Securing a NetBook w/ SD card
I have an HP Stream 14 en route and am looking at the storage setup from a security standpoint. In my neck of the woods, laptops are frequent theft targets and I suspect the same would hold true while traveling. These HP stream devices have limited storage space (32GB) which has been an issue for Win10 users doing updates. My suspicion is that the Win10 update issue resulted in a fair number of HP Streams showing up on the refurbished market. The devices also have a full size SD slot that supports SDXC.
I intended to just load the personal data I would need on a particular trip and use IMAP with header cache for email. This looks like a good time to explore/implement encryption. My thoughts: Option 1. An /etc/rc.local command to mount the SD drive as an encrypted /home/user partition. Do not create the /home partition on the MMC. Option 2. At install make a very small /home/user partition. Use an /etc/rc.local script to graft the SD uuid, if present, onto the small MMC /home/user partition. Could this scheme incorporate encryption? Option 3. Encrypt the /home/jsh/mail/cache file Any other suggestions? Last edited by shep; 27th November 2018 at 05:02 PM. |

Seconded. I wouldn't use an SD as an integral storage device on any laptop. It's one thing if this is some arm board where the thing never gets physically touched ever. But one mistake (think: accidentally ejecting the SD card while the machine is running/writing) can totally destroy all the data on the SD card. Not worth it IMO.

I'm not avocating your use of an SDHC card - but my daily email checker runs Linux from an 8GB SDHC card, & I haven't had any problems/mishaps with it.
