Análisis de seguridad en redes LPWAN para dispositivos IOT

Abstract

This document shows the analysis carried out on the security of LPWAN technologies, focusing the study on the vulnerabilities present in Sigfox technology. The methodology used is based on the test development guide presented by OWASP, which consists basically of identifying vulnerabilities and testing recommendations to validate them. In addition to the use of the methodology, documentary research on vulnerabilities in similar LPWAN technologies was carried out. Practical tests were developed based on industry recommendations for the safe use of IoT, these were performed in a basic Sigfox communication test environment using the Xkit RCZ4 card, resulting in vulnerabilities in physical devices, in their design and in the Sigfox backend. A comparison was made with LPWAN technologies in the market and it was analyzed if Sigfox is really the safest network in the field of IoT as it is sold in the market.
