An IT risk assessment is a process that involves identifying, analyzing, and evaluating the IT-related risks and their potential impacts on the organization’s objectives and performance1. Identifying and communicating with stakeholders at the onset of an IT risk assessment is the process of determining and engaging the persons or entities that have an interest or influence in the IT risk management, such as the IT users, owners, managers, orproviders2. The primary benefit of identifying and communicating with stakeholders at the onset of an IT risk assessment is to define the risk assessment scope, which is theboundary or extent of the IT risk assessment, such as the IT systems, processes, or functions that are included or excluded from the assessment3. By identifying and communicating with stakeholders at the onset of an IT risk assessment, the organization can ensure that the risk assessment scope is relevant, realistic, and aligned with the organization’s strategy, vision, and mission, and that it reflects the current and emerging IT risks and their potential consequences. Identifying and communicating with stakeholders at the onset of an IT risk assessment can also help to establish and communicate the roles and responsibilities of the stakeholders, and to enforce the accountability and performance of the IT risk management. Obtaining funding support, selecting the risk assessment framework, and establishing inherent risk are not the primary benefits of identifying and communicating with stakeholders at the onset of an IT risk assessment, as they do not provide the same level of insight and relevance as defining the risk assessment scope. Obtaining funding support is the process of securing and providing the necessary funds or resources that are required to support or enable the IT risk assessment4. Obtaining funding support can enhance the quality and performance of the IT risk assessment, but it is not the primary benefit of identifying and communicating with stakeholders at the onset of an IT risk assessment, as it does not determine or influence the boundary or extent of the IT risk assessment. Selecting the risk assessment framework is the process of choosing or developing a set of principles, methods, and tools that guide and facilitate the IT risk assessment5. Selecting the risk assessment framework can improve the reliability and consistency of the IT risk assessment, but it is not the primary benefit of identifying and communicating with stakeholders at the onset of an IT risk assessment, as it does not define or affect the scope or coverage of the IT risk assessment. Establishing inherent risk is the process of assessing the level of risk that exists before any controls or mitigating factors are considered. Establishing inherent risk can help to understand and prioritize the IT risks and their impacts, but it is not the primary benefit of identifying and communicating with stakeholders at the onset of an IT risk assessment, as it doesnot specify or limit the scope or range of the IT risk assessment. References = 1: IT Risk Assessment - an overview | ScienceDirect Topics2: Stakeholder Requirements - an overview | ScienceDirect Topics3: Risk Assessment Scope - an overview | ScienceDirect Topics4: Funding Support - an overview | ScienceDirect Topics5: Risk Assessment Framework - an overview | ScienceDirect Topics : [Inherent Risk - an overview | ScienceDirect Topics] : [Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.1: Risk Identification, pp. 57-59.] : [Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.2: Risk Analysis, pp. 67-69.] : [Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.3: Risk Evaluation, pp. 77-79.] : [Risk and Information Systems Control Study Manual, Chapter 3: Risk Response, Section 3.1: RiskResponse Options, pp. 113-115.] : [Risk and Information Systems Control Study Manual, Chapter 4: Risk and Control Monitoring and Reporting, Section 4.1: Key Risk Indicators, pp. 181-185.] : [Risk and Information Systems Control Study Manual, Chapter 4: Risk and ControlMonitoring and Reporting, Section 4.2: Risk Monitoring, pp. 189-191.] : [Risk and Information Systems Control Study Manual, Chapter 5: Information Systems Control Design and Implementation, Section 5.1: Control Design, pp. 233-235.] : [Risk and Information Systems Control Study Manual, Chapter 5: Information Systems Control Design and Implementation, Section 5.2: Control Implementation, pp. 243-245.] : [Risk and Information Systems Control Study Manual, Chapter 5: Information Systems Control Design and Implementation, Section 5.3: Control Monitoring and Maintenance, pp. 251-253.]

An intrusion detection system (IDS) is a network security tool that monitors network traffic and devices for known malicious activity, suspicious activity or security policy violations1. An IDS can generate alerts when it detects any potential threats, but not all alerts are accurate or relevant. There are two types of errors that can affect the performance and reliability of an IDS: false positives and false negatives2.

A false positive is when an IDS incorrectly flags a benign or normal activity as malicious or suspicious. For example, an IDS may alert on a legitimate network scan or a harmless software update. False positives can reduce the credibility and efficiency of an IDS, as they can overwhelm the security team with unnecessary alerts, distract them from the real threats, and cause them to ignore or disable the IDS3.

A false negative is when an IDS fails to flag a malicious or suspicious activity as such. For example, an IDS may miss a stealthy or novel attack that does not match any known signatures or patterns. False negatives can compromise the security and integrity of the network, as they can allow attackers to bypass the IDS and cause damage or steal data without being detected4.

The risk practitioner should recommend to analyze the alerts to minimize the false positives, because this is the best way to improve the accuracy and usefulness of the IDS. By analyzing the alerts, the risk practitioner can:

Identify the sources and causes of the false positives, such as misconfigured or outdated IDS rules, network anomalies, or legitimate traffic that resembles malicious traffic5.

Adjust or fine-tune the IDS settings, such as the alert threshold, the sensitivity level, the detection method, or the rule base, to reduce the number of false positives without increasing the risk of false negatives.

Validate or verify the alerts with other sources of information, such as logs, network traffic analysis, or threat intelligence, to confirm or dismiss the alerts as true or false positives.

Prioritize or classify the alerts based on their severity, impact, or likelihood, to focus on the most critical or relevant alerts and avoid alert fatigue.

The other options are not the best course of action, because:

Resetting the alert threshold based on peak traffic is not a reliable or effective way to minimize the false positives, as it may also increase the risk of false negatives. The alert threshold is the level of activity or deviation that triggers an alert from the IDS. If the threshold is set too high, the IDS may miss some malicious or suspicious activity that occurs below the threshold. If the threshold is set too low, the IDS may generate too many alerts for normal or benign activity that exceeds the threshold. The optimal threshold depends on various factors, such as the network size, topology, traffic volume, and baseline. Peak traffic is not a good indicator of the optimal threshold, as it may vary depending on the time, day, or season, and it may not reflect the normal or expected network behavior.

Analyzing the traffic to minimize the false negatives is not the main issue or goal in this scenario, as the problem is the high number of alerts, not the low number of alerts. Analyzing thetraffic can help to identify the malicious or suspicious activity that the IDS may have missed, but it does not address the root cause of the false positives or improve the IDS performance. Moreover, analyzing the traffic can be time-consuming and resource-intensive, especially for large or complex networks, and it may require specialized tools or skills that the risk practitioner may not have.

Sniffing the traffic using a network analyzer is not a suitable or feasible option in this scenario, as it may violate the privacy or security policies of the network or the organization. Sniffing the traffic means capturing and inspecting the network packets that are transmitted or received by the devices on the network. A network analyzer is a tool that can perform this function and display the packet data in a readable format. However, sniffing the traffic can also expose sensitive or confidential information, such as passwords, usernames, or credit card numbers, that may be contained in the packets. Therefore, sniffing the traffic may require authorization or consent from the network owners or users, and it may be restricted or prohibited by law or regulation.

A virus transmitted on a USB thumb drive is a scenario that represents a threat, as it involves a malicious or harmful event that could compromise the confidentiality, integrity, or availability of an information system. A virus is a type of malware that can infect and damage files, programs, or devices by replicating itself and spreading to other systems or networks. A USB thumb drive is a portable storage device that can be used to transfer data between computers or devices. Avirus transmitted on a USB thumb drive can occur when a user inserts an infected USB thumb drive into a computer or device, or when a user downloads or copies an infected file from a USB thumb drive to a computer or device. A virus transmitted on a USB thumb drive can pose a serious risk to the information system, as it can corrupt or delete data, disrupt or degrade performance, steal or leak information, or allow unauthorized access or control.

The other options are not scenarios that represent a threat, but rather vulnerabilities or weaknesses that could increase the likelihood or impact of a threat. Connecting a laptop to a free, open, wireless access point (hotspot) is a vulnerability, as it exposes the laptop to potential eavesdropping, interception, or manipulation by malicious actors on the same network. Visitorsnot signing in as per policy is a vulnerability, as it creates a gap in the physical security and access control of the premises, and could allow unauthorized or malicious visitors to enter or access sensitive areas or assets. Storing corporate data in unencrypted form on a laptop is a vulnerability, as it reduces the protection and security of the data, and could enable unauthorized or malicious access, disclosure, or modification of the data in case of loss, theft, or compromise of the laptop. References = What is a Computer Virus? | McAfee, What is a USB Flash Drive? | Kingston Technology, Threats, Vulnerabilities, and Exploits – oh my!

A risk response action plan is a document that outlines the specific tasks, resources, timelines, and deliverables for the risk responses, which are the actions or strategies that are taken to address the risks that may affect the organization’s objectives, performance, or value creation12.

The most useful tool when measuring the progress of a risk response action plan is an up-to-date risk register, which is a document that records and tracks the significant risks that the organization faces, and the responses and actions that are taken to address them34.

An up-to-date risk register is the most useful tool because it provides a comprehensive and consistent view of the risk landscape, and the status and performance of the risk responses and actions34.

An up-to-date risk register is also the most useful tool because it enables the monitoring and evaluation of the risk response action plan, and the identification and communication of any issues or gaps that need to be resolved or improved34.

The other options are not the most useful tools, but rather possible metrics or indicators that may be used to measure the progress of a risk response action plan. For example:

Percentage of mitigated risk scenarios is a metric that measures the proportion of risk scenarios that have been reduced or eliminated by the risk responses and actions56. However, this metric is not the most useful tool because it does not provide a comprehensive and consistent view of the risk landscape, and it may not capture the residual or emerging risks that may arise after the risk responses and actions56.

Annual loss expectancy (ALE) changes is a metric that measures the difference between the expected annual losses before and after the risk responses and actions78. However, this metric is not the most useful tool because it does not provide a comprehensive and consistent view of the risk landscape, and it may not reflect the qualitative or intangible impacts of the risks or the risk responses and actions78.

Resource expenditure against budget is a metric that measures the amount of resources and funds that have been spent or allocated for the risk responses and actions, compared to the planned or estimated budget . However, this metric is not the most useful tool because it does not provide acomprehensive and consistent view of the risk landscape, and it may not indicate the effectiveness or efficiency of the risk responses and actions . References =

Unvalidated AI outputs pose considerable integrity and operational risks, potentially leading to erroneous decisions or compliance lapses. ISACA CRISC guidance underscores that ensuring results validity is a highest-priority control for new technologies such as AI.

 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 thebusiness 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. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 217.

Key risk indicators (KRIs) are metrics that help organizations monitor and assess potential risks that may impact their operations, financial health, or overall performance1. KRIs should have certain characteristics that make them effective for risk monitoring, such as:

Ability to measure the right thing (e.g., supports the decisions that need to be made)

Quantifiable (e.g., damages in dollars of profit loss)

Capability to be measured precisely and accurately

Relevant (measuring the right thing associated with decisions)2

Among the four options given, only option C (sensitivity to changes in risk levels) best enables effective risk monitoring. This is because KRIs should be able to capture the changes in risk levels over time and alert organizations to emerging or escalating risks3. A high sensitivity to changes in risk levels indicates that theKRI is responsive and timely, and can help organizations take preventive or corrective actions before the risks become too severe.

The greatest concern associated with the transmission of healthcare data across the internet is unencrypted data, as this exposes the data to unauthorized access, interception, modification, or disclosure, which may compromise the confidentiality, integrity, and availability of the data. Healthcare data is sensitive and personal information that may include medical records, diagnoses, treatments, prescriptions, insurance claims, and biometric data. Healthcare data is subject to various legal and regulatory requirements, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States, that mandate the protection and privacy of the data. Encryption is a method of transforming the data into an unreadable format that can only be accessed or restored by authorized parties who have the decryption key. Encryption helps to prevent or reduce the risk of data breaches, identity theft, fraud, or other malicious attacks. The other options are not the greatest concerns associated with the transmission of healthcare dataacross the internet, although they may pose some challenges or issues. Lack of redundant circuits is a concern for the reliability and continuity of the data transmission, but it does notaffect the security or privacy of the data. Low bandwidth connections is a concern for the speed andefficiency of the data transmission, but it does not affect the security or privacy of the data. Data integrity is a concern for the accuracy and completeness of the data, but it does not necessarily depend on the encryption of the data. References = Risk and Information Systems Control Study Manual, Chapter 4: Risk Response, page 156.

 Inaccurate risk ratings would most likely cause management to unknowingly accept excessive risk, as they may not reflect the true level of risk exposure and impact, and may lead to inappropriate risk responses or decisions. Satisfactory audit results, risk tolerance being set too low, and lack of preventive controls are not the most likely causes, as they may indicate a different risk management issue, such as over-reliance on audit assurance, misalignment of risk tolerance and appetite, or insufficient risk mitigation, respectively. References = CRISC Review Manual, 7th Edition, page 109.

The MOST important consideration when developing IT risk scenarios is the potential threats and vulnerabilities that may have an impact on the business, because they are the key elements of a risk scenario that describe the sources and causes of the risk, and the potential consequences and impacts of the risk on the business objectives and processes. The other options are not as important as the potential threats and vulnerabilities, because:

Option A: The impact of controls on the efficiency of the business in delivering services is a secondary consideration that may affect the cost-benefit analysis of the risk response, but it does not directly affect the identification and assessment of the risk scenario.

Option B: Linkage of identified risk scenarios with enterprise risk management is a good practice that ensures the alignment and integration of the IT risk management with the overall enterprise risk management, but it does not directly affect the identification and assessment of the risk scenario.

Option D: Results of network vulnerability scanning and penetration testing are useful sources of information that may reveal some of the threats and vulnerabilities in the IT environment, but they are not the only or the most important consideration when developing IT risk scenarios, as they may not cover all the aspects and dimensions of the risk. References = Risk and Information Systems Control Study Manual, 7th Edition, ISACA, 2020, p. 104.

When remediation is delayed, compensating controls provide interim protection by reducing risk to acceptable levels.

It is most important that security controls for a new system be documented in the system requirements. The system requirements define the functional and non-functional specifications of the system, including the security controls that are needed to protect the system and its data. Documenting the security controls in the system requirements can help ensure that they are designed, developed, tested, and implemented as part of the system development life cycle. Testing requirements, the implementation plan, and the security policy are other documents that may include security controls, but they are not as important as the system requirements. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 5; CRISC Review Manual, 6th Edition, page 212.

Controls should be incorporated into system specifications in the design phase of the system development life cycle (SDLC), because this is the phase where the system requirements are translated into detailed specifications and architectures that define how the system will be built and operated. Incorporating controls in the design phase ensures that the system is secure, reliable, and compliant from the start, and reduces the cost and complexity of implementing controls later in the SDLC. The other options are not the correct answers, because they are not the phases where controls are incorporated into system specifications. The implementation phase is the phase where the system is installed, configured, and tested. The development phase is the phase where the system is coded, integrated, and tested. The feasibility phase is the phase where the system concept and scope are defined and evaluated. References = CRISC: Certified in Risk & Information Systems Control Sample Questions

 Risk culture is the system of values and behaviors present in an organization that shapes risk decisions of management and employees1. Risk culture influences how the organization perceives, responds to, and manages the risks that may affect its objectives, operations, or assets2.

The scenario described in the question best demonstrates an organization’s risk culture, because it shows how the management team’s attitude and actions towards risk are driven by the organization’s values and goals. In this case, the organization’s risk culture is characterized by:

A high risk appetite and tolerance, which means that the organization is willing to take and accept significant risks in order to achieve its strategic objectives of launching a new product and penetrating new markets

A low risk awareness and sensitivity, which means that the organization does not pay enough attention or consideration to the potential IT risk factors, threats, and vulnerabilities that may affect its product development and market entry

A weak risk governance and control, which means that the organization does not have adequate or effective policies, procedures, or mechanisms to identify, assess, respond, or monitor the IT risks and their impacts

 The best method to identify unnecessary controls is reviewing system functionalities associated with business processes, because this can help to determine whether the controls are relevant, effective, and efficient for the current business needs and objectives. System functionalities are the capabilities and features of IT systems that support the execution and performance of business processes. Business processes are the set of interrelated activities that transform inputs into outputs to deliver value to customers or stakeholders. By reviewing system functionalities associated with business processes, an organization can assess whether the controls are aligned with the process requirements, expectations, and outcomes, and whether they add value or create waste. The review can also identify any gaps, overlaps, redundancies, or conflicts among the controls, and any changes or improvements that are needed to optimize the controls. The other options are less effective methods to identify unnecessary controls. Evaluating the impact of removing existing controls can help to measure the benefits and costs of the controls, but it does not address the root causes or sources of the unnecessary controls. Evaluating existing controls against audit requirements can help to ensure compliance and assurance, but it does not considerthe business context or purpose of the controls. Monitoring existing key risk indicators (KRIs) can help to measure the level and impact of risks, but it does not evaluate the suitability oradequacy of the controls. References = Surveying Staff to Identify Unnecessary Internal Controls - Methodology and Results 

Residual risk is the remaining risk after implementing risk responses, such as controls or mitigation strategies. With the deployment of an IAM solution, the organization has addressed certain access-related risks. Updating the risk register to reflect the new residual risk levels ensures accurate tracking and informs future risk management decisions.

The business unit owner is accountable for authorizing application access in a SaaS environment because they are responsible for aligning access controls with business needs. They determine the roles and permissions needed to ensure operational effectiveness while adhering to the principle ofAccess Managementin the CRISC framework.

The internal auditor is the best suited to provide objective input when updating residual risk to reflect the results of control effectiveness. The internal auditor is an independent and impartial function that evaluates the adequacy and effectiveness of the internal controls and reports on the findings and recommendations. The internal auditor can provide an unbiased and reliable assessment of the residual risk, which is the risk that remains after the controls are applied. The other options are not as objective as the internal auditor, as they may have vested interests orconflicts of interest in the control environment. References = Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.4: IT Risk Response, page 87.

The most important objective of information security controls is to provide measurable risk reduction. Information security controls are the policies, procedures, techniques, or technologies that are implemented to protect the confidentiality, integrity, and availability of information assets. The main purpose of information security controls is to reduce the risk of unauthorized access, use, disclosure,modification, or destruction of information assets, and to ensure that the information assets support the enterprise’s objectives and performance. Information security controls should be measurable, meaning that they should have clear and quantifiable criteria for evaluating their effectiveness and efficiency in reducing the risk exposure to an acceptable level. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.1.1, page 1151

Identifying potential sources of risk is the first step in the risk identification process, which is essential for developing a thorough understanding of risk scenarios. Sources of risk can be internal or external, and can include factors such as people, processes, technology, environment, regulations, and events. Identifying potential sources of risk can help to generate a comprehensive list of risk scenarios that can affect the organization’s objectives and operations. Identifying potential sources of risk can also help to raise risk awareness among the employees and to foster a risk culture within the organization. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.2.1, p. 66-67

The risk practitioner shouldfirst review the methodology of the BIAbecause the BIA identifies critical processes and the impacts of disruptions. This ensures that any identified risks are grounded in reliable, updated business impact data.

===========

 Residual risk is the risk that remains after security controls have been implemented on a system. Residual risk can be accepted, transferred, avoided, or further mitigated. The most important consideration when deciding whether to accept residual risk is the cost versus benefit of additional mitigating controls. This means comparing the potential impact of the residual risk with the cost and effectiveness of implementing more controls to reduce it. If the cost of additional controls outweighs the benefit of reducing the residual risk, then it may be acceptableto accept the residual risk. However, if the benefit of additional controls exceeds the cost, then it may be advisable to implement more controls to lower the residual risk to an acceptable level. References = Risk and Information Systems Control Study Manual, Chapter 3: Risk Response and Mitigation, Section 3.4: Risk Response Selection, p. 156-157.

The best tool to enable risk-based decision making in support of a business continuity plan (BCP) is an impact analysis. An impact analysis is a process of identifying and evaluating the potential effects of an interruption or disruption of business operations on the organization’scritical functions, processes, and resources. An impact analysis can help to determine the recovery priorities, objectives, and strategies forthe BCP. Control analysis, root cause analysis, and threat analysis are other possible tools, but they are not as effective as an impact analysis. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 12; CRISC Review Manual, 6th Edition, page 215.

The greatest challenge for a risk practitioner during a merger of two organizations is the variances between organizational risk appetites, as they may indicate a significant difference in the risk culture, strategy, and objectives of the two organizations, and may require a complex and lengthy process of alignment and integration. Different taxonomies to categorize risk scenarios, disparate platforms for governance, risk, and compliance (GRC) systems, and dissimilar organizational risk acceptance protocols are not the greatest challenges, as they are more related to the technical, operational, or procedural aspects of risk management, rather than the strategicor cultural aspects of risk management. References = CRISC Review Manual, 7th Edition, page 109.

Introducing control procedures early in the IoT solution life cycle ensures proactive identification and mitigation of risks. This approach aligns withSecure System Development PracticesandRisk Mitigation Strategies, reducing exposure as the solution evolves.

The three lines of defense model is a framework that defines the roles and responsibilities of different functions in an organization for managing risks and ensuring effective internal control1. The three lines of defense are:

The first line of defense: the operational management and staff who are responsible for implementing and maintaining the internal control system and managing the risks within their areas of activity

The second line of defense: the oversight functions, such as risk management, compliance, and quality assurance, who provide guidance, support, and monitoring to the first line of defense and ensure that the internal control system is designed and operating effectively

The third line of defense: the internal audit function, who provides independent and objective assurance to the board and senior management on the adequacy and effectiveness of the internal control system and the performance of the first and second lines of defense2

The three lines of defense model facilitates a completely independent review of test results for evaluating control effectiveness, because it ensures that the internal audit function, as the third line of defense, has the authority, independence, and competence to conduct objective and unbiased assessments of the internal control system and report its findings and recommendations to the board and senior management3. The internal audit function can also use the test results from the first and second lines of defense as inputs for its own audit planning and testing, and verify their validity and reliability4.

 The primary reason for establishing various threshold levels for a set of key risk indicators (KRIs) is to take appropriate actions in a timely manner. KRIs are metrics that provide information on the level of exposure to a given risk or the effectiveness of the controls in place. Threshold levels are predefined values that indicate when the risk level is acceptable, tolerable, or unacceptable. By establishing various threshold levels for a set of KRIs, the enterprise can monitor the risk situation and trigger the necessary responses before the risk becomes too severe or costly to mitigate. The other options are not the primary reasons for establishing various threshold levels, although they may be secondary benefits or outcomes of doing so. References = Risk and Information Systems Control Study Manual, Chapter 5: Risk and Control Monitoring and Reporting, page 189.

According to the CRISC Review Manual1, the risk register is a tool that records the results of risk identification, analysis, evaluation, and treatment. It should be updated whenever there is a change in the risk profile, such as when a vulnerability is closed or a new threat is identified. Updating the risk register allows the organization to monitor the current status of risks and the effectiveness of risk responses. Therefore, the next course of action after implementing changes to close an identifiedvulnerability is to update the risk register with the new information. References = CRISC Review Manual1, page 191.

Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Risk appetite provides the most important information to facilitate a risk response decision, because it reflects the organization’s risk tolerance, preferences, and expectations, which guide the selection and implementation of the risk response strategies. Risk appetite helps the organization to balance the potential benefits and costs of taking risks, and to align the risk management process with the organizational strategy and culture. The other options are not as important as risk appetite, because they do not indicate the organization’s desired level of risk exposure, but rather provide supplementary or partial information for the risk response decision, as explained below:

A. Audit findings are the results and recommendations of the internal or external audit activities that evaluate the effectiveness and efficiency of the organization’s governance, risk management, and control processes. Audit findings provide useful information to facilitate a risk response decision, because they can identify the gaps or weaknesses in the current risk response strategies, and suggest corrective actions or improvements. However, audit findings do not indicate the organization’s risk appetite, which is the basis for determining the optimal risk response strategies.

C. Key risk indicators (KRIs) are metrics that measure the impact and likelihood of the risks, and provide early warning signs of changes in the risk exposure. KRIs provide useful information to facilitate a risk response decision, because they can monitor and report the performance and effectiveness of the current risk response strategies, and trigger corrective actions or adjustments.However, KRIs do not indicate the organization’s risk appetite, which is the basis for determining the acceptable level of risk exposure and performance.

D. Industry best practices are the standards, norms, and expectations for risk management that are established and followed by the peers or competitors in the same industry or sector. Industry best practices provide useful information to facilitate a risk response decision, because they can benchmark and compare the organization’s risk response strategies with those of the leading or successful organizations, and identify areas for improvement or innovation. However, industry best practices do not indicate the organization’s risk appetite, which is the basis for determining the unique and customized risk response strategies that suit the organization’s needs and goals. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.2.2, page 40. Risk Appetite: What It Is and How to Use It, Risk Appetite: How Hungry Are You?, Risk Appetite: The Strategic Balancing Act

This can help to:

Ensure that the implemented measures are effective and efficient in reducing the risk level to an acceptable level, and that they are aligned with the risk appetite and tolerance of the organization2.

Identify and address any gaps, issues, or challenges that may arise from the deviation from the approved risk action plan, and recommend and implement appropriate improvement actions or contingency plans3.

Communicate and report the results and outcomes of the validation to the relevant stakeholders, such as the risk owner, the risk committee, or the chief risk officer, and obtain their feedback and approval4.

The other options are not the best course of action, because:

Reporting the observation to the chief risk officer (CRO) is not the best course of action, as it may not provide sufficient information or evidence to support the deviation from the approved risk action plan. The CRO may not be able to evaluate or approve the implemented risk mitigation measures without knowing their adequacy or impact on the risk level5.

Updating the risk register with the implemented risk mitigation actions is not the best course of action, as it may not reflect the current or accurate risk status or performance. The risk register is a document that records and summarizes the key information and data about the identified risks and the risk responses6. Updating the risk register without validating the adequacy of the implemented risk mitigation measures may create inconsistencies or inaccuracies in the risk register.

Reverting the implemented mitigation measures until approval is obtained is not the best course of action, as it may expose the organization to higher or unacceptable levels of risk. Reverting the implemented mitigation measures may undo or negate the benefits or outcomes of the risk mitigation, and may increase the likelihood or impact of the risk events7.

Measurability and consistency are the most essential attributes of an effective key control indicator (KCI), because they ensure that the KCI can be quantified, compared, and reported over time. A KCI should be able to measure the performance or effectiveness of a control in mitigating a risk and provide consistent results across different periods, sources, and methods. The other options are not the most essential attributes, although they may also be desirable for a KCI. Flexibility and adaptability are not the most essential attributes, because they may compromise the reliability and comparability of the KCI. Robustness and resilience are not the most essential attributes, because they are more relevant for the control itself, not the KCI. Optimal cost and benefit are not the most essential attributes, because they are more related to the value and feasibility of the KCI, not the quality and accuracy of the KCI. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers

When developing a response plan to address security incidents regarding sensitive data loss, it is most important to review the data classification policy. A data classification policy is a document that defines the categories and levels of data based on their sensitivity, value, and criticality, and specifies the appropriate security measures and handling procedures for each data type. A data classification policy helps to identify and protect the sensitive data that could be exposed or compromised in a security incident, and to comply with the relevant laws, regulations, standards, and contracts. Reviewing the data classification policy is important when developing a response plan, because it helps to determine the scope, impact, and priority of the security incident, and to select the most appropriate and effective response actions and strategies. Reviewing the data classification policy also helps to communicate and coordinate the response plan with the internal and external stakeholders, such as the data owners, users, custodians, and regulators, and to report and disclose the security incident as required. The other options are not as important as reviewing the data classification policy, although they may be part of or derived from the response plan. Revalidating current key risk indicators (KRIs), revising risk management procedures, and revalidating existing risk scenarios are all activities that can help to improve or update the risk management process, but they are not the most important when developing aresponse plan. References = Risk and Information Systems Control Study Manual, Chapter 5, Section 5.3.1, page 5-25.

An internal data access policy is a set of rules and guidelines that define who, how, when, and why the users can access, use, share, or modify the data stored in a business application system, based on the data classification, sensitivity, and ownership.

Enforcing an internal data access policy is the most appropriate way to prevent unauthorized retrieval of confidential information stored in a business application system. This means that the organization implements and maintains effective controls to ensure that only the authorized users can access the confidential information, and that the access is logged and monitored for compliance and security purposes.

The other options are not the most appropriate ways to prevent unauthorized retrieval of confidential information stored in a business application system. They are either secondary or not essential for data access control.

An IT risk and control self-assessment (RCSA) is a process that helps organizations identify and evaluate operational risks and assess the effectiveness of their control measures12. It is a structured approach that involves identifying, assessing, mitigating, and monitoring risks across all levels of an organization12.

A report to senior management is a document that summarizes and communicates the results and findings of the RCSA, and provides recommendations and action plans for improving the risk management and control processes34.

The most important aspect of an IT risk and control self-assessment to include in a report to senior management is an increase in residual risk, which is the risk remaining after risk treatment, and represents the exposure or potential impact of the risk on the organization’s objectives56.

An increase in residual risk is the most important aspect because it indicates the level of risk that the organization is willing to accept or tolerate, and the gap between the current and desired risk profile56.

An increase in residual risk is also the most important aspect because it requires the attention and decision of the senior management, who are responsible for defining the organization’s risk appetite, strategy, and criteria, and for ensuring that the residual risk is within the acceptable range56.

The other options are not the most important aspects, but rather possible components or outcomes of an IT risk and control self-assessment that may support or complement the report to senior management. For example:

Changes in control design are components of an IT risk and control self-assessment that involve modifying or updating the control measures to address the changes in the risk environment or the organization’s objectives56. However, changes in control design are not the most importantaspect because they do not measure or reflect the residual risk, which is the ultimate goal of the risk treatment56.

A decrease in the number of key controls is an outcome of an IT risk and control self-assessment that indicates the improvement or optimization of the control processes, and the reduction of the complexity or redundancy of the control measures56. However, a decrease in the number of key controls is not the most important aspect because it does not indicate or imply the residual risk, which may depend on other factors such as the effectiveness or efficiency of the controls56.

Changes in control ownership are components of an IT risk and control self-assessment that involve assigning or reassigning the responsibility and accountability for the control processes to the appropriate individuals or groups within the organization56. However,changes in control ownership are not the most important aspect because they do not affect or determine the residual risk, which is independent of the control owners56. References =

Determining the value of data is essential when implementing a DLP system. Understanding data value helps prioritize protection efforts, allocate resources effectively, and ensure that critical information assets are adequately safeguarded against loss or unauthorized access.

A threat risk assessment will best quantify the risk associated with malicious users in an organization, because it focuses on identifying and evaluating the potential sources of harm or damage to the organization’s assets, such as data, systems, or networks. A malicious user is a person who intentionally and unauthorizedly accesses, modifies, destroys, or steals the organization’s information or resources, for personal gain, revenge, espionage, or sabotage. A threat risk assessment can help the organization to estimate the likelihood and impact of malicious user attacks, based on factors such as the user’s motivation, capability, opportunity, and access level. A threat risk assessment can also help the organization to determine the appropriate risk response strategies, such as prevention, detection, mitigation, or transfer, to reduce the risk exposure and impact of malicious user attacks. References = Risk IT Framework, ISACA, 2022, p. 141

Key risk indicators (KRIs) are metrics that provide information on the level of exposure to a given operational risk1. KRIs have upper and lower acceptable risk limits (warning thresholds) that trigger actions when exceeded2. These thresholds are based on the organization’s risk appetite or tolerance, which is the amount and type of risk that the organization is willing to accept in pursuit of its objectives3. Therefore, changes in risk appetite or tolerance would prompt changes in KRI thresholds, as the organization would need to adjust its risk monitoring and response accordingly. The other options are not the primary factors that would prompt changes in KRI thresholds, although they may have some influence on the risk management process. References = Risk IT Framework; IT Risk Resources; ISACA Risk Starter Kit; Key Risk Indicators; Key Risk Indicators: A Practical Guide

The best way to ensure key risk indicators (KRIs) provide value to risk owners is to provide timely notification of the changes in the risk exposure. KRIs are metrics that provide an early warning of increasing risk exposure in various areas of the organization. By providing timely notification of the KRI values, the risk owners can be alerted of the risk situation and take appropriate actions to manage the risk. Ongoing training, return on investment (ROI), and cost minimization are other possible ways to ensure KRIs provide value, but they are not as effective as timely notification. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 10; CRISC Review Manual, 6th Edition, page 140.

Independent third-party audits provide an objective review of a vendor’s control environment. They are often formalized in reports such as SOC 2 or ISO audits, giving the organization the highest level of assurance about the effectiveness of vendor controls.

 The best way to facilitate the development of effective IT risk scenarios is to utilize a cross-functional team. A cross-functional team is a group of people with different skills, expertise, and perspectives who work together to achieve a common goal. A cross-functional team can help to create realistic, comprehensive, and relevant IT risk scenarios by bringing diverse knowledge, experience, and insights from various domains and functions. A cross-functional team can alsohelp to identify and address the interdependencies, interactions, and impacts of IT risks across the organization. The other options are not the best ways to facilitate the development of effective IT risk scenarios, although they may be useful or necessary depending on the context and nature of the IT risks. Participation by IT subject matter experts is important, but it is notsufficient, as IT risks may affect or be affected by non-IT factors and stakeholders. Integration of contingency planning is a part of the risk response process, which follows the risk scenario development process, but it is not the same as creating the risk scenarios. Validation by senior management is a quality assurance step that ensures the accuracy and completeness of the risk scenarios, but it is not the same as facilitating the development of the risk scenarios. References = Six Steps to Using Risk Scenarios for Improved Risk Management, IT Risk Scenarios - Morland-Austin, IT Risk Resources | ISACA

A digital certificate is a document that contains the public key and the identity of the owner of the public key, and is signed by a trusted third party called a certificate authority (CA)1. A digital certificate can be used to ensure the message reaches the intended recipient without alteration, by using the following steps2:

The sender encrypts the message with the recipient’s public key, which can only be decrypted by the recipient’s private key. This ensures the confidentiality of the message, as only the intended recipient can read it.

The sender signs the message with their own private key, which can be verified by anyone who has their public key. This ensures the integrity and authenticity of the message, as it proves that the message has not been tampered with and that it comes from the sender.

The sender attaches their digital certificate to the message, which contains their public key and their identity, and is signed by a CA. This ensures the validity and trustworthiness of the sender’s public key and identity, as it confirms that they have been verified by a CA.

The recipient receives the message and the digital certificate, and verifies the signature of the CA on the digital certificate. This ensures that the digital certificate is genuine and has not been forged or revoked.

The recipient uses the public key from the digital certificate to verify the signature of the sender on the message. This ensures that the message has not been altered and that it comes from the sender.

The recipient uses their own private key to decrypt the message. This ensures that they can read the message.

Therefore, adding a digital certificate is the best way to ensure the message reaches the intended recipient without alteration, as it provides encryption, digital signature, and certificate verification, which are the three main components of secure email communication3. Applying multi-factor authentication, adding a hash to the message, and adding a secret key are not the best ways to ensure the message reaches the intended recipient without alteration, as they do not provide all the components of secure email communication. Applying multi-factor authentication is a technique that requires the user to provide two or more pieces of evidence to prove their identity, such as a password, a code, or a biometric factor4. Multi-factor authentication can enhance the security of the email account, but it does not protect the message itselffrom being intercepted, modified, or impersonated. Adding a hash to the message is a technique that involves applying a mathematical function to the message to generate a fixed-length value, called a hash or a digest, that uniquely represents the message5. A hash can be used to verify the integrity of the message, as any change in the message will result in a different hash. However, ahash does not provide confidentiality or authenticity of the message, as it does not encrypt themessage or identify the sender. Adding a secret key is a technique that involves using a single key, known only to the sender and the recipient, to encrypt and decrypt the message6. A secret key can provide confidentiality of the message, as only the sender and the recipient can read it. However, a secret key does not provide integrity or authenticity of the message, as it does not prevent the message from being altered or spoofed. Moreover, a secret key requires a secure way of exchanging the key between the sender and the recipient, which may not be feasible or reliable over email. References = 1: What is a digital certificate? | Norton2: How to Send Secure Emails in 2023 | A Guide to Secure Email - ProPrivacy3: Secure Email: A Complete Guide for 2023 - StartMail4: What is Multi-Factor Authentication (MFA)? | Duo Security5: What is a Hash Function? | Definition and FAQs6: [What is Symmetric Encryption? | Definition and FAQs]

The most important thing to include in a risk assessment of an emerging technology is the impact and likelihood ratings of the risks associated with the technology. Impact and likelihood ratings are the measures of the potential consequences and probabilities of the risk events that could affect the achievement of the enterprise’s objectives. Impact and likelihood ratings can help to evaluate the level andnature of the risk exposure, and to prioritize the risks for further analysis and response. Impact and likelihood ratings can also help to communicate the risk profile and appetite of the enterprise, and to support the risk-based decision making. Risk response plans, risk and control ownership, and key controls are not as important as impact and likelihood ratings, as they are the outputs or outcomes of the risk assessment process, and not the inputs or components of the risk assessment process. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 49.

Strategic decisions on risk management are the decisions that involve setting the direction, objectives, and priorities for risk management within an organization, as well as aligning them with the organization’s overall strategy, vision, and mission1. Strategic decisions on riskmanagement also involve defining the organization’s risk appetite and tolerance, which are the amount and level of risk that the organization is willing and able to accept to achieve its goals2. The responsibility for strategic decisions on risk management should belong to the executive management team, which is the group of senior leaders who have the authority and accountability for the organization’s performance and governance3. The executive management team has the best understanding of the organization’s strategic context, environment, and stakeholders, and can make informed and balanced decisions that consider the benefits and costsof risk-taking4. The executive management team also has the ability and responsibility to communicate and cascade the strategic decisions on risk management to the rest of the organization, and to monitor and evaluate their implementation and outcomes5. The chief information officer (CIO), the audit committee, and the business process owner are not the best choices for being responsible for strategic decisions on risk management, as they do not have the same level of authority and accountability as the executive management team. The CIO is the senior leader who oversees the organization’s information andtechnology strategy, resources, and systems6. The CIO may be involved in providing input and feedback to the executive management team on the strategic decisions on risk management, especially those related to IT risk, but they do not have the final say or the overall responsibility for them. The audit committee is a subcommittee of the board of directors that oversees the organization’s financial reporting, internal controls, and external audits7. The audit committee may be involved in reviewing and approving the strategic decisions on risk management, as well as ensuring their compliance with the relevant laws and standards, but they do not have the authority or the expertise to make or implement them. The business process owner is the person who has the authority and accountability for a business process that supports or enables the organization’s objectives and functions. The business process owner may be involved in executing and reporting on the strategic decisions on risk management, as well as identifying and mitigating the risks related to their business process, but they do not have the perspective or the influence to make or communicate them. References = 1: Strategic Risk Management: Complete Overview (With Examples)2: [Risk Appetite and Tolerance - ISACA] 3: [Senior Management - Definition, Roles andResponsibilities] 4: Stanford Strategic Decision and Risk Management | Stanford Online5: A 7-Step Process for Strategic Risk Management — RiskOptics - Reciprocity6: [Chief Information Officer (CIO) - Gartner ITGlossary] 7: [Audit Committee - Overview, Functions, and Responsibilities] : [Business Process Owner - Gartner IT Glossary] : [Business Process Owner - Roles and Responsibilities] : [Risk and Information Systems Control Study Manual, Chapter 1: IT Risk Identification, Section 1.1: IT Risk Concepts, pp. 17-19.]

A risk map is a visual tool that helps to communicate risk to management by showing the likelihood and impact of different risks on a matrix1. A risk map can help to:

Identify the most critical risks that need immediate attention or action

Compare and prioritize risks based on their severity and probability

Align risk management strategies with the organization’s risk appetite and tolerance

Communicate risk information in a clear and concise way that is easy to understand and interpret2

The primary consideration for determining recovery priorities in a disaster recovery situation is the impact of business disruption on the organization’s mission, objectives, and stakeholders. Business disruption can result in loss of revenue, reputation, customer satisfaction, market share, and competitive advantage. Therefore, the recovery priorities should be based on the criticality of the business processes and functions that support the organization’s value proposition and strategic goals. Data security (A), recovery costs (B), and recovery resource availability (D) are important factors, but they are secondary to the impact of business disruption. Data security should be ensured throughout the recovery process, but it does not determine the recovery order. Recovery costs should be balanced with the benefits of restoring the business operations, but they do not reflect the urgency of the recovery. Recovery resource availability should be assessed and allocated according to the recovery priorities, but it does not define the recovery sequence. (Risk and Information Systems Control Review Questions, Answers & Explanations Manual, 5th Edition, page 982)

The best control to reduce the likelihood of a successful network attack through social engineering is security awareness training. Security awareness training is a program that educates and trains employees on the common types, techniques, and indicators of social engineering attacks, such as phishing, baiting, pretexting, and quid pro quo12. Security awareness training also teaches employees how to protect themselves and the organization from social engineering attacks, such as by verifying the identity and legitimacy of the sender or caller, avoiding clicking on suspicious links or attachments, reporting any suspicious or unusual activity, and following the organization’s security policies and procedures. Security awareness training can help to reduce the likelihood of a successful network attack through social engineering, because it can increase the employees’ knowledge, skills, and confidence in recognizing and responding to social engineering attempts, and it can also foster a culture of security and responsibility among the employees. The other options are not the best control, although they may be useful or complementary to security awareness training. Automated controls are technical or procedural controls that are performed by a system or a device without human intervention, such as firewalls, antivirus software, encryption, and backups. Automated controls can help to protect the network from external or internal threats, but they may not be effective against social engineering attacks, which rely on humaninteraction and manipulation.Multifactor authentication is a security mechanism that requires users to provide two or more pieces of evidence to verify their identity and access a system or a service, such as a password, a token, a fingerprint, or a facial recognition. Multifactor authentication can help to prevent unauthorized access to the network, but it may not prevent social engineering attacks, which may persuade users to share or compromise their authentication factors. Employee sanctions are disciplinary actions that are taken against employees who violate the organization’s security policies and procedures, such as warnings, fines, suspensions, or terminations. Employee sanctions can help to deter and punish employees who fall victim to or facilitate social engineering attacks, but they may not prevent or reduce the likelihood of social engineering attacks, and they may also create a negative or fearful work environment. References = Avoiding Social Engineering and Phishing Attacks | CISA, What is Social Engineering | Attack Techniques & Prevention Methods …, 10 Types of Social Engineering Attacks - CrowdStrike
