Re: Windows Server 2003 - Not secure from my test but OSX from Mac is secure from the start

I agree.

It seems to me that if you boot up a linux CD or even a floppy, no OS is safe 
at that point, unless the file system is encrypted -- but by the same token, 
someone could just dowse the thing in kerosene and light it on fire.  What we 
are really talking about here sounds more like physical security.  

If you value it, lock it up.

It can be argued very effectively that no machine is "safe" unless it is

problem in general.  With a SUN machine, it is easy to boot from a CD
and reset the Root password.  If I remove the CD drive, it is not
difficult to add a new CD drive.

There are so many tools out there that can reset the Administrator
account with console access to Windows that _no_ Windows machine is
safe if it is not physically secure.

</SNIP>

A prime example of this can be observed by booting a Windows XP
machine off a Windows 2000 CD.  Windows 2000 "assumes" that the SAM
is corrupt and allows you to fire up the recovery console to pull off
just about anything you want including stuff off the encrypted
partitions.

Another example of this are the Linux boot floppy utilities that
actually 1-  reset the Admin password to the one of your choice  2-
allow you to select one or 3 - allow you to dissect and decrypt the
SAM. This is why so many of the remote management "disk-less floppy"
utilities make me nervous.  Now I can use "password recovery"
utilities over the wire.

Just what I needed - SOMETHING ELSE to worry about......

Thanks,

Jimi
