The primary reason for a risk practitioner to report changes and trends in the IT risk profile to senior management is to ensure that IT risk is managed within acceptable limits, because it helps to inform and advise the senior management on the current state and direction of IT risk, and to support the risk-based decision making and prioritization. An IT risk profile is a summary of the key IT risks that an organization faces, and their implications for the organization's objectives and strategy. An IT risk profile may change or evolve over time, due to factors such as newtechnologies, business initiatives, or external events. Reporting changes and trends in the IT risk profile to senior management is the primary reason, as it helps to ensure that the senior management is aware of and prepared for the IT risk challenges and opportunities, and that the IT risk is managed within the acceptable limits defined by the organization's risk appetite and tolerance. To ensure risk owners understand their responsibilities, to ensure the organization complies with legal requirements, and to ensure the IT risk awareness program is effective are all possible reasons for reporting changes and trends in the IT risk profile, but they are not the primary reason, as they are not directly related to the management of IT risk within acceptable limits.
