The best control to help reduce the risk of fraudulent internal transactions in several business applications is the segregation of duties. Segregation of duties is the principle of dividing the roles and responsibilities of different individuals or groups involved in a business process or an IT service, so that no one person or group has complete control over the entire process or service. Segregation of duties can help to prevent or detect fraud, errors, conflicts of interest, or misuse of resources, by ensuring that there are checks and balances, and that there is adequate oversight and accountability. Segregation of duties can also help to reduce the risk of collusion, compromise, or coercion among the internal staff, by limiting their access and authority to the business applications and data. Periodic user privileges review, log monitoring, and periodic internal audits are also useful controls, but they are not as effective as segregation of duties, as they are reactive and detective measures, rather than proactive and preventive measures.

Detailed Explanation:When likelihood is unknown, range-based estimates from subject-matter experts provideinformed and realistic insights into potential risk exposure. This approach helps approximate the inherent risk based on experience and expertise, supporting effective decision-making.

The best course of action when a recent regulatory requirement has the potential to affect an organization's use of a third party to supply outsourced business services is to conduct a gap analysis, as it involves comparing the current and desired states of compliance, and identifying any gaps or discrepancies that need to be addressed. Terminating the outsourcing agreement, identifying compensating controls, and transferring risk to the third party are not the best courses of action, as they may not be feasible, effective, or appropriate, respectively, and may require the prior knowledge of the compliance gaps and risks.

An effective risk management program is a systematic and consistent process of identifying, analyzing, evaluating, treating, monitoring, and communicating risks that may affect the achievement of the organization' s objectives12.
The best indication of an effective risk management program is that the residual risk, which is the risk remaining after risk treatment, is within the organizational risk appetite, which is the amount and type of risk that the organization is willing to accept in pursuit of its objectives12.
This indicates that the organization has successfully implemented appropriate risk responses that align with its risk strategy and criteria, and that the organization is able to balance the potential benefits and costs of taking risks12.
The other options are not the best indication, but rather components or outcomes of an effective risk management program. For example:
Risk action plans are approved by senior management is an outcome of an effective risk management program that demonstrates the commitment and accountability of the leadership for risk management12.
Mitigating controls are designed and implemented is a component of an effective risk management program that involves reducing the likelihood or impact of a risk event12.
Risk is recorded and tracked in the risk register is a component of an effective risk management program that involves documenting and updating the risk information and status12. References =

Granting remote access to a system containing sensitive data to an overseas third party poses various risks to the organization, such as data breaches, unauthorized access, data loss, compliance violations, or reputational damage. The greatest concern to management when granting remote access to a third party is the lack of monitoring over vendor activities, meaning that the organization may not be able to control or verify how the third party is accessing, using, storing, or transferring the sensitive data. The lack of monitoring over vendor activities can increase the risk exposure and uncertainty of the organization, as well as reduce the accountability and transparency of the third party. Therefore, the organization should implement appropriate measures to monitor and audit the vendor activities, such as logging, reporting, reviewing, or testing, and to ensure that the vendor complies with the contractual obligations and the security policies and standards of the organization.
