An IT risk register is a document that records and tracks the identified IT risks, their likelihood, impact, and mitigation strategies. It is a living document that needs to be updated regularly to reflect the current risk profile of the organization. One of the situations that would require updates to the IT risk register is the discovery of an ineffectively designed key IT control, as this would increase the likelihood or impact of the related IT risk. Management review of key risk indicators (KRIs), changes to the team responsible for maintaining the register, and completion of the latest internal audit are not reasons to update the IT risk register, as they do not affect the identified IT risks or their mitigation strategies.
