How do I view the list of trusted applications?

How on earth do I see the list of trusted applications?
 
The only thing I can kind find that is kind of close is "utilities -> system control -> control active processes"
but that only shows you apps for already running apps.   
 
I want to reset the allowed access list.   I turned the firewall on and steam.exe is already allowed, along with who knows what else.
