Open Source Embedded Software Development and Security Blog
IT security has never been more of a hot button topic than it is today. Increasingly, the focus is on the security of the Internet of Things (IoT) and the embedded systems that support these devices.
And so far, the traditional enterprise security architectures and procedures are failing to protect these systems from being compromised. The evidence is trumpeted in the headlines documenting successful compromises, emerging breach patterns, and the exploding volume of vulnerability advisories.
Discovering and Fixing Vulnerabilities Quickly: Securing Embedded Open Source IoT Devices in the Wild
The web of Internet of Things (IoT) devices continues to grow each day. In fact, by the year 2020, Gartner predicts that 95% of new electronic product designs will contain IoT technology; Forbes expects at least 80 billion IoT devices to be available by 2025. But with such a vast number of devices in use across the world, how can you hope to find flaws and address vulnerability concerns in a timely manner within your own IoT products?
14,000+ CVEs were discovered in 2017. In April of 2018 the CVE list had surpassed 100,000 entries, and that number grows every day. So how do you protect your embedded devices and open source embedded systems in IoT and IIoT deployments from this endless onslaught of security threats?
Traditional IT security isn’t protecting embedded open source systems in IoT and IIoT deployments
Here at Timesys, we’ve been noticing some concerning trends when it comes to open source embedded software security and the rise of Internet of Things (ioT) and other intelligent devices. We’ve been hard at work developing a solution that can help ease your burden of carefully developing, monitoring, and maintaining security measures on your devices.
After Notification: The Next Steps
In a previous blog, we covered how Timesys handles security monitoring and notification of open source software vulnerabilities, how to generate reports on demand for the current state of a Yocto or Factory build on the desktop, and how to view, generate, and subscribe for reports on the web. If you missed it, now would be a good time to catch up before reading this post, because the next steps cover what to do …
Webinar Series: Reduce Risk with RISC – Designing and Maintaining Secure Embedded Linux Devices with Advantech RISC Platforms
The security of your device systems and software is critical for your customers. Heightened cyber-attacks, stringent privacy requirements, and increased breach risks all demand that security is baked into your product design, not slapped on as an afterthought.
Managing vulnerabilities: The importance of security notification and how to leverage Timesys’ solution
Security Is Important
No matter what industry you’re in, maintaining the security of your software is vital. It may be obvious that medical devices need to protect patients and their privacy, but a range of consumer gadgets fueling the IoT have also been targeted and used to cause real damage.
Google Project Zero team discovered a method to read privileged memory from user space by utilizing CPU data cache timing to leak information out of mis-speculated execution. Variants of this issue are known to affect many modern processors, including certain processors by Intel, AMD and ARM. For more details refer to this blogpost.
This blog aims to introduce the concept of Trusted Execution Environment (TEE) and how end users can leverage open source software to safely deploy applications that require handling confidential information.
The ever-increasing demand for connected embedded systems is driving innovation in Industrial IoT (IIoT), including designs with connected sensors, robust CPU processing, low power, and security designed and built into products from the earliest stages.
Secure boot ensures only authenticated software runs on the device and is achieved by verifying digital signatures of the software prior to executing that code. To achieve secure boot, processor/SoC support is required. In our experience, some of the more secure boot friendly processors with readily available documentation are NXP i.MX, Xilinx Zynq, and Atmel SAMA5 series. Some TI Sitara processors support secure boot, but might involve TI factory programming of signing keys and custom part numbers.
Discover IDE-assisted software development best practices that can help you minimize the number of challenges you encounter and reduce development delays when building your value-add embedded application.
This four-session webinar series will utilize open source Linux and Timesys’ TimeStorm IDE for embedded application- and system-level development. You’ll see how TimeStorm provides a consistent development experience while providing application developers with the flexibility they need to be more efficient and productive.
Embedded devices have unique security needs ranging from IP protection, anti-cloning / anti-counterfeit capability, device software integrity, user data protection, securing network communication, device authentication and ability to run only trusted applications. A wide range of open source technologies are available that can help implement the aforementioned security requirements. However, it is not always apparent which mechanisms are best suited for a given use case, resulting in a steep learning curve. This blog series aims at giving a high-level overview of the different methods to secure your product and help accelerate your trusted software deployment.
The Internet of Things (IoT) has quickly led to the deployment of ubiquitous, unattended devices throughout our homes, offices, factories and public spaces. In this continuously expanding connected world of devices and IoT, the need to update/upgrade your product’s software/firmware is a certainty. There is no single software update approach that fits all, but there are key questions you should consider when designing your approach. They are: Why, When, What and How.
