We're setting up a XF instance for a small private group of collaborators and I'm hoping to take as many precautions as possible to secure the data. Hence, I'm looking into the possibility of installing TrueCrypt on the server in order to encrypt the attachment directory. But I have no idea where forum data is stored and whether I can also encrypt or protect this data in any other way. Does anyone have any experience with methods for securing forum content, as I'd be interested in your various solutions. By the way, we're installing an SSL cert so that all page is done over https. But that doesn't protect the data if the server is compromised.
