ISO/IEC TR 24772-3:2020 provides guidance to avoid vulnerabilities in programming languages, with a specific focus on C. For teams responsible for secure software development, code review, procurement, or conformity assessment, it offers a technical document that can support risk management and engineering validation when C is used in safety-, security-, or reliability-sensitive systems. As a part of ISO/IEC TR 24772, it is best understood as a supporting reference for evaluating language-related weaknesses and improving documented evaluation practices across the development workflow.

Overview of ISO/IEC TR 24772-3:2020

ISO/IEC TR 24772-3:2020 addresses common vulnerability patterns associated with the C programming language and explains how they may be avoided in practice. The document is relevant where software quality workflows depend on technical review, secure coding guidance, and controlled implementation methods. It can help organizations align engineering documentation with known language risks, especially when preparing a compliance reference for embedded systems, product evaluation, or software assurance activities. Its role is typically advisory, supporting structured assessment rather than defining a conformance test.

Compliance applications of ISO/IEC TR 24772-3:2020

In compliance workflows, ISO/IEC TR 24772-3:2020 may be used during code specification review, secure development planning, and verification activities for C-based applications. It is often useful in environments where software supports electrical equipment, industrial control systems, or other engineered products that require disciplined technical validation. Procurement teams and laboratories may also use it as a reference when comparing development requirements, reviewing coding practices, or preparing conformity assessment evidence. The document supports consistency in testing workflows and helps frame vulnerability-focused technical assessment.

Importance of compliance with ISO/IEC TR 24772-3:2020

Using ISO/IEC TR 24772-3:2020 can reduce implementation risk by identifying language features and usage patterns that commonly lead to defects or security weaknesses. That matters for safety, interoperability, and operational consistency, particularly where C code is deployed in long-life or tightly controlled systems. For engineering and procurement teams, the document can support clearer requirements, more reliable technical validation, and better preparation for conformity assessment. It also strengthens quality assurance by making vulnerability avoidance part of documented evaluation and review processes.
