MAIOS: A Multi Accountability IoT Oriented Switch

Titled MAIOS (Multi Accountability IoT Oriented Switch), this article presents an SDN (Software Defined Networking) switch architecture, which provides specific network segregation for IoT devices, increasing their protection against cyber threats. MAIOS improves security aspects through a logical interface with a control plane, which efficiently manages threats to IoT devices, including the implementation of dynamic security policies. The control plane application layer can contain high-level security management modules based on AI and data analysis techniques, which can be applied to the data plane through MAIOS.Considering that aiming for ease of installation and use, IoT devices are designed with shallow security, to say the least, and this creates a scenario ripe for attacks. It is important to emphasize that even for industrial environments and embedded systems, many security problems have been reported.MAIOS was designed considering functional and nonfunctional requirements of deployment scenarios, whether in industrial, campus or domestic environments. Aiming at usability, an interface was developed so that users can configure and monitor IoT devices. However, this interface was developed for proof of concept and we understand that in a real application scenario, MAIOS will be integrated into an appropriate management environment.The effectiveness of MAIOS was evaluated through security and performance experiments in simulated environments, based on widely used datasets, demonstrating its ability to identify and mitigate cyber threats, providing robust security for IoT devices.
