Operational Aspect for Assessing an Assembly Line with Wireless Quality Control Sensors

C.

When assessing an assembly line with quality control sensors accessible via wireless technology, an IS auditor should consider various operational aspects. However, the MOST important aspect is device security, making option C the correct answer.

Wireless technology is vulnerable to security threats such as unauthorized access, data interception, and modification. Attackers can exploit known vulnerabilities in the wireless devices to gain unauthorized access and steal sensitive information, or to manipulate the quality control sensors to produce substandard products.

An IS auditor should, therefore, focus on assessing the security of the wireless devices used in the assembly line. This includes ensuring that the devices are updated with the latest security patches and firmware to address any known vulnerabilities. The auditor should also examine the security controls implemented to protect the wireless devices, such as strong authentication and encryption mechanisms, access controls, and intrusion detection and prevention systems.

Resource utilization is also an important aspect to consider, as wireless devices require adequate resources to function correctly. The IS auditor should assess the availability and utilization of the resources, such as network bandwidth and battery life, to ensure that they are adequate and do not compromise the security of the assembly line.

While known vulnerabilities are critical to consider, they are not the MOST important aspect since an IS auditor should always prioritize security to protect against all types of attacks, including those not yet known.

Therefore, in summary, the MOST important operational aspect for an IS auditor to consider when assessing an assembly line with quality control sensors accessible via wireless technology is device security (Option C).
