Introduction
The domain of embedded systems is changing fast. Connected devices now drive everything in our lives, from cars and medical devices to industrial automation systems and consumer electronics. As the proliferation of smart connected products continues, the number of cyberattacks targeting these devices is skyrocketing.
To tackle these security issues, the European Union has introduced the Cyber Resilience Act (CRA), which is set to become one of the most influential cybersecurity regulations for manufacturers, software developers and embedded engineers worldwide. Beginning September 2026, businesses marketing connected products in Europe will be required to meet stringent cybersecurity standards. This legislation is not only affecting European companies but also international manufacturers, Indian companies that develop embedded products for the global market.
These are not just regulations embedded engineers should know about anymore. It's a critical technical skill that will impact both product development and job prospects.
What Is the EU Cyber Resilience Act?
The EU Cyber Resilience Act (CRA) is a cybersecurity regulation designed to ensure that all digital products connected to a network maintain strong security throughout their lifecycle.
The primary goal of the act is simple: improve the cybersecurity standards of hardware and software products before they enter the market.
The regulation applies to products such as:
- IoT devices
- Automotive embedded systems
- Medical electronic devices
- Industrial automation systems
- Consumer electronics
- Smart home devices
- Wireless communication devices
- Embedded software platforms
Under this act, manufacturers must design products with cybersecurity built into the architecture instead of treating security as an afterthought.
This marks a major shift toward security-by-design engineering principles.
Key Deadlines You Cannot Miss
The Cyber Resilience Act follows a structured timeline that companies and engineers must follow.
Important deadlines include:
2025
Organizations begin preparing products and security frameworks for compliance.
September 2026
Mandatory compliance requirements begin rolling out for manufacturers.
December 2027
Full implementation becomes mandatory for all eligible digital products sold within the European market.
This means engineering teams must begin implementing security practices immediately to avoid compliance issues later.
Companies waiting until the deadline may face serious development delays and regulatory risks.
Who Does the CRA Apply To?
The CRA applies broadly to organizations involved in designing, manufacturing, or distributing digital products.
This includes:
Product Manufacturers
Companies building hardware devices that connect to the internet or communicate digitally.
Embedded Software Developers
Teams developing firmware, bootloaders, real-time operating systems, and communication protocols.
IoT Product Companies
Businesses manufacturing smart devices, wearables, and connected appliances.
Automotive Electronics Manufacturers
Companies working on ECUs, ADAS systems, infotainment systems, and vehicle communication networks.
Industrial Automation Companies
Manufacturers producing PLC systems, robotics controllers, and smart factory devices.
Even if a company operates outside Europe, selling products into EU markets requires compliance.
This directly affects many engineering companies in India working with overseas clients.
The 5 Technical Requirements Every Embedded Engineer Must Implement
The Cyber Resilience Act introduces strict technical security standards. Every embedded engineer should understand these requirements.
1. Secure Boot
Secure Boot ensures that a device runs only trusted and authenticated firmware during startup.
Without Secure Boot, attackers can replace firmware with malicious code and gain control of the device.
Secure Boot works by verifying digital signatures before execution.
Implementation methods include:
- Cryptographic signature verification
- Hardware root of trust
- Bootloader integrity validation
- Trusted Platform Module integration
Microcontrollers commonly supporting Secure Boot include:
- STMicroelectronics STM32 series
- NXP Semiconductors processors
- Texas Instruments embedded systems
- Microchip Technology controllers
Secure Boot will become a standard requirement for future embedded development.
2. No Default Passwords
Many IoT devices still ship with weak default credentials such as:
- admin/admin
- 123456
- password
Attackers frequently exploit these devices using automated scanning tools.
Under the CRA, products cannot rely on universal default passwords.
Recommended security practices include:
- Force password change during first boot
- Generate device-specific credentials
- Multi-factor authentication where possible
- Password encryption in secure storage
- Eliminate hardcoded credentials in firmware
Embedded engineers must now treat authentication security as a critical development priority.
3. Secure OTA Firmware Updates
OTA (Over-the-Air) updates allow devices to receive firmware updates remotely.
However, insecure update systems create serious security vulnerabilities.
The CRA requires firmware update systems to be secure and protected from tampering.
Secure OTA implementation requires:
- Firmware encryption during transmission
- Digital signature verification
- Version rollback protection
- Update package integrity validation
- Secure communication protocols like TLS
Without secure update architecture, attackers may install malicious firmware remotely.
Engineers developing connected products must now prioritize secure firmware delivery pipelines.
4. Software Bill of Materials (SBOM)
A Software Bill of Materials (SBOM) is essentially a complete list of all software components used inside a product.
It documents:
- Operating systems
- Open-source libraries
- Communication stacks
- Third-party dependencies
- Firmware modules
- Security libraries
Why does this matter?
Modern embedded systems heavily depend on open-source software. If a vulnerability appears in one dependency, manufacturers must quickly identify affected products.
Popular tools for generating SBOM include:
- CycloneDX
- SPDX
- GitHub dependency scanners
This requirement is pushing embedded teams toward stronger software dependency management practices.
5. Vulnerability Reporting Within 24 Hours
One of the strictest CRA requirements is rapid vulnerability reporting.
If manufacturers discover a security vulnerability affecting their product, they must report it quickly.
The regulation requires reporting within 24 hours after identifying actively exploited vulnerabilities.
This creates major operational changes for engineering teams.
Required practices include:
- Security monitoring systems
- Incident response procedures
- Log collection infrastructure
- Vulnerability management workflows
- Security patch deployment pipelines
Engineers must now think beyond development and consider long-term product security maintenance.
Why This Matters for Embedded Engineers in India
India has become a major global hub for embedded development and product engineering.
Thousands of engineers work on projects for European clients across industries such as:
- Automotive electronics
- IoT development
- Semiconductor design
- Industrial automation
- Consumer electronics
- Healthcare devices
As European companies adopt CRA compliance, they will expect outsourcing partners in India to follow the same standards.
This means engineers lacking cybersecurity skills may struggle to remain competitive.
Understanding secure firmware development will soon become a major career advantage.
How CRA Is Changing Embedded Job Requirements in 2026
Traditional embedded development focused mainly on:
- C programming
- Microcontrollers
- RTOS development
- Communication protocols like UART, SPI, I2C, CAN
However, companies are now actively seeking engineers with cybersecurity knowledge.
Skills becoming highly valuable include:
- Secure Boot implementation
- Cryptography fundamentals
- Secure firmware architecture
- TLS and encrypted communication
- Hardware security modules
- Linux security hardening
- Penetration testing basics
- OTA security design
- Vulnerability analysis
The embedded engineer of 2026 must combine software engineering with cybersecurity expertise.
CRA Readiness Checklist
Use this checklist to evaluate product readiness.
Ask the following questions:
- Does the device support Secure Boot?
- Are default passwords completely removed?
- Is firmware update transmission encrypted?
- Are firmware updates digitally signed?
- Do you maintain an SBOM for all software components?
- Is vulnerability detection actively monitored?
- Can vulnerabilities be reported within 24 hours?
- Are communication channels encrypted using secure protocols?
- Are third-party libraries regularly patched?
- Is security testing part of the development cycle?
If the answer is "No" for several points, product architecture may require immediate improvement.
Penalties for Non-Compliance
The EU Cyber Resilience Act introduces serious financial penalties for organizations that fail compliance requirements.
Possible consequences include:
Heavy Financial Penalties
Companies may face fines reaching millions of euros.
Product Sales Restrictions
Non-compliant products may be banned from European markets.
Legal Liability
Manufacturers may face legal action if security vulnerabilities cause damage.
Brand Reputation Damage
Security failures can permanently damage customer trust.
Ignoring cybersecurity regulations is no longer a manageable business risk.
Final Thoughts
The Cyber Resilience Act is the first ever sweeping reform in the design of embedded products globally.
For embedded engineers, cybersecurity is no longer a niche skill reserved for security specialists.
That's increasingly an engineering strong recommendation.
By September 2026, producers of connected products in Europe must ensure security is considered at all stages of the development.
Engineers with Secure Boot, OTA security, vulnerability management, authentication systems, secure firmware design, etc.
Indian engineers, well especially automotive and IoT and embedded Linux and industrial automation engineers, if they learn security based embedded development today can find themselves in really good jobs tomorrow.
The future of embedded engineering belongs to those who make secure, not just functional systems, they say.
