 The BEST way to enable mitigation of newly identified risk factors related to internet of Things (loT) is to introduce control procedures early in the life cycle, because it can help to prevent or reduce the occurrence or impact of the risk factors, and to ensure that the loT devices and systems are designed and developed with security and quality in mind. The control procedures should include requirements analysis, design review, testing, validation, and verification of the loT devices and systems. The other options are not as effective as introducing control procedures early in the life cycle, because:

Option B: Implementing loT device software monitoring is a good way to detect and respond to the risk factors related to loT, but it does not enable mitigation of the risk factors, which is the proactive and preventive approach. Software monitoring is a reactive and corrective measure that may not be able to prevent or reduce the occurrence or impact of the risk factors, especially if they are embedded in the hardware or firmware of the loT devices.

Option C: Performing periodic risk assessments of loT is a necessary way to identify and evaluate the risk factors related to loT, but it does not enable mitigation of the risk factors, which is the action-oriented and solution-focused approach. Risk assessment is an analytical and descriptive process that may not provide the specific and effective measures to address or mitigate the risk factors, especially if they are complex or dynamic.

Option D: Performing secure code reviews is a useful way to verify and improve the security and quality of the software of the loT devices and systems, but it does not enable mitigation of the risk factors related to loT, which may involve more than just the software aspect. The risk factors related to loT may also include the hardware, firmware, network, communication, data, and integration aspects, which may not be covered or resolved by the code reviews. References = Risk and Information Systems Control Study Manual, 7th Edition, ISACA, 2020, p. 214.

 The MOST important consideration when performing a risk assessment of a fire suppression system within a data center is the maintenance procedures, because they ensure that the fire suppression system is functioning properly and reliably, and that it can prevent or minimize the damage caused by fire incidents. The maintenance procedures should include regular testing, inspection, and servicing of the fire suppression system components, such as sprinklers, detectors, alarms, and extinguishers. The other options are not as important as the maintenance procedures, because:

Option A: Insurance coverage is a financial measure that can compensate for the loss or damage caused by fire incidents, but it does not prevent or reduce the likelihood or impact of the fire incidents. Insurance coverage is also dependent on the terms and conditions of the insurance policy, which may not cover all the scenarios or costs of the fire incidents.

Option B: Onsite replacement availability is a contingency measure that can facilitate the recovery or restoration of the fire suppression system after a fire incident, but it does not prevent or reduce the likelihood or impact of the fire incidents. Onsite replacement availability is also dependent on the availability and compatibility of the replacement parts, which may not match the original fire suppression system specifications or requirements.

Option D: Installation manuals are a reference source that can provide guidance on how to install or configure the fire suppression system, but they do not ensure that the fire suppression system is functioning properly and reliably. Installation manuals are also static documents that may not reflect the current or updated fire suppression system standards or practices. References = Risk and Information Systems Control Study Manual, 7th Edition, ISACA, 2020, p. 211.

According to the CRISC Review Manual1, senior management support is the commitment and involvement of the top-level executives and leaders in the risk management process. Senior management support is the most important enabler of effective risk management, as it helps to establish and communicate the risk vision, strategy, and culture of the organization. Senior management support also helps to allocate the necessary resources, authority, and accountability for risk management, and to ensure the alignment of the risk management objectives and activities with the organization’s strategy, goals, and values. References = CRISC Review Manual1, page 198.

 First-hand direct observation of the controls in operation is the best way to confirm the existence and operating effectiveness of information systems controls because it provides the most reliable and persuasive evidence. Direct observation involves inspecting the physical and logical aspects of the controls, such as the hardware, software, network, data, procedures, and personnel involved in the information systems. Direct observation also allows the auditor to verify that the controls are functioning as intended, and to identify any deviations or weaknesses that may affect the reliability of the information systems. Direct observation can be performed by using various techniques, such as walkthroughs, inquiries, inspections, reperformance, and analytical procedures1. References = Auditing Standard No. 13, The Auditor’s Responses to the Risks of Material Misstatement, PCAOB, 2010
