KernelCare for IoT adds support for Raspbian

KernelCare for IoT adds support for RaspbianSo, you have your shiny new Raspberry Pi, a great idea to use it, and the technical skill to pull it off successfully. It doesn’t matter if it’s as a network print server, a dedicated media center, a retro arcade cabinet or a home automation system. The Pi has you covered.

 

You configure it to your heart content, adjust every parameter and setting to squeeze out the performance you need, create your best invention. The Pi is foremost an enabling platform, letting you give free rein to your creativity.

 

And then you let your project run. After the initial set up and configuration, the Pi can be hidden away and forgotten, while it sits in your home network performing its function. And maybe you don’t follow IT security news, or miss a relevant vulnerability report amongst the flood of CVEs, or simply don’t think anyone would target your Pi to exploit any weaknesses. The thing is, hackers love this kind of device because they present an entry point into your network.

KernelCare Live IoT Patching integrates with Microsoft Azure IoT Hub

KernelCare Live IoT Patching now fully integrates with Microsoft Azure IoT Hub

Billions of IoT devices are transforming the capabilities of industrial control systems (ICS): delivering low cost, low power computing to achieve efficiency and automation. But the unique characteristics of these devices can also turn ICS into somewhat of a management and security headache.

As always, tools emerge to relieve these challenges – for example, take Microsoft Azure IoT Hub. It is common for IoT devices to proliferate and it makes tracking and managing IoT devices very challenging. Azure IoT Hub is a tool that helps organizations to catalog, manage and integrate large fleets of IoT devices.

Similarly, managing security patching across large IoT networks can be difficult – devices in ICS environments may be air-gapped and require 100% service availability. KernelCare live patching for IoT can help solve these challenges.

Today, we’re delighted to announce that KernelCare for IoT now fully integrates with Device Update for IoT Hub from Microsoft, which is currently in preview in select Azure regions. Let’s take a look.

Patch Raspberry Pi systems without a reboot for free with KernelCare

Cover-1 (1)-minYour Raspberry Pi might be a hobby or a critical part of your home network, but regardless of its purpose it can be a target for hackers. You may be familiar with common security for Raspberry Pi such as requiring a password to use sudo, changing the default sudo password, changing your default username, and the use of key-based authentication for SSH. These strategies improve your security, but the most critical part of Raspberry Pi protection is keeping it up to date with the latest security patches. KernelCare will help you live patch your Raspberry Pi device automatically for free.

Meet The IoT Cybersecurity Improvement Act Terms With KernelCare

Meet The IoT Cybersecurity Improvement Act Requirements With KernelCareLast week, the US Congress officially signed a bipartisan law, The Internet of Things Cybersecurity Improvement Act of 2020, or the IoT Cybersecurity Improvement Act of 2020. Sponsored by Reps. Will Hurd (R-Tex) and Robin Kelly (D-Ill), the law was made to establish that the government purchases only secure devices and closes existing vulnerabilities. The legislation mostly affects U.S. federal government applications, vendor partners, equipment manufacturers and stakeholders that deal with the federal government. However, this law has the potential to have ripple effects that extend beyond security safeguards for government entities, with those in the private industry and consumers more than likely also benefiting from new connected device standards.

Keeping Your Medical Device Security Compliant with Live Patching

Keeping Your Medical Device Security Compliant with Live PatchingToday, the security of medical devices is becoming extremely important to assure customers and patients who interact with your devices that their health and personal information is taken seriously. Globally, regulators are increasingly requiring and verifying that devices are as secure as possible before and after product release. To continually address cybersecurity risks to keep patients safe and better protect public health, medical device manufacturers must comply with federal regulations. 

The IoT Surge And Live Patching At The Edge

The IoT surge and live patching at the edge

The Internet of Things (IoT) has been adopted by an increasing number of enterprises recently, and it has become an essential part of edge computing. IoT projects are being added to the enterprise because they can bring value to the business by adding an intelligence and automation capability in situations where it wasn't available before. However, with the amount of personal or sensitive data being stored at the edge, you could be at risk for a data breach through devices in your network that are unpatched for long periods of time - if ever. 

Securing ARM-based Linux IoT Devices Requires Live-Patching the Kernel

ARM-based Linux IoT Devices Requires Live-Patching the Kernel

The IoT is an integral part of many network infrastructures and a feature of everyday life for consumers. On the enterprise level, there are smart buildings, public utilities, and smart factories that rely upon online connectivity to operate smoothly via a network of physical nodes. Companies invest trillions of dollars in IoT tech to develop the most cutting-edge technologies and meet future economic challenges.

Best Practices for Compliance in IoT: The Role of Live Patching

Best Practices for Achieving Compliance in IoT: The Role of Live Patching

The Industrial Internet of Things (IIoT or “IoT” for short) consists of billions of devices deployed across industrial facilities and public infrastructure. While a boon to productivity and data-driven business, the IoT creates cybersecurity risks. The technology is itself vulnerable, but IoT devices also offer hackers an easy point of entry into corporate networks. Indeed, according to a 2019 Ponemon Institute study, unsecured connected devices accounted for 26% of security incidents, up from 15% the year before. Since the beginning of 2020, the Verzion has analysed 157,525 incidents of data breaches, 72% of which involved large business victims. Being a part of this statistics is a bleak perspective for corporations and industries that do not practice the best IoT compliance frameworks.

Best Embedded Linux Development Tools

Best Linux Embedded Development tools

Most developers are used to a graphical interface for development, so when diving into the world of IoT and embedded Linux development, it’s a new experience that requires more low-level programming and command-line execution. If you ever want to build systems such as IoT, GPS, automotive technology, manufacturing, or any other low-level electronics programming, you need an embedded development environment to work with. 

Stack unwinding in AArch64 processors: what is it and how it works

Stack unwinding in AArch64 processors_

For the past nine months, KernelCare’s Linux kernel live patching software has supported ARMv8 (AArch64) in addition to x86_64 (Intel IA32/AMD AMD64). To get KernelCare running on Arm, we needed a stack frame unwinder.

This article explains what they are, what they’re used for, and why we had to write our own.
