With the rapid advancement of technology in industries, cybersecurity has become a crucial necessity to protect an organization’s assets from malicious attacks. In order to ensure compliance with industry standards and regulations while protecting against potential security vulnerabilities, requirements management is essential. This helps organizations save time and money while delivering secure and compliant software products.

Effective requirements management is critical for any organization seeking to ensure the security and compliance of its products or services. In the software requirement specifications, cybersecurity requirements should be integrated to address authentication, authorization, data integrity, and access control issues. By doing so, organizations can avoid costly mistakes resulting from a lack of attention to detail regarding security best practices.

Cybersecurity is a major concern for embedded systems, encompassing all of the technology and operations used to safeguard devices and their platforms and networks against cyberattacks or hacking. Development teams for embedded systems already know many concepts and techniques to mitigate security risks, such as coding rules, dedicated RTOS, cryptography techniques, static and dynamic analysis, and more. However, one aspect that is often overlooked is requirements management and traceability.

Even though security standards like IEC 62443 / ISA Secure require managing and tracing security requirements throughout the development and testing lifecycle, many engineers are unsure how to efficiently comply with these requirements and which types of checks and processes apply to requirements management. 

Therefore, Micaël Martins, European Sales Leader at Visure, delivered a thorough presentation on “How to Write and Manage Requirements for Cybersecurity Embedded Projects” at the Electronics of Tomorrow 2023 in Denmark. 

Why Requirements Management is so important in Embedded Safety and Security Standards

Requirements management is particularly important in the context of embedded safety and security standards due to the critical nature of the systems involved. Here’s why:

1. Compliance with Standards: Embedded safety and security standards, such as ISO 26262 for automotive systems or IEC 61508 for industrial control systems, define rigorous requirements for ensuring the safety and security of these systems. Requirements management helps in capturing, documenting, and managing these standards-specific requirements, ensuring compliance throughout the development lifecycle.
2. Risk Identification and Mitigation: Embedded safety and security standards require a thorough understanding of potential risks and their mitigation strategies. Requirements management helps identify and assess safety and security risks, allowing for the development of appropriate requirements to address these risks. It also enables traceability between risks, requirements, and the implemented solutions, ensuring that safety and security measures are adequately implemented.
3. Traceability and Accountability: Safety-critical systems demand traceability and accountability for each requirement. Requirements management ensures that safety and security requirements are properly traced from their origins to the design, implementation, and testing stages. This traceability helps demonstrate compliance with standards, facilitates change management, and enables effective impact analysis when modifications or updates are required.
4. Verification and Validation: Embedded safety and security standards require extensive verification and validation processes to ensure that the systems meet the specified requirements. Requirements management supports the planning and execution of these activities by providing clear and testable requirements, facilitating the identification of suitable verification and validation techniques, and enabling the establishment of traceability between tests and requirements.
5. Change Management: Safety and security standards often undergo updates and revisions to address emerging threats and industry advancements. Effective requirements management enables organizations to adapt to these changes by efficiently incorporating new requirements, updating existing requirements, and managing the impact on the development process. It ensures that the safety and security aspects of the embedded systems remain up-to-date and aligned with the evolving standards.
6. Documentation and Audibility: Embedded safety and security standards often require comprehensive documentation to demonstrate compliance. Requirements management ensures that all requirements, along with their associated rationale, verification and validation evidence, and change history, are properly documented. This documentation supports audits, assessments, and regulatory compliance, providing evidence of due diligence and adherence to safety and security standards.

In the realm of embedded safety and security standards, effective requirements management is crucial to ensure compliance, mitigate risks, maintain traceability, support verification, and validation, manage changes, and provide auditable documentation.

This includes verifying that the tools accurately capture, manage, and trace requirements throughout the development lifecycle.

Relative Cost Of Fixing An Error In Requirements

The cost of fixing an error in requirements can vary depending on various factors. Here are some factors that can influence the relative cost:

1. Stage of the project: The cost of fixing a requirements error can be significantly lower if the error is identified and corrected early in the project lifecycle, such as during the requirements gathering and analysis phase. On the other hand, if the error is discovered during later stages of development or after the product has been implemented, the cost of rectifying it can be much higher, as it may require rework, design changes, or even product recalls.
2. Magnitude of the error: The severity and impact of the requirements error also affect the cost of fixing it. Minor errors or inconsistencies may be relatively easy and inexpensive to rectify, while major errors that affect critical functionalities or safety requirements can be significantly costlier to address.
3. Impact on downstream activities: Requirements errors can have a ripple effect on subsequent development activities. If the error propagates through the design, coding, and testing phases, it can result in significant rework and delays, leading to increased costs. Additionally, if the error goes unnoticed until later stages of the project, it may require modifications to existing components, interfaces, or system architecture, further driving up the cost of correction.
4. Discovery and correction process: The cost of fixing a requirements error depends on the efficiency and effectiveness of the discovery and correction process. If the error is identified through thorough reviews, inspections, or validation activities, it can be addressed earlier, reducing the cost. Conversely, if the error remains undetected until it causes issues in the field, the cost of addressing it can be much higher, potentially involving customer support, product recalls, or legal ramifications.
5. Organizational processes and culture: The maturity of an organization’s requirements management processes and its culture around quality and error prevention also play a role. Organizations with robust requirements management practices, including peer reviews, quality gates, and traceability, are more likely to catch and rectify errors early, minimizing the associated costs.

It is worth noting that preventing requirements errors in the first place through effective requirements management, stakeholder engagement, and validation activities is typically more cost-effective than fixing errors after they have propagated into subsequent stages of development or production. Investing in thorough requirements analysis, reviews, and verification processes can help identify and address errors early, reducing the overall cost and impact on the project.
