In the first part of our Security TechCast, we looked at why security must be designed into every critical system from the start. In Part 2, we go deeper — exploring how operating systems, development environments, and cryptographic frameworks combine to form a comprehensive defense strategy.

ELinOS – Embedded Linux for Critical Systems

ELinOS is more than just another Linux distribution. It is purpose-built for security and reliability, with features like a built-in configuration wizard to simplify system setup and minimize errors. Integrated closely with PikeOS, it supports hardened security principles while maintaining real-time performance for demanding applications.

CODEO – Secure Development at Every Step

A secure system begins with a secure development process. CODEO, SYSGO's integrated development environment (IDE), provides developers with a robust toolset to configure, build, and optimize embedded projects. With hundreds of configuration parameters and security-conscious defaults, CODEO helps reduce complexity and human error — two of the biggest risk factors in embedded software.

The Supply Chain Factor

Modern security isn’t limited to code — it extends across the entire supply chain. Attacks targeting third-party libraries and components are on the rise, making supply chain integrity a critical part of embedded security. SYSGO actively monitors potential vulnerabilities in open-source components and integrates safeguards to minimize exposure.

Trusted Products through Partnerships and Culture

Cryptography is a cornerstone of embedded security, but implementing algorithms correctly is as critical as selecting the right ones. SYSGO collaborates with partners like wolfSSL to ensure robust and validated cryptographic implementations, reducing risk and accelerating time-to-market.

Technology alone is not enough. Secure-by-design requires teams to embrace rigorous standards, maintain curiosity, and constantly evolve their skills to match emerging threats. New engineers are encouraged to dive deep into technical details, stay informed on safety and security standards, and collaborate across teams to keep systems resilient.

Conclusion

Security-by-design extends far beyond software features — it is a mindset applied across every layer of development, from operating systems and IDEs to cryptographic libraries and supply chain processes. By combining rigorous engineering, trusted partnerships, and a culture of continuous security awareness, SYSGO builds solutions that meet the highest standards for critical embedded systems.
