A. B. C. D.

C.

When conducting an audit of a virtual server farm for potential software vulnerabilities, an IS auditor would consider the greatest risk to be the one that poses the highest potential impact or likelihood of exploitation. Let's analyze each option to determine which one represents the greatest risk:

A. The hypervisor is updated quarterly: This option suggests that the hypervisor is updated regularly, which is a good practice. However, it does not provide information on the currency or effectiveness of the updates. As a result, it is not the greatest risk.

B. Guest operating systems are updated monthly: This option suggests that the guest operating systems are also updated regularly, which is another good practice. However, like the previous option, it does not provide information on the currency or effectiveness of the updates. Therefore, it is not the greatest risk.

C. Antivirus software has been implemented on the guest operating system only: This option indicates that antivirus software has been implemented only on the guest operating system and not on the hypervisor or other critical areas of the server farm. This creates a vulnerability that could be exploited by malware or viruses that bypass the antivirus software on the guest operating system. This risk can be considered greater than the previous options.

D. A variety of guest operating systems operate on one virtual server: This option suggests that multiple guest operating systems are running on a single virtual server. This increases the risk of vulnerabilities or security breaches because a security issue with one guest operating system could potentially affect all others. Thus, this option could also be considered a significant risk.

Therefore, the greatest risk when conducting an audit of a virtual server farm for potential software vulnerabilities could be either option C or option D, depending on the specific context of the system being audited.
