Self Destructing Solution needed

Post Posted: Nov 18, 16 21:09

Hello all,

does anybody know a reliable self-destructing solution for harddrives in a RAID bunch?

Customers requirement: delete all data on all drives incl. OS within shortest time possible
Data volume: 25 TB data on several SSD drives, combined in a RAID 10 array
All files are already encrypted by the OS and the RAID controller is managing the RAID array.
OS is RedHat Enterprise Linux.

Alternative solution: destroying the private encryption keys and relying on the drive encryption only. In this case, even a highly professional APT group should not be able to break the encryption within one year.

Possible alternative solution: physical self-destruction- does anyone know a reliable solution, perhaps based on thermite to cut through the bunch of SSDs?
In all cases, the destruction should be easy to start.

I know there are some solutions likes those www.controlsystemsinte...feworx.htm here or self-destructing USB devices...but opening the chassis with a screw driver and pressing several buttons on the top of every hard disc is not an option. And the solution must work with SSDs in a RAID array and - as far as i have seen - the already existing solutions do not work in conjunction with SSDs or RAIDs.

Any idea or already made practical experiences? I thought of a script to re-initialize the RAID controller to factory settings, started from the Linux OS via sudo...

best regards,
Robin

As I see it (but of course I may be wrong) solutions *like* thermite or electrically zapping the devices (a tad bit "safer" than thermite) represent a big risk.

They may be triggered accidentally.

Now the issue is - provided that the data has some relevance - to be "safe" from accidental wiping, you need a backup, and once you have a backup, it should also be destroyed at the same time the original is (Catch 22) Shocked .

Also, both the "thermite" or the zapping would need a separate, safe, reliable electrical source, separated from mains, for the thermite even a small UPS would do, of course.

Crazy as it might seems, push-button self-destroying SSD's do exist (or existed):

Though I believe that any SSD can be electrically zapped by applying to it enough voltage/current (you will blow also the PSU, very likely, but that isn't really a problem).

For all that matters, you can have the case over a thick steel plate and under a suspended load and unhook the load in case of need.
I know it sounds a lot like a Wile E. Coyote solution, by ACME Wink but if you think at it more as a sort of manual drop hammer:

it starts making some more sense.
