Cyber resilience is a concept that integrates business continuity, information systems security, and organizational resilience. It describes the ability to maintain intended outcomes despite facing challenging cyber events, such as cyberattacks, natural disasters, or economic downturns. The level of information security proficiency and resilience directly impacts how effectively an organization can sustain business operations with minimal to no downtime.
What is effective cyber resilience?
Effective cyber resilience must be an enterprise-wide, risk-based strategy, driven collaboratively from executives to everyone in the organization, including partners, supply chain participants, and customers. It must proactively manage risks, threats, vulnerabilities, and the effects on critical information and supporting assets.
Effective cyber resilience also involves governance, risk management, understanding data ownership, and incident management. Evaluating these aspects requires experience and judgment. Additionally, an organization must balance cyber risks against achievable opportunities and competitive advantages. It must consider whether cost-effective prevention is feasible and whether it can achieve rapid detection and correction to enhance cyber resilience in the short term. To do this, an enterprise must strike the right balance among three types of controls: preventative, detective, and corrective. These controls serve to prevent, detect, and correct incidents that threaten an organization’s cyber resilience.

Why cyber resilience is important
A cyber resilience strategy is essential for business continuity, offering benefits beyond merely enhancing an enterprise’s security posture and reducing the risk to its critical infrastructure. Cyber resilience also helps minimize financial losses and mitigate reputational damage. Additionally, achieving cyber resilience certification can instill trust in clients and customers. A cyber-resilient company can optimize value creation for its customers, enhancing its competitive advantage through effective and efficient operations.
Mitigating Financial Loss
Financial loss can erode confidence among stakeholders such as shareholders, investors, employees, and customers. According to the 2020 Cyber Resilient Organization Report, over 50% of organizations experienced a cybersecurity incident that disrupted IT and business processes. The average cost of a data breach is $4.24 million, as reported in Ponemon’s 2021 Cost of a Breach Study.
Gaining Customer Trust and Business
To attract customers and secure their business, some organizations comply with international management standards like ISO/IEC 27001 from the International Organization for Standardization. ISO/IEC 27001 provides conditions for an information security management system (ISMS) to secure assets such as employee details, financial information, intellectual property, or third-party entrusted information. In the US, companies might seek certification with the Payment Card Industry Data Security Standard (PCI-DSS), a requirement for processing payments like credit card transactions.
Increasing Competitive Advantage
Cyber resilience gives organizations a competitive edge over those without it. Enterprises that develop management systems based on best practices, such as the Information Technology Infrastructure Library (ITIL), achieve effective operations. Similarly, by developing management systems for cyber resilience, organizations enhance their operational effectiveness and deliver significant value to their customers.
What are the objectives of a framework for cyber resilience?
The National Institute of Standards and Technology (NIST) has outlined four key goals for a cyber resilience framework:
Anticipate: Cyber-resilient organizations develop a clear understanding of the types of attacks and threats most likely to harm the organization and disrupt business continuity. To address these threats, security teams may implement practices, protections, and controls such as identity and access management, vulnerability assessments, microsegmentation, penetration testing, and security awareness training.
Withstand: Cyber-resilient organizations acknowledge that not all attacks or natural disasters can be prevented. While maintaining preventive measures, IT security teams adopt programs and technologies to detect threats, quickly mitigate attacks, and effectively limit any damage.
Recover: Organizations must have the capability to restore systems and operations as swiftly as possible following an attack or outage.
Adapt: After each IT threat or challenge, security teams evaluate the response and adjust security programs and IT practices to continually enhance cyber resilience.
What are the components of cyber resilience?
Cyber resilience strategies concentrate on four key areas:
Cybersecurity: Cybersecurity policies and solutions are fundamental to a cyber resilience strategy. Security teams implement multiple layers of defenses to reduce the organization’s attack surface, and to monitor, detect, defend against, and respond to threats and intrusions.
Business Continuity: Business continuity initiatives ensure that the organization can maintain operations and that employees, customers, and partners have access to IT services, data, and systems.
Risk Management: Risk management efforts involve identifying, assessing, and controlling threats to the organization’s IT ecosystem. An effective cyber risk management program enables security teams to identify and prioritize the various layers of risk facing the organization.
Disaster Recovery: Disaster recovery encompasses the procedures, policies, and tools that organizations use to recover swiftly from outages and attacks, and to restore mission-critical functions.
What are the benefits of cyber resilience?
A superior strategy for cyber resilience enables organizations to:
Maintain Business Continuity: Even when cyberattacks succeed, a cyber-resilient organization can minimize downtime, keep business systems running, and continue delivering services to customers.
Enhance Security: Cyber resilience strategies assist security teams in quickly identifying external and internal threats, preventing costly data breaches. This involves leveraging threat intelligence about known vulnerabilities and exploits.
Increase Productivity: By ensuring IT systems remain available during threats and outages, cyber resilience strategies guarantee employees access to the data and systems they need to stay productive.
Ensure Compliance: A top-tier cyber resilience program incorporates the necessary controls to comply with various regulatory frameworks (e.g., PCI DSS v4.0), helping to avoid fines and penalties from noncompliance.
Avoid Financial Loss: By preventing threats and rapidly recovering from crises, cyber resilience strategies help organizations minimize financial losses from decreased productivity, missed business opportunities, lost data, and reputational damage.
Improve Trust: Organizations focusing on cyber resilience can build greater trust with customers, partners, vendors, and employees.
Achieve Competitive Advantage: Cyber resilience enables organizations to sidestep the high costs and distractions of crises and disasters, allowing them to seize business opportunities and maintain a competitive edge.
