ARM IETF ID on IoT firmware update architecture

IETF Internet draft: draft-moran-fud-architecture-00:

A Firmware Update Architecture for Internet of Things Devices
July 18, 2017

Vulnerabilities with IoT devices have raised the need for a solid and secure firmware update mechanism that is also suitable for constrained devices. Incorporating such update mechanism to fix vulnerabilities, to update configuration settings as well as adding new functionality is recommended by security experts. This document specifies requires and an architecture for a firmware update mechanism aimed for Internet of Things (IoT) devices. The architecture is agnostic to the transport of the firmware images and associated meta-data. This version of the document assumes asymmetric cryptography and a public key infrastructure. Future versions may also describe a symmetric key approach for very constrained devices.

There’s a mailing list for FUD:

UEFI-based IoT firmware updates

Simplify Secure, UEFI-Based IoT Firmware Updates
Rich Nass

In the age of the Internet of Things (IoT), where everything is becoming connected, each connection point can be viewed as a “Hack This” sign for the bad guys. To prevent this, developers need to be sure that all firmware and associated patches are kept up to date with verified and secure revision control. Any unpatched or outdated firmware can allow access to critical system functions. Unfortunately, this need to keep firmware updated often goes overlooked by the development team after a product has shipped. In many cases this is due to the resources required and complexities involved. But what if the whole process of updating and securing firmware remotely or over the air (OTA) could be standardized and encapsulated within an easy-to-use, reliable solution that works seamlessly with your underlying hardware? It turns out that such a solution is already in hand.[…]

IoT security, AR, and VR

[…]On the subject of supply and demand leading to security issues, Ben Smith, CEO of Laduma, stated, “As new developments are rushed to market in order to gain a lead on competitors, there is a risk that mistakes are being made.” Because of the massive popularity that Virtual and Augmented Reality has gained in the last few years, companies were forced to either put out products that were not necessarily secure or forego their inclusion in the massive VR market of 2016. However, it is no surprise that the connection of multiple insecure devices on a network creates a perfect entry for hackers to retrieve the massive amounts of data which Virtual Reality platforms both receive from the users themselves as well as collect without necessary consent for marketing purposes. In fact, Tata Communication’s Srinivasan CR once stated on the subject, “Every device connecting into a network is a potential vulnerability which can be used to infiltrate the network itself and other devices connected to it.”[…]

Mozilla Corporation abandons IoT project

As expected, Mozilla has canceled their IoT project:

“This experiment has concluded.”

No press on the Mozilla press site in months, however:

OWASP IoT firmware guidance

I just noticed that the OWASP project, the Open source Web App Security Project, has an IoT project, and that project has a Firmware Analysis Project

“The Firmware Analysis Project is intended to provide security testing guidance for the IoT Attack Surface ‘Device Firmware'”.

Nothing specific to UEFI, coreboot, ACPI, SMM, etc. They are using the embedded OS definition of firmware.
