There are both multiple methods for guidance of drones(GPS, terrain comparison, optical , other) as well as defeat of drones(GPS jamming/spoofing, RF spectrum jamming/spoofing, kinetic options.

The last 3 years has seen a wide range of counter-drone solutions developed. Some are absolute rubbish, others are quite solid.

For exceptionally high value targets a layered defence would be a recommended and likely option.

18 months ago Syrian rebels attacked a Russian base with a drone swarm with mixed results.

This seems more like a drone version of Mumbai 2008, exhibiting early signs of professional planning, command, control, and execution.
