title: IM Port Protection
body: <p>Greetings,</p>
  
  <p>I've been thinking about, just for fun, creating a Instant Message type of program using IRC.
  I've found some information on the IRC sdk and such but I was wondering.</p>
  
  <p>In what way is, using IRC protocols to connect to a random server, save concerning hackers entering your computer via ports used by IRC? </p>
  
  <p>If there actually is a possible way for hackers to enter your computer using ports.. is there any way to programmaticly protect your projcet against this?</p>
