An IT risk register is a document that records the identified IT risks, their analysis, and their responses. It is a useful tool for managing and communicating the IT risks throughout the project or the organization. The most important factor for maintaining the effectiveness of an IT risk register is to perform regular reviews and updates to the register, meaning that the riskpractitioner should periodically check and revise the riskregister to reflect the changes in the IT risk environment, the project status, or the organization’s objectives. Performing regular reviews and updates to the register can help to ensure that the risk register is accurate, complete, and current, and that it provides relevant and reliable information for the risk management decision making and actions. Performing regular reviews and updates to the register can also help to identify any new or emerging IT risks, as well as to monitor and report on the IT risk performance and improvement. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.2.1, p. 106-107
