Does anyone know of good solutions for encrypting data at rest on
Macs (preferably the entire drive)? Unlike my last job, "throw the
drive in a GSA Class 5 safe when you leave the room" is not an option
for me at the moment.
I've experimented with FileVault, but have heard several horror
stories of losing data if the machine crashes while you're logged in
as a user with a FileVault-protected home directory.
I've used PGPDisk in previous jobs, which works quite well as an
encrypted file repository (especially one that can be shared between
Macs and Windows boxes), but doesn't protect things like the web
browser cache, cookies, history, email cache, etc.
I've recently been experimenting with Cryptocard's Crypto-Logon,
which is quite cool, but is only an authentication mechanism, not an
INFOSEC mechanism.
I've looked at firewire hard drive enclosures that encrypt the data
in flight and use a crypto ignition key--these are closest to what I
want, but all of the ones I can find on the commercial market (based
on enova's X-Wall chip) use insecure tokens (i.e., ones that can be
easily duplicated or sniffed). However, these look the most
promising as long as you can keep physical control of the token.
I've seen fingerprint-protected drives, but I haven't found any
substantial security analyses of them, so I have no way to evaluate
them against my threat model.
Something that protected the internal drive of a laptop would be
ideal, but an external Firewire or USB drive would work. Ideally, I
am looking for something that requires a CIK or Smart Card *and* a
PIN/password (two factor authentication), and encrypts the entire
disk contents. Cost is not a major concern.
Does anyone know of anything on the market like this? It seems as
though it would be widely useful, but darned if I can find one.
Oh, and a side note to Apple people reading this: "encrypt whole
drive" would be a *really* nice feature to have in Leopard. If
you're looking for additional features ;-)...
