Drones need a GPS module that also reports prohibited airspace. Drones could use that to shut down if someone tried to fly them into prohibited airspace.
Unfortunately (maybe), drones aren't magical technology that you can only get from the government.
The cat is out of the bag, it's easy to make a drone at home out of generic parts. Anyone who wants to fly a drone into prohibited airspace can do it. And an even remotely-sophisticated attacker could do it with almost no chance of getting caught. That's just the world we live in now.

Anti-drone technology is advancing. Chengdu airport installed what looks like a fire-finder radar, usually used to track artillery shells. Avaelliant has a drone detection system for sale, and it's in use at a few airports. Both are phased array radars, with no moving parts and flat antenna panels. Avaelliant's unit looks like a big cell phone tower antenna.
