Yes, you would have to go through a security check since you come from a non-schengen country.
55 minutes might be too little time if the control takes more time than expected but it should be enough since you don't have to check in anything.

I have been told by a travel agent: If an airline sold you a ticket with a short connection, the airline thinks it's long enough. If you miss the connection it is the airline's problem β they would have to get you on the next available flight. This is of course assuming both flights are part of the same booking.
