I still don't understand why they strip memory from machines from a classified setting. Once powered off, the data is only recoverable for a short time.

- grzm 10y agoWhy risk it?
- flukus 10y agoJust in case? If a technique was developed to get information off it tomorrow it would take months/years for department policy to catch up. It could also be a hold over from when memory wasn't so volatile.
- avn2109 10y agoActually this might be evidence in favor of the claim that the NSA has fancy methods for RAM data recovery.

- shakna 10y ago> Once powered off, the data is only recoverable for a short time It comes down to defence-in-depth. That short time is usually between seconds and minutes. A can of compressed air can extend it a bit, but a dip in liquid nitrogen can turn the dial up a long way. Other techniques may appear in the future. You need to trust that one of your own people won't do any tampering to extend the RAM. Much easier to verify there isn't any on the way out the door.
