Is a single point of failure more or less secure than multiple points? That is the question IoT designers should make when considering ARM's new mbed OS, designed to rein in the fiasco which is the current state of security in the IoT market. On the one hand this OS will run on just about any device you could want, even if you prefer your device remain on MIPS, Linux or another OS and regardless of your back end provider. It will allow encrypted updates to be pushed out to devices software or firmware from a single source and the companies which use it will be charge on a pay per use scheme as opposed to a fixed cost.
On the sinister hand, this means that when someone manages to exploit an unforeseen vulnerability in mbed, the communications between ARM and the devices or the factory set private keys, they will be able to own every single mbed device out there. That is unfortunately merely a matter of time and so we wait to hear from ARM as to how they plan to partition the devices which use mbed and other measures they will develop to prevent a worse DDoS than the Dyn DNS attack last week. You can take a deeper look at mbed's structure as well as ARM's new Cortex-M33 and Cortex-M23 microcontrollers over at The Register.
"So ARM has come up with mbed Cloud, a software-as-a-service platform that securely communicates with firmware in devices to install fixes and feature updates. Product makers pay to remotely manage all their sold kit. Crucially, they pay for what they use – whether it's pushing updates, or connecting millions of units, and so on."
