EU foreign affairs and security chief Catherine Ashton has urged nations to work together on cyber defence in a new report.
The document says that governments should develop co-operative projects to tackle problems relating to technological attacks and the use of drones.
Ashton said that drones would see an increase in use both within the military and for border control and agricultural projects.
According to officials, the EU could set out rules for using drones in civilian airspace and fund the development of technology that could be used in future models.
The report, which was commissioned in the build-up to an EU summit in December, also called for development of a new satellite communications system.
The advice could lead to greater co-operation between nations on cyber defences.
