I was amazed that in the left-hand panel of FINDER, under the SHARED tab, there are about 6 other computers that I am seeing. I am concerned that others may be able to access my computer via my wireless connection. How can I make sure I am protected, and my computer is invisible to them?
Got a tip for us?

Without credentials on your computer, the only thing that a spectator can do to your computer is read its name in the Sidebar. They cannot open, read, or edit any files on the computer. If you share your drive, then they have essentially drop-box privileges. It is a non-trivial matter to allow a remote user to gain access to your Mac.
in the sharing prefs disable everything
The main ones someone could use to access your computer is file sharing, windows sharing, screen sharing, remote login (ssh) and remote desktop.
To do any of this they would need to have a user account setup on your mac, the only real way of doing anything malicious i can think of is remote login with ssh, but if remotre login is off i think that turns ssh of.
As said by modernape if you enable stealth mode under security>firewall>advanced, that will stop your computer responding to pings and portscans etc.
