Hello all,

Utimaco (www.utimaco.com) has a produkt called SafeGuard Easy (for win 2k).
It provides total harddrive encryption (including the filesystem) and
pre-boot authentififcation.
Basically it protects your laptop.

The documentation states:

"Unauthorized persons have no access to the system, since the pre-boot
authentication (PBA) asks the user for authentication before booting the
operating system. This kind of authentication cannot be manipulated PBA
therefore guarantees maximum security. Neither keys nor passwords are stored
on the PC's hard disk. All the information that is required to boot the
operating system is derived from the password. This makes the use of hard
disk tools for analyzing the hard disk completely ineffective." 

and furthermore:

"Finally, a secure challenge/ response procedure is available to re-issue
the password, if a PC has been blocked because the pass-word has been
entered incorrectly or forgotten."


My question is, would it technically be possible to provide a means to
authenticate a user before booting the OS without the use of special
hardware, and not store any password on the disk? And if so, wouldn't
booting from a floppy bypass that?

It sounds like they encrypted the startup environment and the password is
the key to decrypt it, but that sounds very fairy-like...
But if so, how can they provide 'a secure challenge/ response procedure' to
restore the password?

Is this security through obscurity? or is it just to elite for me to grasp?

Thanks for your comments

Joost

If you use the Timeserv.exe from the NT resource kit, you will want to check
this link from the M$ support site:

n&FR=0&qry=timeserv&rnk=6&src=DHCS_MSPSS_gn_SRCH&SPR=MSALL

We use the timeserv.exe in maintaining the time synchronization of our
network and the when setting it up according to the documentation, our
domain servers hit 100% CPU utilization.  The above page has a link to the
updated timeserv.exe file.

Just thought I'd pass this along.
