I have a Synology NAS. It has the possibility to encrypt folders. I have enabled it via the web interface. But one of the reasons for actually encrypting these files is that they should be protected even if if someone steals my NAS. I have mounted the drive on the NAS via the web interface.
What happens when the power is cut and the NAS boots again? Is the folder automatically mounted again? Is the key stored in volatile memory, in flash memory or on the hard disk? If it is stored in volatile memory there should be no risk at all.
Compare it to an iPhone. If you enable screen lock, the key is thrown away when activated.
Mounted where? On the NAS itself or on your computer? – terdon – 2013-02-15T21:56:19.317
I have tried to clarify the question. I am worried about when the folder is mounted on the NAS and it get stolen. – Johan Karlsson – 2013-02-17T18:13:36.667
1Why don't you just reboot your NAS and see if it mounts? – terdon – 2013-02-18T14:10:43.177
@terdon I have no real explanation why I did not try this from the beginning. But now I have. It seems that the mount done on the NAS survives a re-boot. This is not exactly what I hoped for. – Johan Karlsson – 2013-02-25T13:14:23.513
1Have a look at the NAS's
/etc/fstab
file, find the entry for the relevant drive and remove theauto
option if present. It might be a good idea to post thefstab
here so we can have a look. – terdon – 2013-02-25T18:14:08.413
