My personal experience has been that Dubai (which I believe is one on the list?) has some of the highest security I've seen. Everytime I go through it as a passenger connecting on another flight (not leaving the airport) I've been though security (shoes off x-rays e.t.c.) after leaving the plane and getting into the terminal proper. In addition there were spot checks in the waiting lounge before actually bording my onwards flight (on one trip, not all) where my belt was swabbed (presumably for explosives?) and I was asked to turn on my laptop to prove it worked. Never had that happen anywhere else.
