IETF draft-irtf-t2trg-iot-seccons: State-of-the-Art and Challenges for the IoT Security

State-of-the-Art and Challenges for the Internet of Things Security

The Internet of Things (IoT) concept refers to the usage of standard Internet protocols to allow for human-to-thing and thing-to-thing communication. The security needs for IoT systems are well-recognized and many standardization steps to provide security have been taken, for example, the specification of Constrained Application Protocol (CoAP) secured with Datagram Transport Layer Security (DTLS). However, security challenges still exist, not only because there are some use cases that lack a suitable solution, but also because many IoT devices and systems have been designed and deployed with very limited security capabilities. In this document, we first discuss the various stages in the lifecycle of a thing. Next, we document the security threats to a thing and the challenges that one might face to protect against these threats. Lastly, we discuss the next steps needed to facilitate the deployment of secure IoT systems. This document can be used by IoT standards specifications as a reference for details about security considerations applying to the specified protocol.



US-CERT ST17-001: Securing the IoT

Security Tip (ST17-001):  Securing the Internet of Things
The Internet of Things is becoming an important part of everyday life. Being aware of the associated risks is a key part of keeping your information and devices secure. The Internet of Things refers to any object or device that sends and receives data automatically through the Internet. This rapidly expanding set of “things” includes tags (also known as labels or chips that automatically track objects), sensors, and devices that interact with people and share information machine to machine.[…]



Attify’s Firmware Analysis Toolkit and AttifyOS VM

Attify has a Firmware Analysis Toolkit (FAT). Apparently they include a pre-built version of it in their AttifyOS VM, and use it in their IoT training:

Firmware Analysis Toolkit: FAT is a toolkit built in order to help security researchers analyze and identify vulnerabilities in IoT and embedded device firmware. This is built in order to use for the “Offensive IoT Exploitation” training conducted by Attify. As of now, it is simply a script to automate Firmadyne which is a tool used for firmware emulation. In case of any issues with the actual emulation, please post your issues in the firmadyne issues.

Attify OS – Distro for pentesting IoT devices: Instead of spending time installing, configuring and setting up various tools required for IoT pentesting, here is a pre-made distro for you containing the tools that would come handy during any Internet of Things Security Assessment or Penetration testing.

From training site:
Firmware analysis: IoT devices and embedded systems run on firmware, which often hold a lot of secrets and sensitive information. This module will help you analyze and extract firmware, thus helping you identify vulnerabilities in the firmware for IoT devices. We will also look at firmware emulation using FAT, a custom tool built by Attify with which you can emulate firmware and perform all sorts of “non-hardware” based attacks. The tool is fully scriptable and hence can be modified and used according to your preference. You also get access to the API, which will allow you to use the tool for your own further research.

NXP: designing IoT devices with secure boot

NXP has a webinar for IoT makers, talking about secure booting. ‘Webinar’ scared me, but there’s no registration required. 🙂

Watch this on-demand presentation to learn how to:
* Manage the life cycle of an IoT edge node from development to deployment.
* Leverage hardware and software offerings available with the Kinetis MCU portfolio that can help you protect against attacks.
* Ease the burden of secure IoT edge node development using new processors and architectures from ARM.

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:
