FreeBSD root passwod reset single user mode

If I forget the root password on FreeBSD, I can put in the install CD/USB into the computer and then boot into single user mode, then reset the root password (without having to know the old) by typing `passwd'

This is convenient but isn't it also a massive security hole? If someone has physical access to a computer running FreeBSD does that mean they can just hijack the root account this way
Is there a way to disable this?

If they have physical access, they can do anything to it, including steal all your data.

The thing is, how many, of your friends/family/enemies know how to do that.

You should be able to disable access to all external media, (check their handbook to see how).

This is why server rooms have multiple levels of physical security...card swipes to get in, cameras, etc. Any OS has this vulnerability: pull a windows server drive and pop it in a Linux or BSD machine and you can read all the data.Or boot a windows machine with a Linux live thumbdrive and you can read all the data...
