Drone Security Fundamentals

Basics

Unmanned Aerial Vehicles (UAVs) combine embedded systems, RF communications, and sensor technology - each presenting unique attack surfaces.

Drone Architecture

Flight Controller

  • • Core processing (Pixhawk, DJI)
  • • IMU sensor fusion
  • • Flight mode logic
  • • Failsafe handlers

Communication

  • • RC link (2.4 GHz typical)
  • • Telemetry (433/915 MHz)
  • • Video downlink (5.8 GHz)
  • • WiFi/Cellular (some models)

Navigation

  • • GPS/GLONASS receiver
  • • Compass/Magnetometer
  • • Barometer (altitude)
  • • Optical flow (some)

Payload

  • • Camera/Gimbal
  • • Sensors (thermal, multispectral)
  • • Delivery mechanisms
  • • Custom payloads
