Setting a New Standard for Cybersecurity – The Cyber Resilience Act adoption

In October this year, the European Union Council adopted the Cyber Resilience Act (CRA), a groundbreaking regulation designed to enhance cybersecurity for digital products. The CRA applies to a wide range of products with digital elements, including hardware, software, and services such as cloud computing and remote data processing. By focusing on lifecycle security and secure-by-design principles, the CRA establishes a new benchmark for cybersecurity standards, urging manufacturers to embed protections at every stage of a product’s development and deployment. 

“The Cyber Resilience Act represents a turning point for cybersecurity, demanding a proactive approach to protecting digital products.” – Nils Albartus, Embedded Security Specialist and Technical Marketing Manager at Emproof.  

Key mandates and their implications: 

1. Risk assessment and secure-by-design 

Manufacturers are to adopt a risk-based approach to product development, identifying potential vulnerabilities early in the design phase. Security must be an integral part of the product’s lifecycle, not an afterthought, with secure-by-design principles. This includes implementing preventive measures and ensuring that design choices do not introduce new risks. Manufacturers must also perform comprehensive risk assessments to understand potential threats and define countermeasures. 

This mandate ensures products are inherently secure, reducing attack vectors before they can be exploited. For embedded systems and legacy devices, the challenge lies in retrofitting security into existing architectures without introducing vulnerabilities. 

Timeline for the CRA proposal, adoption and compliance.

2. No known exploitable vulnerabilities at release 

Products will need to be free of known vulnerabilities when they are introduced to the market. Manufacturers must continuously monitor their products and issue timely updates to address newly discovered flaws. Regular vulnerability assessments and penetration tests are required to identify exploitable weaknesses. Manufacturers must also implement processes for secure updates to ensure that new patches do not compromise product integrity. This requirement prevents attackers from exploiting known flaws, ensuring that products are resilient at launch and throughout their operational life. 

3. Data confidentiality and integrity 

Sensitive data stored within a product must remain confidential and protected from unauthorised modification and unofficial access. The integrity of the firmware and other critical components must be verifiable to prevent tampering. This is to safeguard both intellectual property and user data, ensuring trust in connected devices. 

4. Incident mitigation and resilience 

Products must be capable of detecting and responding to cyberattacks, this includes transitioning to a safe state when an attack is detected and minimising the impact on functionality and security. Logs and monitoring hooks should also be enabled for incident tracking and response. These measures ensure that even when attacks do occur, their impact is contained, preserving the system and user safety. 

5. Attack surface reduction 

The attack surface of a product (the exposed points susceptible to exploitation) must be reduced as much as possible. Products must employ mechanisms such as exploit mitigation and anti-tampering protections to make it harder for attackers to exploit vulnerabilities. By reducing the attack surface the opportunities for maliciously compromised devices, particularly in the context of embedded systems, are limited. 

U.S. Cybersecurity Frameworks Compared to the CRA 

While the EU’s Cyber Resilience Act sets a clear, comprehensive framework for cybersecurity across digital products, the United States does not have a direct equivalent. However, several frameworks, regulations, and legislative efforts in the U.S. serve similar objectives. For example, the NIST Cybersecurity Framework (CSF) provides widely-adopted guidelines for cybersecurity best practices, and Executive Order 14028 focuses on improving the nation’s cybersecurity, particularly in federal and critical infrastructure sectors. Additionally, the Federal Risk and Authorization Management Program (FedRAMP) ensures cybersecurity standards for cloud services used by federal agencies. These frameworks, while influential, are often fragmented and sector-specific, unlike the broader, unified scope of the CRA. If the U.S. were to create a regulation similar to the CRA, it would likely consolidate existing frameworks and impose stricter cybersecurity standards for all digital products. 

How Emproof Nyx can help simplify CRA Compliance 

Emproof Nyx delivers robust support to help companies achieve compliance with the CRA through its binary transformation technology. By addressing memory-based vulnerabilities such as buffer overflows and code injections, Emproof Nyx ensures products are resilient against common attack vectors. Its deterministic algorithms ensure that no new vulnerabilities are introduced during deployment, providing manufacturers with confidence in their security measures. With the ability to integrate directly at the binary level, it is an ideal solution for retrofitting to legacy devices, extending their lifespan without requiring source code access. 

Tim Blazytko, Chief Scientist & Head of Engineering at Emproof: 

“The Cyber Resilience Act introduces complex mandates, but it also offers a chance to elevate product security. Emproof Nyx simplifies compliance for embedded systems by addressing core challenges like memory safety, and tamper resistance. Our goal is to enable manufacturers to meet CRA requirements while protecting their intellectual property and ensuring system resilience in the face of modern threats.” 

Emproof Nyx: a proactive approach 

To prevent the exploitation of known vulnerabilities, Emproof Nyx employs advanced protections such as stack canaries and control flow integrity. This pre-emptive approach ensures that protected products remain resilient against both existing and emerging threats. 

Further safeguarding is provided through data confidentiality by its powerful combination of code obfuscation, encryption, and anti-tampering measures. These features prevent reverse engineering approaches and ensure that the firmware remains unmodified and operates as intended.  

Attack Detection and Response with Emproof Nyx 

When exploits are detected, Emproof Nyx helps mitigate their impact by offering configurable safe states, allowing manufacturers to define controlled error responses that limit operational disruptions. Its capabilities, including logging hooks or custom responses, for example entering a pre-defined safe state, ensure seamless compatibility with existing security monitoring systems, enabling rapid detection and response. 

Its advanced obfuscation techniques further enhance security by making firmware reversing and intellectual property theft far more challenging, providing manufacturers with robust defences against unauthorised modifications and exploitation. 

Meeting the CRA Requirements 

The CRA represents a major shift in cybersecurity regulations, but manufacturers who start their compliance journey now can gain a competitive edge. By integrating solutions like Emproof Nyx, organisations can meet regulatory demands while enhancing the security and reliability of their products.
