The increasing adoption of IoT devices using containers is revolutionizing the technology landscape, requiring advanced solutions for security and resource management. This thesis, conducted in the Drivesec company context, focuses on two central themes: secure container virtualization, user authorization and authentication in IoT environments on Amazon Web Services (AWS). The first part of the research presents a comparative analysis between two leading technologies for container creation and management, Docker and Podman. This analysis examines the performance and security of both technologies, exploring their capabilities in rootless and rootfull mode. The second part of the thesis explores user authentication and authorization in IoT environments using AWS capabilities.
