ISO 27001:2022 Annex A 8.28 Checklist Guide

ISO 27001 A.8.28 Secure Coding Checklist

Implementing A.8.28 Secure Coding under the ISO 27001:2022 framework is a critical task requiring strategic execution, continuous oversight, and adherence to security best practices throughout the software development lifecycle.

This control aims to ensure that security is embedded in every phase of software development, reducing the risk of vulnerabilities that could be exploited by malicious actors.

Scope of Annex A.8.28

A.8.28 Secure Coding within ISO 27001:2022 mandates that organisations implement stringent coding standards, ensure that developers are adequately trained, and establish ongoing review and improvement processes for code security. The goal is to integrate security into the very fabric of the development process, making it an intrinsic part of organisational culture and daily operations.

Implementation involves multiple aspects, including the creation of secure coding standards, developer education, rigorous code reviews, secure development environments, managing third-party components, and thorough testing. Each area presents unique challenges, especially in large, complex, or rapidly evolving organisations. These challenges can range from ensuring consistency in secure coding practices across different teams to maintaining the security of third-party components.

Why Should You Comply With Annex A.8.28? Key Aspects and Common Challenges

Challenge: Establishing consistent secure coding standards across diverse teams, especially in large or geographically dispersed organisations, can be complex. Additionally, keeping these standards up-to-date with evolving security threats is essential but challenging.

• Solution:
  • Develop a centralised set of secure coding standards based on recognised best practices (e.g., OWASP, SANS).
  • Regularly review and update these standards to reflect the latest threats and vulnerabilities.
  • Use ISMS.online’s Policy Management feature to create, communicate, and enforce these standards. Version control ensures that updates are managed efficiently, and the platform facilitates dissemination across all teams.

Training and Awareness

Challenge: Ensuring that all developers are adequately trained in secure coding practices can be difficult, especially with high turnover rates, rapid onboarding, or integration of contractors. Keeping training materials current with the latest threats is another challenge.

• Solution:
  • Develop and deploy a comprehensive secure coding training programme tailored to the technologies and languages used within your organisation.
  • Regularly update training materials to include the latest security challenges and techniques.
  • Leverage ISMS.online’s Training Management module to track training completion, ensure consistency, and maintain updated training content. This ensures that all developers are consistently trained and aware of secure coding practices.

Code Reviews and Static Analysis

Challenge: Conducting thorough code reviews and static analysis across all projects is resource-intensive and requires specialised skills. Ensuring consistency and depth in these reviews across large development teams can be challenging.

• Solution:
  • Implement a mandatory code review process for all code changes, focusing on identifying security vulnerabilities.
  • Utilise static analysis tools to automate the detection of common vulnerabilities in code.
  • Schedule regular audits of the code review process using ISMS.online’s Audit Management features. These tools facilitate the documentation of reviews and ensure consistency and depth across projects, providing clear evidence of compliance.

Secure Development Environment

Challenge: Securing the development environment to prevent unauthorised access to source code, while maintaining the integrity of version control systems, is critical. This becomes complex when multiple tools and systems are in use, or when developers work remotely.

• Solution:
  • Implement access controls to secure the development environment, ensuring that only authorised personnel can access source code.
  • Use version control systems to manage code changes and maintain the integrity of the codebase.
  • ISMS.online’s Documentation Management feature ensures secure storage and control of development documentation, including version control records, and supports access management to prevent unauthorised access.

Third-Party Components

Challenge: Validating the security of third-party libraries and components, and ensuring they are updated with the latest security patches, is challenging due to the complexity and volume of external code.

• Solution:
  • Assess the security of third-party libraries and components before integrating them into your codebase.
  • Establish a process for regularly updating these components with the latest security patches.
  • Use ISMS.online’s Supplier Management feature to monitor third-party components, ensuring they meet security standards and compliance requirements.

Testing and Validation

Challenge: Ensuring comprehensive testing and validation, including penetration testing and dynamic analysis, is resource-intensive and requires specialised skills. This is especially challenging in complex or legacy systems.

• Solution:
  • Conduct regular penetration testing and dynamic analysis to identify potential security vulnerabilities.
  • Implement automated testing tools to validate the security of code during development and deployment.
  • ISMS.online’s Incident Management and Audit Management tools support structured processes for testing and validation, ensuring that vulnerabilities are identified, documented, and addressed effectively.
