Hello everyone,
I have often heard arguments against only encrypting the partition(s)
containing sensitive data: "data will leak", people tell me, hence you
should really be encrypting the entire system.
I would like to know how exactly it is that "data leaks". Swap is an obvious
suspect; but suppose you just use a chunk of RAM as a swap device
[http://kerneltrap.org/node/3660]. Similarly, /tmp is mounted as a ramfs.
Given such a setup, is there any reason to fear data leakage to sectors
outside the encrypted partition?
Thanks for any hints,
Marvin
