The talk is directed at Bitlocker, the full disk encryption in Windows Vista, but it applies to all similar methodologies.
It’s simple. Fools don’t have physically secure, unencrypted backups. Fools think everything should run like lightning, regardless of the strain on the system. And, of course, fools lose passwords.
Doesn’t sound foolproof.
Might I suggest using virtual disk encryption, like that offered by PGP. It is slightly more cumbersome but puts less strain on the system and the “product” is portable – better design for fools (like me).
