No way at all to avoid security. Even if the transit area is open, this only avoids going through passport control. The rest is the same. You will be made to wait until several security guards arrive and do the whole questioning business. In a way it is worse, because (i) you have to wait for them to make their way to the transit area and (ii) there is only you there and they have all the time in the world to question you and search you.

It's not that I would advise against it, just be prepared. But don't do it if you have luggage checked through, or if you have dodgy stamps in your passport which you can't explain without looking too shifty. Seriously though it's fine.
