 and use Encryption at Rest.
In using Encryption at Rest you will be encrypting at the OS level and effectively providing the same security. Don't forget to use Secure External Container storage too for binary files in container fields. And of course get a 3rd party SSL certificate to verify the server in addition to providing SSL encryption between the client and server.
Do not use FileVault.... as Malcolm Fitzgerald said... wrong technology to achieve what you are trying to accomplish.
Thank you to all you geeks for your help.
