Integrity is the property of data that ensures its accuracy, completeness, and consistency2. If concurrent update transactions to an account are not processed properly, the integrity of the data may be compromised, as it may lead to concurrency problems such as lost update, unrepeatable read, or phantom read3. These problems can cause the data to be incorrect, incomplete, or inconsistent, which may affect the reliability and validity of the data. Therefore, option D is the correct answer, as it reflects the impact of improper concurrent update transactions on the data integrity. The other options are not correct, as they do not directly relate to the effect of concurrent update transactions on the data. Option A, confidentiality, is the property of data that ensures its protection from unauthorized access or disclosure2. Concurrent update transactions do not necessarily affect the confidentiality of the data, as they do not involve exposing the data to unauthorized parties. Option B, accountability, is the property of data that ensures its traceability and auditability2. Concurrent update transactions do not necessarily affect the accountability of the data, as they do not involve losing the records or logs of the data transactions. Option C, availability, is the property of data that ensures its accessibility and usability2. Concurrent update transactions do not necessarily affect the availability of the data, as they do not involve preventing the access or use of the data.

Reviewing the risk register is the best way to help an organization gain insight into its overall risk profile, because it provides a comprehensive and structured representation of all the key risks that the organization faces, along with their likelihood, impact, and response strategies. A risk register is a tool that records and tracks the current status of risks, their sources, causes, consequences, and controls. A risk register helps to facilitate the communication and reporting of risks, and to support the risk-based decision making and prioritization. A risk profile is a summary of the key risks that an organization faces, and their implications forthe organization's objectives and strategy. Reviewing the risk register is the best way to understand the risk profile, as it reflects the nature and level of exposure that the organization has from the various risk sources and scenarios. Reviewing the threat landscape, the risk appetite, and the risk metrics are all useful ways to help an organization gain insight into its overall risk profile, but they are not the best way, as they do not provide a comprehensive and structured view of the risks and their responses.

According to theCRISC 351-400 topic3 Flashcards, the greatest concern when using a generic set of IT risk scenarios for risk analysis is that the risk factors might not be relevant to the organization. This is because generic risk scenarios are not tailored to the specific context, objectives, and environment of the organization, and they may not capture the unique threats, vulnerabilities, and impacts that the organization faces. Therefore, using generic risk scenarios may result in inaccurate or incomplete risk assessment and analysis, and may lead to ineffective or inappropriate risk responses. To avoid this, the organization should customize the risk scenarios to reflect its own situation and needs, and involve the relevant stakeholders and experts in the process.Reference=CRISC 351-400 topic3 Flashcards,Generic IT Risk Scenarios for Risk Analysis: The Greatest Concern

Establishing clear accountability for risk is the best way for an organization to enable risk treatment decisions, as it ensures that the risk owners and stakeholders have the authority and responsibility to manage and mitigate the risks that they are assigned to. Establishing clear accountability for risk also facilitates communication and collaboration among the risk owners and stakeholders, and enables them to monitor and report the risk status and performance. Establishing clear accountability for risk also supports the risk governance and culture of the organization, and aligns the risk management process with the organization's strategy and objectives.Reference=ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, Question 250.CRISC: Certified in Risk & Information Systems Control Sample Questions, Question 250.CRISC Sample Questions 2024, Question 250.CRISC by Isaca Actual Free Exam Q&As, Question 9.

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.
