Of the options given, the most significant risk an IS auditor should consider when reviewing a credit card company's application system is data privacy.
Data privacy is a critical concern for any organization that handles sensitive information, such as credit card details. A credit card company's application system will likely collect and store vast amounts of personal and financial information about its customers, including names, addresses, social security numbers, credit card numbers, and other sensitive data.
If this information falls into the wrong hands, it can be used for identity theft, credit card fraud, and other malicious activities. A breach of data privacy can damage the credit card company's reputation, result in legal action, and lead to significant financial losses.
Therefore, an IS auditor should focus on ensuring that the credit card company's application system has adequate security controls in place to protect sensitive data from unauthorized access, modification, or disclosure. This includes measures such as encryption, access controls, monitoring, and logging.
Processing times, system availability, and credit ratings are also important considerations for an IS auditor, but they are not as significant as data privacy in this context. Processing times and system availability affect the performance and reliability of the application system but do not pose as significant a risk to sensitive data. Credit ratings are important for assessing the financial health of the credit card company but do not directly relate to the security of the application system or the protection of sensitive data.
