Assuming these are all DL flights, you should not have a problem making the connection. When you exit the plane, you'll walk down a hallway into a very fast moving security check. Even when it's backed up, it's rarely more than ten minutes until you are through. You'll go down an escalator and be within, at most, a five minute walk to your gate.

And remember, outside the US there is a little more leniency on holding flights for connecting passengers. The airlines are not judged on pushing the planes back from the gate like they are in the US. IME, in non-US airports, airlines are more inclined to wait five minutes for passengers they know are clearing the security check than having to put them up for the night and find room on a the single plane to that destination the next day, or pay to put them on a different airline. If your incoming plane is delayed an hour, you may have an issue.
