I have opened port 80 to traffic for some web page development I'm doing (using port forwarding in my router). I realize this opens up my computer to intruders. What's the best way to prevent intruders from coming in through port 80 while it's open? I'm working on a Mac.
Is there a Mac firewall setting or program that will detect and notify me of traffic (either unexpected traffic or all traffic) on this port? What I imagine is a dialog box would pop up for every access attempt, and I would have to approve it before it comes in.
