 freebsd security..
just recently installed BSD4.2 and was just wondering...supposedly Unix
is one of the most secure OS(so i heard), yet a person can gain access
to root by just booting in single user mode using the "boot -s" command
and bypassing the passwd for root to get at any file contained
therein...anyone want to clarify this perception or am i missing
something or not installing the correct security feature? appreciate any

If the person trying to get your data has physical access, there is very
little way to stop them from, eventually, getting your data. It is secure
in the sense that short of physical access, there are very few ways to
break in.

You can stop boot -s working if you edit /etc/ttys appropriately.
Look at man boot and man ttys for more details.

I believe that if you change /etc/ttys to list "console" as "insecure"
rather than "secure", it will prompt for the root password before
starting the single-user shell.  I've never actually tried it.

Asking for the password in single-user mode won't slow the intruder down
very much.  If they can type "boot -s" they can stick a floppy in the
slot first before they type it.
