The Cybersecurity and Infrastructure Security Agency’s Secure by Design initiative recently reached its one-year milestone, marking the occasion with a blog post highlighting its accomplishments over the past year. Launched just after the National Cybersecurity Strategy, which emphasized secure design as a crucial element of the Biden Administration’s cybersecurity approach, the initiative aimed to shift the responsibility of security from end users to technology manufacturers.

One of the key aspects of the Secure by Design initiative has been its focus on raising awareness of the importance of secure design. By providing principles and guidance for technology providers and software developers, as well as sharing regular updates through blogs and alerts, CISA has significantly increased awareness of secure design both in the U.S. and globally. Collaborative efforts with 16 other nations have further magnified the impact of this initiative, drawing media attention to the issue and making secure design a prominent topic in conversations about software and product security.

In terms of practical action, the announcement of liability for software providers in the National Cybersecurity Strategy was a major step forward. While the actual introduction of liability will require legislative support, requiring companies to attest to using secure development practices when supplying software to the federal government is a significant move towards building security into public procurement processes. This shift in responsibility from end users to manufacturers is essential for ensuring that software is designed securely from the outset.

However, attention to detail is crucial for the success of any secure design initiative. While CISA’s guidance on secure design provided valuable instructions, it fell short in explaining how to effectively deploy threat modeling, a fundamental element of designing secure software. Feedback from threat modelers highlighted the need for more detailed guidance on threat modeling implementation, urging CISA to expand its recommendations in this area.

Looking towards the future, CISA has outlined three new focus areas for its secure design efforts, including encouraging customers to prioritize security, addressing economic forces impacting software security, and integrating security into educational programs. These initiatives are promising steps towards further advancing secure design practices and addressing the ongoing challenges in the software development industry.

Overall, the Secure by Design initiative has been successful in raising awareness, taking practical action, and setting a vision for the future of secure design. While there are areas for improvement, such as providing more detailed guidance on threat modeling, the initiative’s impact has been significant. With a grade of B+ overall, the Secure by Design initiative has laid a strong foundation for enhancing security practices in software development and ensuring a more secure digital landscape for the future.
