The Path to Secure-by-Design: Shaping a Resilient Cybersecurity Landscape

In the rapidly evolving digital landscape, cybersecurity has become a paramount concern for nations worldwide. The March 2023 National Cybersecurity Strategy (NCS) demonstrates a proactive approach by emphasizing the adoption of secure-by-design principles in setting cybersecurity regulations for critical infrastructure. This article delves into the significance of secure-by-design and the potential for it to become a regulatory requirement enforced through an Executive Order.

Different Interpretations of Secure-by-Design

As the concept of secure-by-design gains traction, it is imperative to understand that the term is subject to varying interpretations among product developers. While all vendors assert that their products embrace secure-by-design principles, the rationale behind these claims differs. Currently, secure-by-design remains more of a label, with each vendor asserting the security of their product based on proprietary processes.

The Need for a Standardized Definition of Secure-by-Design

To ensure the effectiveness of secure-by-design, there is a pressing need for a universally applicable standardization of the approach taken by product developers. Merely relying on subjective interpretations can lead to inconsistencies in security measures. Moreover, if secure-by-design is to shift the burden of security from users to providers, it is crucial to incorporate secure-by-design hardware into the equation.

Developing a Secure-by-Design Specification

To overcome the challenges of current perceptions, the development of standard processes, collectively known as a secure-by-design specification, is crucial. This specification would serve as a playbook for product developers, guiding them in implementing secure-by-design principles effectively. By establishing clear guidelines and best practices, these standards can help drive the adoption of robust cybersecurity practices across critical industries.

Acknowledging the Influence of CISA and Preparation for the Future

The Cybersecurity and Infrastructure Security Agency (CISA) plays a pivotal role in shaping regulations and mandating cybersecurity measures. The persistence of regulatory bodies like CISA should not be underestimated. As secure-by-design becomes an increasingly important requirement, developers can benefit by preparing early to align their products with impending regulations.

Challenges of Regular Audits in Enforcing Secure-by-Design

While audits are commonly used to ensure compliance, they can be expensive and time-consuming. Additionally, the effectiveness of audits can be undermined if they become self-defeating or are not conducted consistently. Exploring alternative methods that strike a balance between ensuring security and reducing the burden on both product providers and users becomes crucial in effectively enforcing secure-by-design.

Expanding Secure-by-Design into Hardware

While the current focus is primarily on software, for secure-by-design to be fully successful, its principles must extend into hardware. Recognizing hardware vulnerabilities and implementing secure design principles in this domain will further enhance the overall resilience of critical systems. This expansion inevitably calls for collaborative efforts among stakeholders to establish comprehensive and cohesive standards.

As highlighted in the March 2023 National Cybersecurity Strategy, secure-by-design is not a passing trend but a pivotal element in safeguarding critical infrastructure. The establishment of a standardized secure-by-design specification is crucial to ensure consistent implementation across the industry. By proactively embracing secure-by-design principles and staying ahead of regulatory requirements, developers can better protect their systems and contribute to a resilient cybersecurity landscape. It is incumbent upon all stakeholders, from regulators to developers, to collectively strive for a secure-by-design future.
