Please help me with internet connection sharing

[morrisman1]

I want to share my connection over ethernet, but it is critical that it is passworded as its a large semi-public network and I dont want anyone else using my internet.

System preferences makes it easy to do this over wireless but it gives no password options for over ethernet.

help is much appreciated!
