Are that many people really that careless with their laptops? I think people worry too much about
encrypting laptops. If a company has it's shit together they are not letting you go home with
sensitive info(They should be preventing cd burning and removable media,disabling such actions
,even not having such devices installed, no usb ports on PC's, physical locks on PC case,no
offline files, etc...), all data should be backed up to a network location that has strict
security. A well thought out security scheme considers this and more. If you are among the few
that are allowed to do so (a handful maybe?) then hopefully you are not so irresponsible as to
leave it unsecured (by which i mean out of your sight) If someone targets you because of your job
then its probably fair to say that you deal with sensitive info, so they will( by which i mean i
would) be counting on encryption and be prepared to deal with it. Most of the high profile stories
i have seen involve employees taking home info they should not have in the first place. Again the
organization's IT Dept. should be disabling cd burning and removable media to reduce the incidence
of such cases.Prevent the copying of files off the local volume or network location. Considering
average "real world" user skill levels that would probably prevent most such incidents.
