DRONE CYBER DEFENSE
🛡️ DRONE CYBER DEFENSE Practical & Technical Countermeasures 1. 🔐 CORE PRINCIPLE 👉 Drones = Cyber-Physical Systems This means they must be secured across three critical layers: 1. Communications (Link) 2. Platform (Drone hardware/software) 3. Control (GCS + operator) If one layer fails → the entire system is compromised. 2. 📡 SECURING COMMUNICATIONS (ANTI-HIJACK) 🔴 Threats: Signal hijacking Data interception ✅ Countermeasures: 1. End-to-End Encryption AES-256 or military-grade encryption VPN over data link (if IP-based) 👉 Without encryption, drones can be compromised within minutes. 2. Frequency Hopping (FHSS) Constantly changes transmission frequency Reduces risk of interception and jamming 3. Authentication & Key Rotation Secure handshake between drone and GCS Session-based key rotation 4. Anti-Spoofing GPS Multi-constellation: GPS + GLONASS + Galileo Inertial Navigation System (INS) backup Signal anomaly detection 3. 🧠 SECURING THE DRONE (ONBOARD SYSTEMS) 🔴 Threats: ...
