Isaca CRISC Actual Questions

The most appropriate action for the risk manager to take after undertaking a risk assessment of a production system is to inform the process owner of the concerns and propose measures to reduce them, as the process owner has the authority and responsibility to manage the production system and its associated risks and controls, and to decide on the optimal risk response. Recommending a program that minimizes the concerns of that production system, informing the IT manager of the concerns and proposing measures to reduce them, and informing the development team of the concerns and together formulating risk reduction measures are not the most appropriate actions, as they may not involve the process owner, who is the key stakeholder and decision maker for the production system and its risks. References = CRISC Review Manual, 7th Edition, page 101.

Segregation of duties is a key control for preventing and detecting fraudulent transactions, especially in a large organization where there are many employees and transactions involved. Segregation of duties means that no single person has the authority or ability to initiate, approve, execute, and record a transaction without the involvement or oversight of another person. This reduces the opportunity and incentive for fraud, as well as the risk of errors or omissions. Segregation of duties also facilitates the detection of fraud by creating an audit trail and increasing the likelihood of whistleblowing.

The other options are not as effective as segregation of duties for mitigating risk related to fraudulent transactions. Monetary approval limits (B) are useful for controlling the amount and frequency of transactions, but they do not prevent unauthorized or fraudulent transactions from occurring. Clear roles and responsibilities © are important for defining the expectations and accountabilities of employees, but they do not ensure that employees comply with them or that their actions are monitored and verified. Password policies (D) are essential for securing access to systems and data, but they do not prevent fraudsters from exploiting weak or compromised passwords or from using legitimate passwords for fraudulent purposes.

According to the ISACA Risk and Information Systems Control study guide and handbook, the control owners in the IT department should determine whether risk responses still effectively address risk after a restructuring and outsourcing of certain functions. This is because the restructuring and outsourcing may have changed the risk profile, the control environment, and the control activities of the IT department. The control owners should review the existing risk responses and evaluate if they are still appropriate, adequate, and efficient in mitigating the risks associated with the outsourced functions. The control owners should also monitor the performance and compliance of the service providers and ensure that the contractual obligations and service level agreements are met12

 Segmenting the application within the existing network is the most effective control to manage a legacy application that relies on software that has reached the end of extended support, as it isolates the application from the rest of the network and reduces the attack surface and the potential impact of a compromise. Subscribing to threat intelligence, applying patches for a newer version of the application, and increasing the frequency of regular system and data backups are not the most effective controls, as theymay not address the root cause of the risk, or may introduce additional costs or complexities, respectively. References = CRISC Review Manual, 7th Edition, page 153.
