The standard formalizes a six-step loop for ICT incidents:
The standard describes the concepts and principles of ICT readiness. Its primary purpose is to ensure that an organization's ICT infrastructure is capable of supporting the continuity of business operations during and after a disruptive incident.
It is applicable to any organization, regardless of size or industry, that relies on ICT systems for its operations.
ISO/IEC 27031:2011 is the definitive bridge between IT Disaster Recovery and Business Continuity Management. It shifts the focus of IT from a purely technical recovery perspective to a service-oriented readiness perspective.
While the document is a paid standard, the investment is justified for organizations seeking to mature their resilience posture. It moves an organization away from the question "Will our servers turn back on?" to the more critical question "Will our business survive the next disruption?"
Recommendation: Organizations should use ISO 27031 in conjunction with ISO 22301 (Business Continuity) and ISO 27001 (Information Security) to build a comprehensive risk management framework.

ISO/IEC 27031 is the international standard for Information and Communication Technology (ICT) readiness for business continuity.
It provides a framework to ensure your IT infrastructure can withstand, respond to, and recover from disruptive events. 🛡️ Key Purpose of ISO 27031
Bridge the gap between general business continuity and specific IT disaster recovery.
Ensure data availability and system recovery within agreed-upon timeframes.
Support other standards like ISO 22301 (Business Continuity) and ISO 27001 (Information Security Management).
Achieve non-certifiable alignment; organizations cannot get formally certified in ISO 27031, but it proves best-practice compliance. 📋 The Six Core Elements of ICT Readiness
To align with the standard, your organization should focus on six categories:
Skills and Knowledge: Ensuring staff have the necessary training to handle recovery operations.
Facilities: Securing alternative data centers, office spaces, and environmental infrastructure.
Technology: Designing systems with built-in redundancy, backups, and failovers.
Data: Implementing reliable recovery point objectives (RPO) and secure backup protocols.
Processes: Creating documented step-by-step procedures for incident response and disaster recovery.
Suppliers: Factoring third-party vendors and cloud providers into your recovery timeline. 🚀 How to Implement ISO 27031
Follow the standard Plan-Do-Check-Act (PDCA) cycle to build your framework:
Plan: Conduct a Business Impact Analysis (BIA) and define recovery time objectives (RTO).
Do: Implement technical controls, redundant hardware, and off-site data storage.
Check: Regularly test your disaster recovery plans and run simulation tabletop exercises.
Act: Update your processes based on test failures or changes in your IT environment. 📑 How to Get the PDF

ISO 27031: The Ultimate Guide to ICT Readiness for Business Continuity
In today’s digital-first world, a single IT failure can paralyze an entire organization. Whether it’s a cyberattack, a hardware failure, or a natural disaster, your business continuity depends on your Information and Communication Technology (ICT) systems staying online. That is where ISO/IEC 27031
This post explores what the standard is, how it differs from others like ISO 22301, and why it is a critical resource for any modern business. What is ISO/IEC 27031? ISO/IEC 27031:2011 provides a global framework for ICT Readiness for Business Continuity (IRBC)
. While many standards look at business continuity as a whole, ISO 27031 zooms in specifically on the technology—ensuring that your ICT services are resilient enough to support critical business functions during disruptions. Key takeaway:
It isn't just about disaster recovery; it's about "readiness"—the ability to prevent, predict, and manage ICT incidents before they cause a total shutdown. Why ISO 27031 Matters Bridge the Gap:
It bridges the gap between classic business continuity (BCM) and technical IT security. Beyond Disaster Recovery:
While disaster recovery focuses on "getting back up," ISO 27031 focuses on staying up and minimizing the recovery time (RTO) and data loss (RPO). Standardized Performance:
It allows organizations to measure their readiness in a consistent, recognized way. ISO 27031 vs. ISO 22301: What’s the Difference?
It’s common to confuse these two, but they serve different roles in your resilience ecosystem: ISO/IEC 27031:2011 - Information technology
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.
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.
ISO/IEC 27031:2011 - Information technology — Security techniques The standard formalizes a six-step loop for ICT
ISO/IEC 27031:2011 is the international standard that provides a framework for
Information and Communication Technology (ICT) Readiness for Business Continuity (IRBC)
. It ensures that an organization’s IT infrastructure and services can support business operations during unexpected disruptions. Purpose and Scope The standard bridges the gap between general Business Continuity Management (BCM) and specific IT Disaster Recovery . It focuses on:
Developing strategies to ensure ICT services are resilient and recoverable.
Aligning IT recovery objectives (RTO and RPO) with overall business requirements.
Providing a consistent methodology for planning, implementing, and monitoring ICT readiness. Core Principles of ISO 27031 The standard follows the Plan-Do-Check-Act (PDCA) cycle to build a sustainable readiness program:
: Establish the IRBC policy, objectives, and processes relevant to managing risk and improving ICT readiness.
: Implement and operate the IRBC policy, controls, processes, and procedures.
: Assess and measure process performance against IRBC policy and objectives, reporting results to management.
: Take corrective and preventive actions, based on the results of the internal audit and management review, to achieve continual improvement. Key Components for Implementation
To comply with ISO 27031, an organization must address six main categories: Skills and Knowledge
: Ensuring personnel have the training to handle emergency ICT responses. Facilities
: Securing data centers and backup sites against physical threats. Technology
: Implementing redundant systems, data replication, and failover mechanisms.
: Protecting the integrity and availability of critical information. : Establishing clear failover and failback procedures.
: Managing third-party dependencies and ensuring vendors meet the same readiness standards. ISO 27031 vs. ISO 22301

of the specific documentation required for an ISO 27031 audit?
In the dimly lit server room of OmniTech Solutions, the hum of cooling fans felt like a funeral dirge. Elias, the Chief Information Security Officer, stared at the jagged line on his monitor—a heartbeat that had flatlined. A massive ransomware attack had just crippled their primary data center, and the backup systems were unresponsive.
"Check the physical vault," Elias commanded, his voice tight.
Minutes later, a junior tech returned with a weathered, blue-bound folder. On the cover, in stark white lettering, read: ISO/IEC 27031: Guidelines for Information and Communication Technology Readiness for Business Continuity.
While the rest of the executive team scrambled in panic, Elias opened the "standard" that had been his obsession for the last year. Most saw it as a dry PDF of regulations; Elias saw it as a survival manual. The Readiness Assessment
The story of their recovery didn't start that night; it started six months prior during the ICT Readiness for Business Continuity (IRBC) audit. Elias had insisted on mapping every critical business process to its underlying technology. He had identified that their "Instant Recovery" promise was a myth without a secondary, air-gapped site.
He flipped to the section on Performance Monitoring. He had installed sensors not just for hardware failure, but for "anomalous data egress"—the very thing that had tipped them off to the breach ten minutes earlier. The Strategy in Motion Disclaimer: This report is for informational purposes only
"Phase Two," Elias muttered, pointing to a diagram in the document. Following the ISO 27031 framework, he didn't try to fix everything at once. The standard dictated a priority-based recovery.
Identify Critical Assets: They bypassed the marketing servers and the employee portal.
Establish ICT Continuity: They diverted all remaining bandwidth to the customer transaction database.
Validate: They didn't just "turn it on"; they ran the integrity checks prescribed in the standard’s technical annex. The Restoration
By 4:00 AM, while the attackers were still waiting for a ransom email, OmniTech’s core services flickered back to life. The PDF wasn't just a document; it was a blueprint for resilience. It had forced them to ask "What if?" until they had an answer for "Now what?"
As the sun rose, Elias closed the folder. The standard had transformed a potential corporate obituary into a mere footnote of operational maintenance.
The IT Security Crisis at GreenTech Inc.
GreenTech Inc. was a leading provider of innovative technology solutions for the renewable energy sector. The company had experienced rapid growth over the past few years, and its IT infrastructure had expanded to support the increasing demands of its business. However, with the growth came new security challenges, and GreenTech's IT team was struggling to keep up.
One day, the company's IT manager, Rachel, received an email from the CEO, alerting her to a potential security breach. A suspicious email had been sent to several employees, and some staff members had reported clicking on a link that seemed to be malicious. Rachel immediately called an emergency meeting with her team to assess the situation.
As they began to investigate, Rachel realized that GreenTech's current IT security measures were inadequate. The company didn't have a formal incident response plan in place, and its employees weren't trained to respond to security incidents. The IT team was in a state of panic, and Rachel knew she had to act fast.
That's when she stumbled upon the ISO 27031 standard, a guideline for information security incident management. The standard provided a framework for establishing an incident response plan, which Rachel knew was exactly what GreenTech needed.
The Journey to ISO 27031 Compliance
Rachel and her team began to study the ISO 27031 standard and realized that it provided a comprehensive framework for managing information security incidents. They understood that implementing the standard would require significant changes to their current IT security practices, but they were determined to get it done.
The team started by establishing an incident response team (IRT) and defining their roles and responsibilities. They developed a communication plan, which included procedures for reporting incidents, and created a incident response plan that outlined the steps to be taken in the event of a security breach.
The team also conducted a thorough risk assessment to identify potential security threats and vulnerabilities. They implemented measures to prevent similar incidents from occurring in the future, such as deploying additional security controls, conducting regular security awareness training for employees, and establishing a continuous monitoring program.
As they worked towards ISO 27031 compliance, Rachel's team encountered several challenges. They had to overcome resistance from some employees who were hesitant to adopt new procedures, and they had to allocate additional resources to support the implementation of the standard.
However, with persistence and dedication, the team successfully implemented the ISO 27031 standard. They conducted regular tabletop exercises to test their incident response plan and made continuous improvements to their IT security practices.
The Benefits of ISO 27031 Compliance
The efforts of Rachel and her team paid off when a real security incident occurred a few months later. A phishing attack was launched against GreenTech, but this time, the company's incident response team was ready. They quickly detected the attack, contained the damage, and communicated effectively with employees and stakeholders.
The incident response plan worked seamlessly, and the company's IT systems were restored quickly. The CEO was impressed with the team's response, and the company's reputation was protected.
The benefits of ISO 27031 compliance were clear:
GreenTech Inc. had successfully implemented the ISO 27031 standard, and it had become a model for other organizations in the industry.
