Starting June 2015 they will be switching to to centralised security.
Centralised security for transfer passengers will be conducted via a seperate route. There will be extra floors on Top of Pier E, F and G for additional seperate routes to keep the passengers who have been screened seperate from those who still have to go through security.
At the entrance of the piers connected area's will be set up with security checks (one at E, one at F and one for the G-H-M gates). If passengers have undergone the same level of security checks on their departing airport then no additional security checks are needed.

For departure passengers it means one checked passenger area for gates D-M (non-Schengen) and one for gates B-C (Schengen). I believe three security checkpoints will be setup in the departure halls..
