Explanation:
The main objective of risk management is to reduce risk to a level that the organization or company will accept, as the risk can never be completely eliminated.
Incorrect Answers:
A, B: There are no such concepts existing in manipulating risk level.
D: Risk mitigation involves identification, planning, and conduct of actions for reducing risk. Because the elimination of all risk is usually impractical or close to impossible, it is aimed at reducing risk to an acceptable level with minimal adverse impact on the organization's resources and mission.

The best course of action when an organization wants to reduce likelihood in order to reduce a risk level is to implement preventive measures. Likelihood is the probability or chance of a risk occurring, and risk level is the combination of likelihood and impact of a risk. Preventive measures are controls that are designed to prevent or deter the occurrence of a risk, such as policies, standards, procedures, guidelines, etc. Implementing preventive measures is the best course of action, because it helps to reduce the likelihood of a risk, and consequently, the risk level. Implementing preventive measures also helps to protect and enhance the organization's objectives, performance, and improvement. The other options are not the best course of action, although they may be related to the risk management process. Monitoring risk controls, implementing detective controls, and transferring the risk are all activities that can help to manage or mitigate the risks, but they do not necessarily reduce the likelihood or the risk level.

Risk assessments are most effective when performed at each stage of the system development life cycle (SDLC). The SDLC is a framework that defines the phases and activities of developing, implementing, and maintaining a system. The SDLC typically consists of the following stages: initiation, planning, analysis, design, development, testing, implementation, and maintenance. Performing risk assessments at each stage of the SDLC helps to identify, analyze, and evaluate the risks that could affect the system objectives, requirements, functionality, quality, or performance. Performing risk assessments at each stage of the SDLC also helps to select and implement the appropriate risk responses, such as avoiding, transferring, mitigating, or accepting the risks. Performing risk assessments at each stage of the SDLC also helps to monitor and report the risk status and performance, and to update and adjust the risk assessment and response as the system changes or evolves. Performing risk assessments before system development begins, at system development, or during the development of the business case are not as effective as performing risk assessments at each stage of the SDLC, as they are either too early or too late, and they do not capture the full scope and complexity of the system risks.

The most helpful factor for an information security management team when allocating resources to mitigate exposures is the risk assessment results. The risk assessment results provide a comprehensive and objective analysis of the risks facing the enterprise, including their likelihood, impact, and root causes. The risk assessment results also help to identify the gaps and weaknesses in the existing controls, and to prioritize the risks based on their severity and urgency. The risk assessment results enable the information security management team to allocate the resources in a cost-effective and risk-based manner, and to implement the most appropriate risk responses to reduce the exposures to an acceptable level.
