NAS + disk encryption


Hi all,

Does anyone know a good solution to build a NAS system with strong disk encryption? I was going for FreeNas because of its good reviews but disk encryption isn't supported yet.

Any help appreciated

A few questions if I may:
What should this encryption safeguard against?
How transparent must it be to use wrt accessing applications and users?
Does this encrypted data get served over insecure protocols?
Does this encrypted data get stored remotely (temporarily) in insecure ways?

Thank you for your answer unSpawn.

The nas system should a least encrypt all hard disks. It will only contain data.
I don't intend right now to make it accessible over the internet (ftp or so) just access it localy.
I will be the only user. Data isn't stored remotely.

Basicaly I work on my computer and when I'm done I just want to transfer the files to the NAS system and make sure that no one can access those files even if the hard disks are retrieved.

If you are going to invest time using disk encryption then you need to to guard that investment by hardening server and clients so nobody can snoop data, get access to files in a decrypted state ("working" means there's a high probability data will reside (client-side) on disk, in memory and probably in swap as well), regularly auditing the system for intrusions or integrity problems and choosing a fitting backup strategy.


Here's some selected LQ (search) threads for you to read on disk encryption. Please read *whole* threads (except the first link). Basically these include links to HOWTO's, handle Dm-crypt and mention other stuff like Truecrypt:
Is it possible to TRULY hide a partition / data?

filesystems & encryptions
Encrypting harddrive
disk encryption
* BTW, if whole-disk encryption isn't necessary and you don't need near-military-grade encryption then there are other ways too like for instance FUSE/EncFS.
