Abstract: In the face of a deteriorating cyber threat landscape, it has never been more important for entities to prepare for a cyber incident. This paper presents the cyber incident response capability development life cycle, a cumulative and iterative approach to considering cyber threats from multiple dimensions to identify capability gaps and providing the opportunity for focused skill uplift. The life cycle addresses all aspects of cyber incidents and provides innovative approaches to accommodating the needs of all stakeholders across all roles in an entity, from simplified exercises to complex simulated events. Exercising incident response plans and the associated playbooks is a feature of all standards and frameworks, and consistently recommended through government and regulatory advice.
