Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	The cybersecurity governance and programme are defined in a charter approved by executive management, which is anchored in a risk-based approach based on industry standards to balance the level of cybersecurity against the risks to Novo Nordisk. At Novo Nordisk, cybersecurity risk management is an integral part of our enterprise risk management framework defined in our information security framework. The framework aligns with industry best practice covering IT infrastructure, IT systems, and third-party service providers, and includes steps for identifying and assessing the severity of a cybersecurity threat, evaluating the potential business impact, implementing countermeasures and mitigation strategies, and informing executive management of material cybersecurity threats and incidents. Risks are consolidated across business areas and integrated into the enterprise risk management framework, where the likelihood and impact of cybersecurity risk scenarios are evaluated for risk treatment by executive management and reported to the Board of Directors. The cybersecurity risk management programme is validated through peer-benchmarked maturity assessments, external technical assessments of the core infrastructure, key applications and operational processes, as well as group internal audit evaluations of the cross-organisational controls implementation.
