Welcome back to Kimova AI’s ISO 27001 auditing series. In our previous article, we discussed the changes in Control A.5.20: Addressing Information Security Within Supplier Agreements. Today, we will examine Control A.5.21: Managing Information Security in the ICT Supply Chain, comparing the 2013 and 2022 versions, and highlighting key updates.

Control A.5.21: Managing Information Security in the ICT Supply Chain

Control A.5.21 focuses on ensuring that information security risks are managed effectively throughout the Information and Communications Technology (ICT) supply chain. Given the critical role of ICT in modern business operations, this control is essential for maintaining the integrity, availability, and confidentiality of information across all levels of the supply chain.

Key Changes in A.5.21

  1. Broader Definition of the ICT Supply Chain
    • 2013 Version: The 2013 version primarily addressed traditional ICT suppliers, focusing on hardware, software, and network service providers.
    • 2022 Version: The 2022 update expands the definition of the ICT supply chain to include a wider range of entities, such as cloud service providers, data centers, and outsourced IT services. This broader scope reflects the growing complexity of ICT supply chains and the need to manage risks across all components of the supply chain.
  2. Enhanced Risk Management Practices
    • 2013 Version: While risk management was addressed, the 2013 version provided limited guidance on how to manage risks specifically within the ICT supply chain.
    • 2022 Version: The updated version introduces more detailed guidance on risk management practices specific to the ICT supply chain. This includes conducting thorough risk assessments, considering the impact of each supplier on the organization’s overall security posture, and implementing appropriate controls to mitigate identified risks. The aim is to ensure a comprehensive approach to managing information security risks in the ICT supply chain.
  3. Integration with Business Continuity Planning
    • 2013 Version: Business continuity planning was mentioned but not strongly integrated with ICT supply chain management.
    • 2022 Version: The 2022 update emphasizes the need to integrate ICT supply chain management with the organization’s overall business continuity planning. This includes ensuring that suppliers have robust continuity plans in place and that these plans are aligned with the organization’s own continuity strategies. This integration helps ensure that the organization can maintain operations in the event of a disruption in the ICT supply chain.
  4. Increased Focus on Supply Chain Transparency
    • 2013 Version: Supply chain transparency was not a primary focus in the 2013 version.
    • 2022 Version: The updated version highlights the importance of supply chain transparency, including the need for organizations to have visibility into their suppliers’ security practices and the security practices of their suppliers’ suppliers. This increased focus on transparency helps organizations better understand and manage the risks associated with the ICT supply chain.

Implications of These Changes

  1. Comprehensive Risk Management
    • The broader definition of the ICT supply chain and the enhanced risk management practices ensure that organizations can effectively manage information security risks across all components of the supply chain, reducing the likelihood of security incidents.
  2. Improved Business Continuity
    • By integrating ICT supply chain management with business continuity planning, organizations can better prepare for and respond to disruptions, ensuring that critical operations can continue even if a supplier experiences a security breach or other issue.
  3. Greater Supply Chain Visibility
    • The increased focus on supply chain transparency provides organizations with greater visibility into the security practices of their suppliers, helping them identify and address potential risks before they can impact the organization.

Conclusion

The updates to Control A.5.21 in ISO 27001:2022 reflect the growing complexity of ICT supply chains and the need for a more comprehensive approach to managing information security risks. By broadening the scope of the ICT supply chain, enhancing risk management practices, integrating supply chain management with business continuity planning, and increasing supply chain transparency, the standard helps organizations protect their information assets more effectively.
