The risk register element that is most likely to be updated if the attack surface or exposure of an asset is reduced is the likelihood rating, as this reflects the probability or frequency of a risk event occurring. The attack surface or exposure of an asset is the measure of the extent and accessibility of the asset to potential threats or attackers. If the attack surface or exposure of an asset is reduced, the likelihood of the asset being compromised or damaged by a risk event is also reduced. Therefore, the likelihood rating of the risk should be updated accordingly. The other options are not the risk register elements that are most likely to be updated if the attack surface or exposure of an asset is reduced, although they may be affected or influenced by it.
Control effectiveness is the measure of how well the risk controls reduce the risk level or achieve the control objectives. Assessment approach is the method or technique used to identify, analyze, and evaluate the risks.
Impact rating is the measure of the magnitude or severity of the consequences of a risk event on the asset or the organization. References = Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Identification, page 54.

The global organization has adopted risk acceptance as the risk response with regard to privacy requirements, as it has decided to continue with the implementation of the application that does not address all privacy requirements across multiple jurisdictions, and bear the potential consequences of noncompliance. Risk avoidance, risk transfer, and risk mitigation are not the risk responses adopted by the organization, as they would involve avoiding, sharing, or reducing the risk of noncompliance with privacy requirements, respectively.

Multi-factor authentication (MFA)significantly enhances transaction integrity by ensuring that users are who they claim to be. It is a practical, widely adopted control to prevent unauthorized access.

The organization's process owner should own the risk of exposing the payroll data due to a control weakness at the third party, because the process owner is the person who is responsible for the business process that generates, uses, or transfers the payroll data. The process owner should also ensure that the third party complies with the contractual obligations and service level agreements that define the expected performance and security standards of the payroll data processing. The other options are not the correct answers, because they are not the primary owners of the risk, although they may also be involved in the risk management process. The third party's IT operations manager, the third party's chief risk officer (CRO), and the organization's risk practitioner are examples of secondary owners or stakeholders of the risk, who may provide support, guidance, or oversight to the risk owner, but they are not accountable for the risk or the risk response strategy.

When adopting new technology, the first step is toreassess risks and control effectivenessbecause the technology may introduce new vulnerabilities or alter existing risk profiles.
CRISC guidance:
"Significant changes to business or technology environments should trigger a re-evaluation of existing risk scenarios and control effectiveness to identify new or residual risk." Updating appetite or seeking support follows after reassessment.
Hence,Dis correct.
