ISO/IEC 27031:2019 - Guidelines for ICT Continuity

Overview

ISO/IEC 27031:2019 is an international standard that provides guidelines for Information and Communication Technology (ICT) continuity. The standard is part of the ISO/IEC 27000 family of standards for information security management. Published in 2019, this standard offers a set of best practices and recommendations for organizations to ensure the continuity of their ICT services in the event of disruptions or disasters.

Importance of ICT Continuity

In today's digital age, ICT services play a critical role in the operation of organizations. Disruptions to these services can have significant impacts on business operations, leading to financial losses, reputational damage, and compromised data. Ensuring ICT continuity is essential for organizations to maintain their operations, protect their assets, and provide services to their customers.

Key Components of ISO/IEC 27031:2019

The standard focuses on the following key components:

  1. ICT Continuity Planning: Establishing a plan to ensure ICT services can be restored quickly in the event of a disruption.
  2. Risk Assessment and Management: Identifying and mitigating risks to ICT services.
  3. ICT Service Continuity: Ensuring that ICT services can be maintained or restored to an acceptable level in the event of a disruption.
  4. Crisis Management and Communication: Establishing procedures for crisis management and communication.

Benefits of Implementing ISO/IEC 27031:2019

Implementing the guidelines outlined in ISO/IEC 27031:2019 can bring several benefits to organizations, including:

  1. Improved ICT Service Continuity: By having a plan in place, organizations can ensure that their ICT services are restored quickly in the event of a disruption.
  2. Reduced Downtime: By identifying and mitigating risks, organizations can reduce the likelihood and impact of disruptions.
  3. Enhanced Business Resilience: By ensuring ICT continuity, organizations can maintain their operations and protect their assets.
  4. Compliance with Regulatory Requirements: Implementing the standard can help organizations demonstrate compliance with regulatory requirements related to ICT continuity.

How to Implement ISO/IEC 27031:2019

To implement the guidelines outlined in ISO/IEC 27031:2019, organizations can follow these steps:

  1. Perform a Risk Assessment: Identify potential risks to ICT services.
  2. Develop an ICT Continuity Plan: Establish a plan to ensure ICT services can be restored quickly in the event of a disruption.
  3. Implement Risk Mitigation Measures: Implement measures to mitigate identified risks.
  4. Test and Review the Plan: Regularly test and review the ICT continuity plan to ensure it remains effective.

Conclusion

ISO/IEC 27031:2019 provides guidelines for organizations to ensure the continuity of their ICT services. By implementing these guidelines, organizations can improve their ICT service continuity, reduce downtime, and enhance their business resilience. As the reliance on ICT services continues to grow, the importance of implementing standards like ISO/IEC 27031:2019 will only continue to increase.

The ISO/IEC 27031 standard serves as the international guideline for Information and Communication Technology (ICT) readiness for business continuity. It focuses on ensuring that an organization's IT infrastructure and systems can support critical business functions during and after a disruption.

As of May 2025, a major update was released—ISO/IEC 27031:2025—which replaces the original 2011 version to better address modern cyber threats and cloud-based environments. Key Components of ISO 27031

The standard provides a structured approach, often referred to as ICT Readiness for Business Continuity (IRBC), covering several core areas:

Alignment with Business Objectives: It bridges the gap between IT disaster recovery and broader business continuity management (BCM), typically governed by ISO 22301.

Recovery Targets: It establishes clear technical requirements for Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) based on business impact analyses.

The Six Categories of IRBC: Guidance is organized around six main elements to ensure a holistic recovery strategy:

Skills & Knowledge: Identifying personnel who understand how to run critical ICT services.

Facilities: Secure locations and environmental conditions for infrastructure. Technology: Critical hardware and software assets. Data: Availability and restoration of critical information.

Processes: Documented steps for incident response and restoration. ISO/IEC 27031:2019 - Guidelines for ICT Continuity Overview

Suppliers: Management of third-party vendors and external dependencies. What’s New in the 2025 Revision?

The ISO/IEC 27031:2025 update introduced several critical changes to handle current technological landscapes:

Strategic Anchoring: It shifts from a purely technical "IT recovery" focus to a strategic "organizational resilience" approach.

Cloud & Third-Party Services: Explicit guidance on managing resilience in extended digital ecosystems, including cloud providers.

Operational Workarounds: Clause 6.6a now explicitly requires organizations to have manual workarounds if ICT cannot meet RTO/RPO targets.

Integration: Stronger mandatory links with ISO/IEC 27001 for information security and incident response.

You cannot use ISO 27031 to replace ISO 22301. However, an ISO 22301-certified organization that ignores ISO 27031 will usually fail a BCM audit because the technical recovery details are missing.
