"Custom" rules I didn't create??

Sorry if this has been asked and answered before.  I am new to NIS and today, for the first time, looked at my logs.  I noticed many instances where rules have been created for the firewall for certain programs.  I understand how rules are created automatically, but there are lots of rules that are supposedly "custom" and that it says I have created.  Is this just poorly worded?  Or is it possible someone or something malicious has been messing with my firewall?  This is a brand new laptop, but it is on a wireless network--secured, but wireless.

 

Thank you!!
