How does Zonealarm check outgoing packets?

How does Zonealarm for Windows check outgoing packets to ask if you
want to allow a specific _program_ to access the web?

How does it warn that a program is asking for server rights?

I'd like to see if these features could be incorporated into a
unix/linux netfilter firewall but first want to understand how it's
done.

I'm hoping that some on the list have an idea of how the internals
work.
