Focuses specifically on the micro-level technical infrastructure. It provides the technical backbone required to fulfill the broader promises made in ISO 22301.

Focuses on protecting the confidentiality, integrity, and availability of data during day-to-day operations.

It is common to confuse ISO 27031 with ISO 22301. However, they serve different purposes and operate at different levels of an organization.

The standard is not just for risk professionals; it is for leaders, IT managers, finance directors, and project leads. As Jason Brown, Chair of ISO/TC 262 noted, the revised standard focuses on the integration with the organization and the role of leaders and their responsibility, placing risk management squarely in the center of business strategy.

Information and Communication Technology (ICT) is the backbone of modern organizational operations. When IT systems fail, business stops. To mitigate this risk, the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) developed . This standard provides a definitive framework for preparing an organization's digital infrastructure to withstand, adapt to, and recover from disruptive events.

Modern IT environments depend heavily on third-party ecosystems, including cloud providers (AWS, Azure, GCP), SaaS vendors, and telecommunications companies. ISO 27031 requires analyzing supply chain dependencies, auditing vendor Service Level Agreements (SLAs), and verifying that critical suppliers have verified readiness plans of their own.

Crucially, this process highlights that risk is not just a threat. According to the official definition in ISO 31000:2018, risk is the “effect of uncertainty on objectives,” and that effect can be positive (an opportunity) or negative (a threat). Managing opportunities is as important as preventing losses.

Track whether automated backup schedules, data replication lag, and system alerts remain within parameters that support the target RPO.

drills down specifically into the ICT component demanded by ISO 22301. If ISO 22301 dictates that a financial firm must be able to process payments within two hours of a disaster, ISO 27031 provides the explicit technical strategy to ensure the underlying payment servers and databases achieve that goal.
