This is normal. It is possible to add a password requirement in
single user mode but, since single user requires console access, it
would be pretty useless. In my experience, the most common use for
single user is to reset a root password so the lack of a password is a
compromise. In any case, no system is secure if the console can be
accessed. Period. Anyone who knows enough to boot to single would
probably know enough to make a set of boot disks and completely bypass
your boot files anyway.
Linux is secure but it is not magic. Security is a never ending
Darwinian process and anyone who cannot get used to that fact of life
and better pull his netowrk cable now.
