Introduction to Cyber Resilience
The contours of business disruption are changing, and it can start with a ransomware incident, an identity compromise, a supplier outage, or a prolonged cloud failure in one unit, then spread across connected systems.
Disruption can simultaneously affect operations, customer access, compliance, and supplier relations, making cyber resilience the backbone of business continuity.
Business Continuity and Risk Management
Business continuity is also a risk management issue, depending on how well an organization understands its critical processes, information dependencies, supplier exposure, cloud reliance, risk appetite, recovery priorities, and ability to operate when systems or data cannot be fully trusted.
The ISF Standard of Good Practice (SOGP) 2026 is an information security framework that covers this shift, connecting business continuity with governance, information risk, system resilience, security incident management, and testing.
Continuity Starts with Governance
When a security incident occurs, all functions have to work together, with decision rights, escalation paths, risk appetite, and recovery priorities becoming the foundation of governance.
The board must understand the incident's impact on revenue, operations, service delivery, and reputation, while security teams contain the spread of the incident, IT restores systems, and communications shares updates with customers and stakeholders.
Minimum Viable Business
A minimum viable business identifies the business-critical processes, information assets, people, suppliers, and infrastructure that must remain available for an organization to operate despite facing a disruptive incident.
Organizations must focus on specifics, mapping every dependency to ensure continuity in practice, such as a payment process depending on identity and access management, fraud monitoring, customer support, and cloud infrastructure.
System Resilience
System backup, restoration timelines, SLAs, capacity planning, and change management are the building blocks of business continuity, but should be seen as business resilience issues rather than just technical ones.
Continuity becomes an unfulfilled promise if critical systems cannot be restarted within agreed-upon timeframes, and alternatives should be in place for critical business infrastructure and applications.
Convergence of Incident Response and Business Continuity
A sophisticated threat landscape demands a blend of incident response and business continuity, with containment, investigation, legal assessment, customer communication, operational workarounds, supplier coordination, and system recovery happening simultaneously and seamlessly.
Continuity cannot wait for the security incident to finish, requiring a framework that brings together various disciplines to respond in accordance with a shared response structure.
Supplier and Cloud Dependencies
An organization's processes depend on a diverse supply chain, and if even one fails, continuity can be affected immediately, making supplier and cloud dependencies integral to continuity planning.
Contracts with external vendors should outline realistic expectations regarding resilience and security, aligned with the continuity and risk management framework, with continuous assessment and monitoring ensuring suppliers meet expectations.
Realizing Resilience with Testing
Testing should include all factors that can contribute to a loss of business continuity, such as ransomware, prolonged cloud outages, supplier disruptions, identity compromises, data integrity uncertainty, and customer-facing service disruptions.
The emphasis should be on testing crisis management capabilities, technical infrastructure resilience, and operational ability to resume critical processes within the predetermined timeframe.
Closing Thoughts
Business continuity is about the business holding up when the odds are stacked against it, requiring an actionable plan that keeps operations running when systems fail, data cannot be trusted, and suppliers become chokepoints.
Cyber resilience and risk management are front and center of continuity planning and must be treated as such, according to Steve Durbin, Chief Executive of the Information Security Forum.
