Cyber Resilience Act (CRA) for embedded systems
The Cyber Resilience Act (CRA) of the European Union introduces mandatory cybersecurity requirements for Products with Digital Elements, directly impacting embedded systems used in Industrial IoT and connected devices.
From a technical perspective, CRA compliance requires embedded platforms to implement a secure lifecycle (secure SDLC) across firmware and system software, including:
-
Secure boot and hardware root of trust
-
Authenticated and resilient OTA/field updates (signing, rollback protection)
-
Vulnerability management processes (CVE monitoring and patch delivery)
-
Software Bill of Materials (SBOM) for all firmware components
-
Hardening of embedded Linux / RTOS configurations
-
Defined security support period aligned with the product lifecycle
This shifts embedded development from a static firmware model to a continuously maintained software stack.
For Industrial IoT architectures based on embedded Linux, production-ready secure build layers can accelerate compliance.
An example is Atenys, a secure layer for the Yocto Project developed by Engicam, which integrates secure boot, fail-safe update mechanisms, and vulnerability scanning into the build pipeline:
With CRA enforcement approaching (full applicability in 2027), integrating security-by-design at the BSP and firmware level is becoming a core requirement for embedded product engineering rather than an optional enhancement.
