I have no metrics myself against which to measure this. I have
Googled, but
have found it difficult to distinguish the FUD and biased/inaccurate
information from the "real" - and reliable - information. I would be
glad of
some opinions from the list.
If I set up a computer to dual boot Windows and Linux (specifically
Debian
Lenny) does the fact that Windows is sharing the computer in any way
jeopardise the security of the Linux installation?
In the very least, a Windows rootkit or virus could potentially mess up
your partition table, or the master boot record; but there are
certainly other equally risky scenarious that other list memebers will
most certainly come up with. So the answer to your question is
definitely "yes".
Does it make any difference whether they are in separate partitions
on the
same disk or on separate HDDs?
For the above scenario, hardly.
Would running Windows in a VM from Linux make the Linux host less
secure than
dual booting, or more so?
Depends on the virtual technology used. Depends on how well is the
particular virtual environment isolated from your host OS and the "bare
metal" on which it is running. In this regard, I'd say that XEN is not
equal to kvm (which uses a kernel driver), and kvm is, in turn, not
equal to qemu (which runs entirely in userspace, IIRC).
Would the Linux host in fact be more/less/equally
secure than/as it would be if Windows were not on the box at all?
Is this meant as a joke or as a genuine question?
;P
