In embedded systems and IoT devices, the “boot process” is considered as the core of security. The bootloader is responsible for the loading of firmware, kernel and filesystems. In case of insecure bootloaders, anyone can violate systems to load malware at boot time, compromising the overall systems security. Let’s explore [...]
Delivering embedded software faster without compromising reliability, safety, or compliance is one of the biggest challenges in modern industrial product development. As industries adopt Industry 4.0, IoT, and smart automation, companies are asking the same question: How can we accelerate embedded software delivery while ensuring quality, certification readiness, and long-term [...]
When developing embedded Linux systems or firmware for connected devices, compliance isn’t just a final checkbox — it’s the foundation of trust, safety, and market readiness. Whether you’re building an industrial controller, smart energy device, or medical-grade sensor, proving regulatory compliance can make or break your launch timeline. In this [...]
As embedded devices continue to power critical industries—from energy and healthcare to consumer IoT—regulatory compliance has become more than a checkbox. New frameworks like the EU Cyber Resilience Act (CRA), along with CE and GPSR requirements, are reshaping how manufacturers design, document, and certify their products.Without these compliances, companies cannot [...]
Factories don’t fail in clean, predictable ways. Motors overheat, sensors drift, and power dips just when you need stability the most. When you’re building the systems that keep all of this running, the platform underneath has to be just as tough as the environment around it. That’s where the choice [...]
Embedded devices—whether automotive ECUs, IoT sensors, or industrial controllers—face increasing cyber threats during both boot and runtime. From firmware tampering to memory exploitation, attackers often target early boot stages and exploit runtime weaknesses to compromise the entire device. If you’re wondering how to secure embedded devices throughout their full lifecycle, [...]
In the potentially growing world of embedded systems, data integrity has become a big problem. According to a survey, 94% of companies manufacturing embedded systems reported a cyberattack at least once in the last 2 years. Security Weaknesses in your systems can lead to many vulnerabilities. Secure boot is one [...]
In the present world, every device is smart and controllable through the Internet. Therefore, companies spend a lot of money on ensuring the network security of embedded devices. But embedded devices are still vulnerable to attacks from different sources. Have you wondered why and how? The answer is simple. Network [...]
Kernel fitImage signing is an important step in embedded secure boot. In this technique, a public-private key pair is generated by OpenSSL. The private key is used to sign the kernel fitImage. The public key is placed in the device tree of the bootloader (uboot or barebox) which is used [...]
Rust has become one of the most loved programming languages in the last few years due to its drastic features related to memory management and low-level control. Due to its rich features it has become first language after C to be used for Linux kernel development. In this tutorial, we [...]
