Hi Eminem,
With ZA it is very easy, you just have to look at the colors and know what these stand for, a green color is something that you have seen before, a purple is something is contacting out to the Big Bad Net,
other color means it is asking you for the first time - rethink your action there, second time it knows you clicked that option before and it turns green. Can be confusing when you cannot get the traffic lights apart, for the rest you can get accustomed to it, then you have the option allow and deny.
With programs and processes you know to be on your machine all is easy. Just memorize this scheme and you are rather secure,
