There is nothing inherently more risky in handling "inbound" connections vs. "outbound" connections. Either you are doing stupid things with untrusted data (i.e., anything not from your own trusted systems) or you aren't. How the data comes into your system is completely irrelevant. If you have too little clue to know how to build a secure listener, chances are you shouldn't be building a poller either.
