Will I need to go through security again if I have a layover in Barcelona?

I'm an American citizen and I'll be flying on one ticket/same airline from Naples, Italy to Copenhagen with a one hour layover in Barcelona. The connecting flight will be in the same terminal, but will I be able to just go to the gate of the next flight? Or do I have to go back through security? I only have a backpack so I won't be dealing with checked luggage.

As you originate in a Schengen country and connect in a Schengen country, flying to another Schengen country, these should be treated as domestic flights and you should not have to go through security, as long as your flights arrive at and depart from the same terminal in Barcelona.
