The best evidence of an effective internal control environment is the independent audit results. Independent audit results are the outcomes or findings of an external or independent party that evaluates the design, implementation, and operation of the internal controls. Independent audit results can provide an objective, reliable, and consistent assessment of the internal control environment, and identify the strengths, weaknesses, gaps, or issues of the internal controls. Independent audit results can also provide assurance, recommendations, or improvement opportunities for the internal control environment. The other options are not as good as independent audit results, as they are related to the inputs, processes, or outputs of the internal control environment, not the evaluation or verification of the internal control environment.

The number of projects going live without a security review is the best key control indicator (KCI) to indicate whether security requirements are identified and managed throughout a project life cycle, because it measures the compliance and effectiveness of the security review process. A security review is a process that ensures that the security requirements are defined, implemented, tested, and verified for each project, and that any security risks or issues are identified and resolved before the project is deployed. The number of projects going live without a security review should be minimized or eliminated, as it indicates a failure or weakness of the security review process. The other options are not the best KCIs, because they do not directly measure the identification and management of security requirements. The number of employees completing project-specific security training, the number of security projects started in core departments, and the number of security-related status reports submitted by project managers are examples of input or output indicators that measure the activities or results of the project, but not the security requirements.

The best indicator to senior management that IT processes are improving is the changes in the position in the maturity model. A maturity model is a framework that defines the levels of capability and performance of a process, such as IT processes, based on the criteria such as governance, management, control, measurement, and improvement. A maturity model can help to assess the current state and the desired state of the IT processes, and to identify the gaps, strengths, and opportunities for improvement. A maturity model can also help to communicate the progress and the value of the IT processes to the senior management, and to support the strategic alignment and integration of the IT processes with the business objectives. Changes in the position in the maturity model indicate that the IT processes are improving, as they show that the IT processes are moving from a lower level to a higher level of maturity, and that they are achieving higher standards of quality, efficiency, and effectiveness. Changes in the number of intrusions detected, changes in the number of security exceptions, and changes to the structure of the risk register are not as good as changes in the position in the maturity model, as they do not provide a comprehensive and consistent measure of the IT processes improvement, and they may not reflect the actual impact and performance of the IT processes.

The first course of action for a risk practitioner when an organization plans to adopt a cloud computing strategy is to perform a controls assessment. This means evaluating the existing controls in the organization and the cloud service provider, and identifying the gaps and weaknesses that need to be addressed. A controls assessment can help to determine the level of risk exposure and the suitability of the cloud service model and provider for the organization's needs and objectives. It can also help to establish the baseline for monitoring and reporting on the cloud service performance and compliance.

According to Wikipedia1, a maturity model is a framework for measuring an organization's maturity, or that of a business function within an organization, with maturity being defined as a measurement of the ability of an organization for continuous improvement in a particular discipline. A maturity model will best indicate the effectiveness and efficiency of an organization or a business function, as it helps to evaluate how well they achieve their intended objectives with minimum resources, time, and cost. A maturity model also helps to identify and prioritize the areas and opportunities for improvement, and to establish and communicate the standards and best practices for the discipline.
