Answer(s): D
When updating a risk register with the results of an IT risk assessment, the risk practitioner should log the known risk scenarios, because they are the risk scenarios that have been identified and assessed in the IT risk assessment process. The risk register should document and track the known risk scenarios, their characteristics, their status, and their responses. The other options are not the ones that should be logged, because:Option A: High impact scenarios are the risk scenarios that have a high potential impact on the business objectives and processes, but they are not the only ones that should be logged. The risk register should include all the known risk scenarios, regardless of their impact level. Option B: High likelihood scenarios are the risk scenarios that have a high probability of occurrence, but they are not the only ones that should be logged. The risk register should include all the known risk scenarios, regardless of their likelihood level. Option C: Treated risk scenarios are the risk scenarios that have been addressed by the risk response actions, but they are not the only ones that should be logged. The risk register shouldinclude all the known risk scenarios, regardless of their treatment status. References = Risk and Information Systems Control Study Manual, 7th Edition, ISACA, 2020, p. 108.
The BEST way to obtain senior management support for investment in a control implementation would be to articulate the reduction in:
Answer(s): B
Residual risk is the risk that remains after applying risk responses, such as avoidance, mitigation, transfer, or acceptance. It represents the level of exposure that the organisation is willing to tolerate or assume. Residual risk should be aligned with the organisation's risk appetite and risk tolerance, which are determined by senior management. Therefore, the best way to obtain senior management support for investment in a control implementation would be to articulate the reduction in residual risk that the control would achieve. This would demonstrate how the control would help the organisation meet its riskobjectives and reduce the likelihood or impact of adverse events.

Who should be responsible for implementing and maintaining security controls?
The data custodian is the person who is responsible for implementing and maintaining security controls to protect the data entrusted to them by the data owner. The data custodian is typically a system administrator or a security systems administrator who has the technical skills and access rights to manage the security systems and processes that safeguard the data. The data custodian's responsibilities include, but are not limited to: Installing, configuring, and updating security systems such as firewalls, anti-virus software, encryption tools, etc. Monitoring network trafficand system logs to detect and respond to security incidents. Conducting regular security assessments and audits to ensure compliance with security policies and standards. Implementing backup and recovery procedures to ensure data availability and integrity. The data custodian works under the direction and guidance of the data owner, who is the person who has the authority and accountability for the data and its use. The data owner defines the data classification, the data retention period, and the data access rights and privileges. The data owner also approves any changes to the security controls or the data itself. The data owner is typically a senior manager or a business unit leader who has the business knowledge and responsibility for the data.

An enterprise has taken delivery of software patches that address vulnerabilities in its core business software. Prior to implementation, which of the following is the MOST important task to be performed?
Answer(s): A
Assessing the impact of applying the patches on the production environment is the most important task to be performed prior to implementation, because it helps to identify and mitigate any potential risks or issues that may arise from the patching process. Patching is a process ofapplying updates or fixes to software or hardware to address vulnerabilities, bugs, or performance issues. Patching is essential for maintaining the security and functionality of IT systems, but it also introduces the risk of introducing new problems or breaking existing features. Therefore, before applying patches, the organization should assess the impact of the patches on the production environment, such as compatibility, performance, availability, functionality, and security. Surveying other enterprises regarding their experiences with applying these patches, seeking information from the software vendor to enable effective application of the patches, and determining in advance an off-peak period to apply the patches are all helpful tasks to be performed prior to implementation, but they are not the most important task, as they do not directly address the impact of the patches on the production environment.

Numerous media reports indicate a recently discovered technical vulnerability is being actively exploited. Which of the following would be the BEST response to this scenario?
Answer(s): C
A technical vulnerability is a weakness or flaw in the design or implementation of an information system or resource that can be exploited or compromised by a threat or source of harm that may affect the organization's objectives or operations. A technical vulnerability may be caused byvarious factors, such as human error, system failure, process inefficiency,resource limitation, etc.A vulnerability assessment is a process of identifying and evaluating the technical vulnerabilities that exist or may arise in the organization's information systems or resources, and determining their severity and impact. A vulnerability assessment can help the organization to assess and prioritize the risks, and to design and implement appropriate controls or countermeasures to mitigate or prevent the risks. The best response to the scenario of a recently discovered technical vulnerability being actively exploited is to conduct a vulnerability assessment, because it can help the organization to address the following questions:What is the nature and extent of the technical vulnerability, and how does it affect the functionality or security of the information system or resource? How is the technical vulnerability being exploited or compromised, and by whom or what? What are the potential consequences or impacts of the exploitation or compromise of the technical vulnerability for the organization and its stakeholders? How can the technical vulnerability be detected and reported, and what are the available or feasible options or solutions to address or correct it? Conducting a vulnerability assessment can help the organization to improve and optimize the information system or resource quality and performance, and to reduce or eliminate the technicalvulnerability. It can also help the organization to align the information system or resource with the organization's objectives and requirements, and to comply with the organization's policies and standards.The other options are not the best responses to the scenario of a recently discovered technical vulnerability being actively exploited, because they do not address the main purpose and benefit of conducting a vulnerability assessment, which is to identify and evaluate the technical vulnerability, and to determine its severity and impact. Assessing the vulnerability management process is a process of evaluating and verifying the adequacy and effectiveness of the process that is used to identify, analyze, evaluate, and communicate the technical vulnerabilities, and to align them with the organization's objectives and requirements. Assessing the vulnerability management process can help the organization to improve and optimize the process, and to reduce or eliminate the gaps or weaknesses in the process, but it is not the best response to the scenario, because it does not indicate the nature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.Conducting a control self-assessment is a process of evaluating and verifying the adequacy and effectiveness of the controls that are intended to ensure the confidentiality, integrity, availability, and reliability of the information systems and resources, using the input and feedback from the individuals or groups that are involved or responsible for the information systems activities or functions. Conducting a control self-assessment can help the organization to identify and document the control deficiencies, and to align them with the organization's objectives and requirements, but it is not the best response to the scenario, because it does not indicate thenature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.Reassessing the inherent risk of the target is a process of reevaluating and recalculating the amount and type of risk that exists in the absence of any controls, and that is inherent to the nature or characteristics of the target, which is the information system or resource that is affected by the technical vulnerability. Reassessing the inherent risk of the target can help the organization to understand and document the risk exposure or level, and to align it with the organization's risk appetite and tolerance, but it is not the best response to the scenario, because it does not indicate the nature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.
