The risk practitioner should update the risk scenarios in the risk register to reflect the new international regulations and their potential impact on the organization. The risk register is a tool that records and tracks the identified risks, their likelihood, impact, mitigation strategies, and status. Updating the risk register will help the risk practitioner to prioritize and manage the risks effectively, and communicate them to the relevant stakeholders.

The best indication that risk management is effective is when risk has been reduced to meet the risk appetite of the enterprise. Risk appetite is the amount and type of risk that an enterprise is willing to accept in pursuit of its objectives. Risk appetite reflects the enterprise's risk culture, strategy, and values, and provides a basis for setting risk tolerance levels and risk response strategies. Risk management is effective when it enables the enterprise to align its risk exposure with its risk appetite, and to optimize the risk-return trade- off.

The most critical factor to consider when determining an organization's risk appetite is the management culture. The management culture reflects the values, beliefs, and attitudes of the senior management and the board of directors toward risk management. The management culture influences how the organization defines, communicates, and implements its risk appetite and tolerance. Fiscal management practices, business maturity, and budget for implementing security are other factors that may affect the risk appetite, but they are not as critical as the management culture.

The best course of action for a risk practitioner when senior management is deciding whether to share confidential data with the organization's business partners is to submit a report to senior management containing the possible risk and suggested mitigation plans. A risk practitioner is a professional who is responsible for identifying, assessing, and managing the risks that could affect the organization's objectives or operations. A risk practitioner should provide senior management with the information and guidance they need to make informed and effective decisions regarding the sharing of confidential data. A risk practitioner should submit a report that outlines the possible risk scenarios, such as data loss, theft, or compromise, and their likelihood and impact. A risk practitioner should also suggest mitigation plans, such as encryption, access control, monitoring, or contractual agreements, that could reduce or transfer the risk. The other options are not as effective as submitting a report containing the possible risk and suggested mitigation plans, although they may be part of or derived from the report. Designing controls to encrypt the data to be shared, developing a project plan for classification of the data, and summarizing the data protection and privacy legislation are all activities or outcomes that could be included or referenced in the report, but they are not the best course of action for a risk practitioner.
