Both descriptions are justifiable. Poorly protected IoT devices have been used in numerous Distributed Denial of Service DDoS attacks and supposedly helpful and friendly devices have invaded the privacy and exposed the personal information of their users.
What I am concerned about is that they are not paying enough attention to what the traditional computing industry has discovered the hard way. Once the easy and obvious security flaws have been corrected, the evil doers will move on to other attack surfaces.
These other vulnerabilities that computer makers have had to deal with will undoubtedly be the next target of IoT hackers. And most important, what to do about them. Many in the IoT ecosystem seem to consider their devices as simple, single use, throwaway devices, such as a basic appliance or embedded system that you ship and forget. This perception is problematic, as more and more IoT devices continue to be developed.
Such attack vectors are not a new phenomenon. Network connected computer systems have been dealing with them since the advent of the internet. The problem has been that the developers of IoT devices have seen their gadgets as simple, single purpose devices that are not susceptible to nefarious acts, and therefore, not easily attackable. Well, it turns out the opposite is true. Since the early days of computing, platform firmware has been created to initialize the system hardware and load the initial software.
For traditional computing platforms, this software was typically an operating system loaded from a disk, but even on embedded platforms without a traditional operating system, software is typically loaded from a slow non-volatile storage into faster RAM memory for normal operations. While simple embedded and SoC systems moved to monolithic solutions like U-Boot and coreboot, most larger and general-purpose systems looked to the UEFI standard. Ultimately, attackers can then disable protections provided in the software after boot-up and load whatever other programs they so choose.
How to Manage Software Updates on Internet of Things (IoT)?
Additionally, they can modify normal software to do their bidding before it has even been started. If the bad guys can get control of the system early enough, that system can be compromised entirely. The same is true if the code update process is compromised.
If a hacker creates their own code and swaps it with the code originally provided by the system manufacturer, then all the bad things listed above can also be accomplished in a system with a compromised system update.
The UEFI specification provides standard interface descriptions and an architecture designed to significantly limit such threats. The two primary technologies used to secure a system from these threats are:. UEFI is the only firmware solution that includes these security features as part of its industry standard. Also, while many security researchers and hackers have been testing its design, no one has been able to find any flaws in the security architecture.
A few implementations have been flawed, but not the design. There are many more security related capabilities provided by UEFI, but they are beyond the scope of this article. I believe there are a couple of major reasons:. How do you get started? Downloading the latest UEFI Specification and trying to read it cover to cover it is probably not the best way to start. First, UEFI is an interface specification, not an implementation.It combines more than 10 years of firmware vulnerability research and experience from an uncountable amount of vulnerability scans.

IoT is the next big technology that will change the way we communicate and exchange data.
Every day thousands of IoT devices are coming into the market. Most of these devices collect and exchange data over the cloud. Not much effort has been put into securing the IoT devices, thus understanding the security of IoT devices and their communication is of utmost importance.
If one has a close look at any IoT Network, there are many components to be secured. Some of them are listed below —. Security of all the components mentioned above cannot be covered in a single post.
In this post, I will explain how to analyze the firmware of any IoT device since not much resource is available on firmware security. Firmware is a software program programmed on a hardware device. It provides the necessary instructions on how the device communicates with the other computer hardware.
Have you seen something like shown in the image below? Put simply, the software running on any IoT device is termed as Firmware.
Firmware Analysis Methodology — To analyze any firmware, there are two ways to do so — one is manual and other uses a tool. Manual Analysis consumes a lot of time, and due to time constraints often it is not possible to do a manual analysis. Thus, automated analysis of firmware comes in handy.
In this post, we will learn how to use a tool named Firmwalker for analyzing the firmware. Please download it for performing firmware analysis practically. Above are the issues widely found in IoT firmware and the tool does a great job in identifying the issues. There are four firmware files available. Download the one belonging to the year After downloading, copy the file into Firmwalker folder as shown below I have renamed the file as DLink.You may need to update the firmware on the devices connected to your IoT hub.
For example, you might want to add new features to the firmware or apply security patches. In many IoT scenarios, it's impractical to physically visit and then manually apply firmware updates to your devices. IoT Hub automatic device management uses configuration to update a set of device twin desired properties on all your devices. The desired properties specify the details of the firmware update that's required. IoT DevKit is an all-in-one Arduino compatible board with rich peripherals and sensors.
And it comes with a growing projects catalog to guide you prototype Internet of Things IoT solutions that take advantage of Microsoft Azure services. Finish the Getting Started Guide to:. An active Azure subscription. If you do not have one, you can register via one of these two methods:. A new VS Code window with a project folder in it opens. Notice: for real product we highly recommend you to use the Azure IoT Hub Device Provisioning Service which can allowing you to provision millions of devices in a secure and scalable manner.
And here is the tutorial which can help you to learn how to use Azure IoT Hub Device Provisioning Service auto-provisioning a real device. This sets the connection string that is retrieved from the Provision Azure services step.
The initial version of the device firmware is 1. VS Code then compile the code and generate the. Follow this tutorial to create a new Storage Account, or skip this step if you want to use a existing one. Navigate to your new storage account in the Azure portal, scroll to the Blob Service section, then select Blobs. Create a public container for storing firmware files. This section specifies the target content to be set in targeted device twins. There are two inputs for each set of settings.
The first is the device twin path, which is the path to the JSON section within the twin desired properties that will be set. The second is the JSON content to be inserted in that section. The Settings may like this:.
Metrics provide summary counts of the various states that a device may report back as a result of applying configuration content. For example, you may create a metric for pending settings changes, a metric for errors, and a metric for successful settings changes.
Use the tags property from your device twins to target the specific devices that should receive this configuration. You can also target devices by device twin reported properties. Since multiple configurations may target the same device, you should give each configuration a priority number.
If there's ever a conflict, the configuration with the highest priority wins. Enter a positive integer for the configuration Priority. Highest numerical value is considered the highest priority.If you have IoT devices in your home, the truly frightening thing is that your devices might have already been attacked and compromised. And you might not even know. How many?
More than three years ago, experts predicted that by there would be over 20 billion IoT devices in use. But according to this more recent McAfee study that number is projected to be 25 billion by It seems that our predictions of the number of IoT devices are always low, as IoT device adoption is driven by many factors like price and ever-increasing network communication speeds. And according to Nokia, 5G communication is likely to speed IoT device adoption. So what kinds of vulnerabilities are we talking about?
According to the OWASP IoT project all IoT devices have potential security vulnerabilities like weak passwords and other poor default security settings, lack of encryption when devices communicate over the network, and poor or non-existent user-serviceable device management.
At the heart of an IoT device are the key characteristics of the underlying hardware that make IoT devices work:. Essentially, IoT devices contain sensorsactuatorsor both. Sensors acquire data, and actuators control the data or act on the data. All IoT devices have a way to process sensor data, store that data locally if necessaryand provide the computing power that makes the device operate.
If data from multiple sensors needs to be coordinated, or if data needs to be stored in flash memory for whatever reasonit is the data processing component of the IoT device that does it. The firmware that runs an IoT device is the onboard software that sits between the hardware and the outside world, and generally falls into one of two categories: embedded firmware or operating system-based OS-based firmware.
IoT devices are resource-constrained, so they often use custom-built, embedded firmware, which is another term for the software that runs on the device.
In many cases, the only cost-effective solution for device manufacturers is to engage programmers with a deep understanding of the hardware to write embedded software firmware to interact with the hardware. Embedded software engineers have to perform double-duty. An IoT device now probably runs an operating system OS that provides an abstraction layer between the hardware and other software that runs on the device. A popular OS choice for many device manufacturers is Busyboxa stripped down version of the Unix operating system that contains many of the most common utilities, has a very small footprint, and provides many capabilities of Unix in a single executable.
IoT devices most often communicate wirelessly, which means they can be anywhere in your home or enterprise. The communication needs of the device change depending on how the device is designed to work. Some devices are designed to work by making a direct From there, the device can access the internet. A motion-activated security camera is a popular example of this type of device, which uses wifi to send its data to a cloud server, for example, which you can access via an app on your smartphone.
Some devices are meant to work as part of a group of IoT devices. In the simplest scenario, you press the WPS button on your IoT device, then press the WPS button on the router, and the two devices are eventually connected. Other devices create a Wifi access point you connect to using an app on your smart phone where you to enter your wifi network credentials, which will be used later by the IoT device to connect to your wifi network.
Still other devices, like hubs and gateways, scan and add devices that it detects are in your home or business.IoT Inspector is a platform for automated security analysis of IoT firmware. Simply upload the firmware, start the analysis and a few minutes later the results will be available. Vulnerabilities in IoT devices are constantly exploited by attackers to access confidential corporate data, steal user information or inject dormant malware.
IoT Inspector is the necessary tool to analyze firmware of a product against potential threats. IoT Inspector helps us significantly in the development and operation of customer devices.
