Qualche giorno fa Microsoft ha presentato il suo nuovo sistema operativo progettato per i dispositivi IoT: Azure Sphere OS. Il nuovo sistema operativo ha come obiettivo quello di fornire una piattaforma sicura-per-default per la costruzione di servizi IoT e superare i problemi che hanno reso i dispositivi IoT così sensibili anche ad attacchi di tipo non sofisticato tanto da consentire ad organizzazioni malevole la creazione di botnet o al possibilità di compromettere la privacy degli utenti.

Azure Sphere è una soluzione più complessa che consente la creazione di una piattaforma per l’IoT ed include anche microcontroller personalizzati che [...]
