A cloud access security broker (CASB) solution is the best way to enforce access control for an organization that uses multiple cloud technologies, as it provides a centralized and consistent platform to manage and monitor the access to various cloud services and applications. A CASB solution can help to implement and enforce the enterprise's access policies and standards, as well as to detect and prevent unauthorized or malicious access attempts. Senior management support of cloud adoption strategies, creation of a cloud access risk management policy, and expansion of security information and event management (SIEM) to cloud services are not the best ways to enforce access control for an organization that uses multiple cloud technologies, as they do not provide the technical capabilities or tools to manage and monitor the access to various cloud services and applications.

A risk register is a document that is used as a risk management tool to identify and track risks that may affect a project or an organization1. A risk register should be updated regularly to reflect the current status and changes of the risks, as well as the actions taken to mitigate or resolve them2. The most comprehensive information for updating a risk register would come from the results of the latest risk assessment, which is a process that involves identifying, analyzing, and evaluating the risks and their potential impacts3. A risk assessment provides a detailed and systematic overview of the risks, theirsources, causes, likelihood, severity, and consequences, as well as the existing and planned controls andresponses4. A risk assessment also helps to prioritize the risks based on their level of exposure and urgency, and to align them with the organization's risk appetite and tolerance5. Therefore, the results of the latest risk assessment would provide the most relevant and complete information for updating a risk register and ensuring that it reflects the current risk profile and situation of the project or the organization. Results of a risk forecasting analysis are not the most comprehensive information for updating a risk register, as they do not provide a complete picture of the risks and their impacts. A risk forecasting analysis is a technique that uses historical data, trends, and scenarios to estimate the potential outcomes and impacts of future events that may affect the organization's objectives and performance6. A risk forecasting analysis can help to anticipate and prepare for the risks, but it does not provide specific information on the sources, causes, likelihood, severity, and consequences of the risks, nor the existing and planned controls and responses. A review ofcompliance regulations is not the most comprehensive information for updating a risk register, as it does not cover all the aspects and dimensions of risk management. A review of compliance regulations is a process that involves checking and verifying that the organization's activities, processes, and systems are in accordance with the applicable laws, rules, and standards7. A review of compliance regulations can help to identify and mitigate the risks related to legal or regulatory violations, but it does not provide specific information on the other types and sources of risks, such as operational, strategic, financial, or reputational risks, nor the existing and planned controls and responses.
Findings of the most recent audit are not the most comprehensive information for updating a risk register, as they do not provide a current and holistic view of the risks and their impacts. An audit is an independent examination and evaluation of the organization's activities, processes, and systems, to provide assurance and advice on their adequacy and effectiveness. An audit can help to identify and report the issues or gaps in the organization's risk management, but it does not provide specific information on the current status and changes of the risks, nor the existing and planned controls and responses.

According to the CRISC Review Manual (Digital Version), reviewing the business impact analysis (BIA) will best help an organization select a recovery strategy for critical systems, as it provides an assessment of the potential impact and consequences of a disruption to the organization's critical business functions and processes. Reviewing the BIA helps to:
Identify and prioritize the critical systems and their dependencies that support the critical business functions and processes Estimate the maximum tolerable downtime (MTD) and the recovery time objective (RTO) for each critical system Evaluate the feasibility and cost-effectiveness of various recovery strategies and options for each critical system Select the most appropriate recovery strategy and option for each critical system based on the organization's objectives and requirements Develop and implement the recovery plan and procedures for each critical system References = CRISC Review Manual (Digital Version), Chapter 3: IT Risk Response, Section 3.3: Risk Response Options, pp. 174-1751

A risk register is a tool that records and tracks the identified risks, their causes, impacts, probabilities, responses, and owners. It is a living document that should be updated regularly to reflect the changes in therisk environment and the status of the risk responses12. The best way to improve a risk register is to ensure that it is updated based upon significant events, such as:
New risks are identified or existing risks are eliminated
Risk probabilities or impacts change due to internal or external factors Risk responses are implemented or modified Risk owners or stakeholders change Risk incidents or issues occur Risk thresholds or appetite change Risk reporting or communication requirements change Updating the risk register based upon significant events can help to:
Maintain the accuracy and relevance of the risk information
Enhance the risk awareness and accountability of the risk owners and stakeholders Support the risk monitoring and reporting activities Facilitate the risk evaluation and decision-making processes Improve the risk management performance and maturity References = Risk Register - Project Management Knowledge How to Create a Risk Register: A Step-by-Step Guide - ProjectManager.com

Accepting risk is the only risk response strategy that could be applied to both positive and negative risk that has been identified. Accepting risk means taking no action to change the likelihood or impact of the risk, but being prepared to deal with the consequences if the risk occurs. Accepting risk is usually chosen when the risk is low, unavoidable, or outweighed by the benefits. For positive risks, accepting risk means taking advantage of the opportunities if they arise. For negative risks, accepting risk means setting aside contingency reserves or plans to cope with the threats. The other risk response strategies are specific to either positive or negative risks. Transfer, exploit, and mitigate are strategies for negative risks, while share, enhance, and avoid are strategies for positive risks.
