One thing to add to this: Encryption keys are stored in memory (or else it doesn't work) |
| 65 |
This can also be leaked to disk (SWAP, for instance). |
| 66 |
|
| 67 |
I tend to either encrypt it all (apart from the boot partition) or don't bother at all. |
| 68 |
For me, it depends in how and where the system is used. Laptops travel with me and if they can be physically compromised, they get reinstalled with a fully new encryption key. Normally, the laptop is fully switched off when nog in use and the boot process, on the encrypted section, will check the boot partition with a known clean state. If it fails that check, there is a big warning and several services will fail to start. |
