 Partitioning the work environment from personal space on devices. This would best maintain information security without compromising employee privacy by creating a separate and secure area on the personal mobile devices for work-related data and applications. This way, the organization can protect its information from unauthorized access, loss, or leakage, while respecting the employees’ personal data and preferences on their own devices.

The other options are not as effective as option B in balancing information security and employee privacy. Option A, installing security software on the devices, is a good practice but may not be sufficient to prevent data breaches or comply with regulatory requirements. Option C, preventing users from adding applications, is too restrictive and may interfere with the employees’ personal use of their devices. Option D, restricting the use of devices for personal purposes during working hours, is impractical and difficult to enforce.

The best approach to optimize resources when both internal and external audit teams are reviewing the same IT general controls area is to leverage the work performed by external audit for the internal audit testing. This can avoid duplication of efforts, reduce audit costs and enhance coordination between the audit teams. The internal audit team should evaluate the quality and reliability of the external audit work before relying on it. Ensuring both the internal and external auditors perform the worksimultaneously is not an efficient use of resources, as it would create redundancy and possible interference. Requesting that the external audit team leverage the internal audit work may not be feasible or acceptable, as the external audit team may have different objectives, standards and independence requirements. Rolling forward the general controls audit to the subsequent audit year is not a good practice, as it would delay the identification and remediation of any control weaknesses in a high-risk area. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 247

 The auditor’s primary concern when capacity management for a key system is being performed by IT with no input from the business would be an unanticipated increase in business’s capacity needs. This could result in performance degradation, service disruption or customer dissatisfaction if IT is not able to provide sufficient capacity to meet the business demand. Failure to maximize the use of equipment, cost of excessive data center storage capacity or impact to future business project funding are secondary concerns that relate to resource optimization or budget allocation, but not to service delivery or customer satisfaction. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 374

 The IS auditor should ensure that penetration test results are classified at the highest level of sensitivity, because they contain detailed information about the vulnerabilities and weaknesses of the IT systems and networks, as well as the methods and tools used by the testers to exploit them. Penetration test results can be used by malicious actors to launch cyberattacks or cause damage to the organization if they are disclosed or accessed without authorization. Therefore, they should be protected with the highest level of confidentiality, integrity and availability. The other options are not as sensitive as penetration test results, because they either do not reveal as muchinformation aboutthe IT security posture, or they are already known or reported by the organization. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4
