Anomaly Detection in IoT Networks
Halaj, Jozef ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
The goal of the thesis was an analysis of IoT communication protocols, their vulnerabilities and the creation of a suitable anomaly detector. It must be possible to run the detector on routers with the OpenWRT system. To create the final solution, it was necessary to analyze the communication protocols BLE and Z-Wave with a focus on their security and vulnerabilities. Furthermore, it was necessary to analyze the possibilities of anomaly detection, design and implement the detection system. The result is a modular detection system based on the NEMEA framework. The detection system is able to detect re-pairing of BLE devices representing a potential pairing attack. The system allows interception of Z-Wave communication using SDR, detection of Z-Wave network scanning and several attacks on network routing. The system extends the existing detector over IoT statistical data with more detailed statistics with a broader view of the network. The original solution had only Z-Wave statistics with a limited view of the network obtained from the Z-Wave controller. The modular solution of the system provides deployment flexibility and easy system scalability. The functionality of the solution was verified by experiments and a set of automated tests. The system was also successfully tested on a router with OpenWRT and in the real world enviroment. The results of the thesis were used within the SIoT project.
Secure Gateway for Wireless IoT Protocols
Hošala, Martin ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
Táto práca bola zameraná na vytvorenie funkčného prototypu zabezpečenej brány pre bezdrôtové IoT protokoly s využítím BeeeOn IoT Gateway. Na vytvorenie výsledného riešenia bolo potrebné analyzovať existujúce zabezpečovacie systémy IoT, navrhnúť ich integráciu s BeeeOn Gateway a systém nasadiť. Ako zabezpečovacie systémy v tejto práci boli použité moduly NEMEA vyvinuté v rámci projektu SIoT. Výsledné riešenie beží na routeri Turris Omnia a pozostáva z BeeeOn Gateway, piatich detekčných modulov SIoT a ďalších modulov NEMEA potrebných pre plnú funkčnosť detektorov. Potenciálne hrozby sa zisťujú v sieťach Z-Wave, BLE a LoRaWAN. Používateľ môže so systémom interagovať prostredníctvom webového rozhrania systému Coliot, ktorý je tiež súčasťou výsledného riešenia a slúži na ukladanie a prezentáciu výsledkov detekcie. Funkčnosť systému bola overená experimentálne a množinou integračných testov. Testovanie odhalilo mnoho nedostatkov spojených s použitými podsystémami a väčšina z nich bola opravená. Výsledný systém sa používa sa v rámci projektu SIoT.
