The best course of action for a system administrator who suspects a colleague may be intentionally weakening a system’s validation controls in order to pass through fraudulent transactions is B. Share the concern through a whistleblower communication channel1

According to the CRISC Review Manual, a whistleblower communication channel is a mechanism that allows employees to report suspected fraud or unethical behavior without fear of retaliation or reprisal. A whistleblower communication channel is part of an effective fraud detection and prevention framework, and it helps to promote a culture of integrity and accountability within the organization2

The other options are not as effective or appropriate as sharing the concern through a whistleblower communication channel, because:

•A. Implementing compensating controls to deter fraud attempts may not address the root cause of the problem, and it may also create additional complexity and cost for the system. Moreover, it may not prevent the colleague from finding other ways to bypass the controls or collude with external parties.

•C. Monitoring the activity to collect evidence may expose the system administrator to legal or ethical risks, especially if the monitoring is done without proper authorization or due process. Itmay also delay the reporting and resolution of the issue, and potentially allow more fraudulent transactions to occur.

•D. Determining whether the system environment has flaws that may motivate fraud attempts may be useful for understanding the context and the factors that contribute to the fraud risk, but it does not address the immediate concern of reporting the suspected fraud. It may also imply that the system administrator is trying to justify or rationalize the colleague’s behavior, rather than holding them accountable.

The proposed benefit that is most likely to influence senior management approval to reallocate budget for a new security initiative is the reduction in residual risk, as it indicates the expected value and outcome of the initiative in terms of reducing the risk exposure and impact to the level that is aligned with the risk tolerance and appetite of the organization. The other options are not the most likely benefits, as they may not reflect the actual or optimal risk reduction, or may not be relevant or measurable for the senior management, respectively. References = CRISC Review Manual, 7th Edition, page 111.

A business system is a set of interconnected processes, functions, or activities that support the operations and objectives of a business1. A security gap is a weakness or flaw in a business system that can be exploited by a threat to cause harm or gain unauthorized access2. A control is a measure or mechanism that reduces the likelihood or impact of a security gap or threat3.

The best way to determine whether new controls mitigate security gaps in a business system is to perform a vulnerability assessment. A vulnerability assessment is a process of identifying and evaluating the security gaps and threats in a business system, and testing the effectiveness and efficiency of the controls that are implemented to address them. A vulnerability assessment can help to:

Measure and compare the current and desired state of the security posture and performance of the business system

Detect and prioritize the most critical and urgent security gaps and threats that may compromise the business system or its objectives

Validate and validate the adequacy and reliability of the new controls and their ability to prevent, detect, or respond to security incidents or breaches

Provide feedback and recommendations for improving the security of the business system and enhancing the security awareness and culture of the organization

When proposing a risk acceptance framework for an organization, the most important consideration for the risk practitioner is to clearly define the individuals or roles authorized to approve risk acceptance. This ensures that the process is controlled, accountable, and aligned with the organization’s risk management policies.

Risk Acceptance Framework:

Purpose:A risk acceptance framework provides structured criteria and processes for deciding whether to accept a risk. This includes evaluating the risk against the organization's risk appetite and tolerance.

Authorization:Identifying who has the authority to accept risk is critical. This ensures that only those with the appropriate knowledge, experience, and understanding of the organization's risk appetite and strategic objectives can make these decisions.

Importance of Authorized Individuals:

Accountability:Clearly defined roles for risk acceptance ensure accountability. It is essential that those making the decisions are accountable for the outcomes and understand the potential impact of their decisions.

Consistency:By defining specific roles, the organization ensures consistency in risk acceptance decisions, reducing the likelihood of ad-hoc or inconsistent risk management practices.

Alignment with Strategy:Authorized individuals are typically those who understand the strategic objectives of the organization, ensuring that risk acceptance aligns with these goals.

According to the CRISC Review Manual, monitoring against the configuration standard is the most effective control to maintain the integrity of system configuration files, because it ensures that any unauthorized or unintended changes are detected and corrected. Monitoring against the configuration standard involves comparing the actual configuration of the system with the approved baseline and identifying any deviations or discrepancies. The other options are not the most effective controls, because they do not ensure the integrity of the system configuration files. Recording changes to configuration files is a good practice, but it does not prevent unauthorized or unintended changes from occurring. Implementing automated vulnerability scanning is a preventive control that helps to identify and remediate potential weaknesses in the system, but it does not verify the integrity of the configuration files. Restricting access to configuration documentation is a security measure that limits the exposure of sensitive information, but it does not prevent unauthorized or unintended changes to the configuration files. References = CRISC Review Manual, 7th Edition, Chapter 4, Section 4.2.3, page 184.

The most important factor for the organization to consider before implementing a new in-house developed artificial intelligence (AI) solution is the expected algorithm outputs, as they define the desired outcomes and objectives of the AI solution, and guide the design, testing, and validation of the AI algorithm. The other options are not the most important factors, as they are more related to the research, input, or monitoring of the AI solution, respectively, rather than the output of the AI solution.

 The most important key performance indicator (KPI) to monitor the effectiveness of disaster recovery processes is the percentage of IT systems meeting the recovery time objective (RTO) during the disaster recovery test. The RTO is the maximum acceptable time that a system orprocess can be unavailable after a disruption. The disaster recovery test is a simulation of a disaster scenario to evaluate the readiness and capability of the organization to restore its critical functions and systems. By measuring the percentage ofIT systems meeting the RTO during the test, the organization can assess how well the disaster recovery processes meet the predefined objectives and standards. Percentage of IT systems recovered within the mean time to restore (MTTR), percentage of issues arising from the disaster recovery test resolved on time, and percentage of IT systems included in the disaster recovery test scope are other possible KPIs, but they are not as important as the percentage of IT systems meeting the RTO. 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 most reliable evidence of the effectiveness of security controls implemented for a web application is penetration testing. Penetration testing is a process that simulates an attack on the web application by exploiting its vulnerabilities, using the same tools and techniques as real attackers. Penetration testing helps to evaluate the effectiveness of security controls, because it helps to verify that the security controls can prevent, detect, or mitigate the attack, and to measure the impact and severity of the attack. Penetration testing also helps to identify and address any weaknesses or gaps in the security controls, and to provide recommendations andsolutions for improving the security of the web application. The other options are not as reliable as penetration testing, although they may provide some evidence of the effectiveness of security controls. IT general controls audit, vulnerability assessment, and fault tree analysis are all examples of analytical or evaluative methods, which may help to assess or estimate the effectiveness of security controls, but they do not necessarily test or measure the effectiveness of security controls in a realistic scenario. References = 10
