    This thesis conducts a comprehensive analysis of security in an IoT environment using LoRa and LoRaWAN technology, applied to a real system consisting of IoT nodes, a LoRaWAN gateway, and a backend infrastructure developed with ChirpStack. The analysis seeks to detect vulnerabilities related to cryptographic management, access control, wireless communication, and interface exposure, taking into account the threats inherent in LPWAN networks and the guidelines established by OWASP IoT Top 10. The methodology used consists of four stages: designing and implementing a controlled test environment, which includes setting up a LoRaWAN server on a Linux virtual machine, integrating nodes, and configuring an operational gateway; conducting communication tests, validating RF parameters, and functionally analyzing the IoT system; employing methods to evaluate security using techniques such as sniffing, replay, interference, and passive analysis with Flipper Zero and SDR equipment; classifying the risk and devising measures to mitigate it based on telecommunications standards and engineering best practices. The findings show that there are serious vulnerabilities in unencrypted LoRa links, that LoRaWAN metadata is exposed, that there are fingerprinting risks, weaknesses in key management, and susceptibility to RF attacks such as replay and jamming. Based on these findings, a technical mitigation guide is developed with the aim of strengthening the confidentiality, integrity, and availability of the IoT system. To this end, suggestions are made regarding encryption, authentication, physical control, firmware hardening, and spectrum monitoring. This study helps to understand and strengthen security in Internet of Things solutions based on LPWAN technologies.
