The auditor’s greatest concern when reviewing data inputs from spreadsheets into the core finance system would be undocumented code that formats data and transmits directly to the database. This is because undocumented code can introduce errors, inconsistencies, and security risks in the data processing and reporting. Undocumented code can also make it difficult to verify the accuracy, completeness, and validity of the data inputs and outputs, as well as to trace the source and destination of the data. Undocumented code can also violate the principles of segregation of duties, as the same person who creates the code may also have access to the data and the database.

The other options are not as concerning as undocumented code, although they may also pose some risks. A lack of complete inventory of spreadsheets and inconsistent file naming may make it challenging to identify and locate the relevant spreadsheets, but they do not directly affect the quality or integrity of the data inputs. The department data protection policy not being reviewed or updated for two years may indicate a lack of awareness or compliance with the current data protection regulations, but it does not necessarily imply that the data inputs are compromised or inaccurate. Spreadsheets being accessible by all members of the finance department may increase the risk of unauthorized or accidental changes to the data, but it can be mitigated by implementing access controls, password protection, and audit trails.

Among the options provided, fingerprint scanning has the highest rate of false negatives. False negatives occur when a biometric system fails to recognize an authentic individual. Factors such as skin conditions (wet, dry, greasy), finger injuries, and inadequate scanning can contribute to false negatives in fingerprint scanning1. In comparison, iris recognition23, face recognition45, and retina scanning67 generally have lower rates of false negatives.

 A SQL injection attack is a type of attack that targets security vulnerabilities in web applications to gain access to data sets. A SQL injection attack exploits a flaw in the web application code that allows an attacker to inject malicious SQL statements into the input fields or parameters of the web application. These SQL statements can then execute on the underlying database server and manipulate or retrieve sensitive data from the database. A SQL injection attack can result in data theft, data corruption, unauthorized access, denial of service or even complete takeover of the database server. A denial of service (DOS) attack is a type of attack that aims to disrupt the availability or functionality of a web application or a network service by overwhelming it with excessive requests or traffic. A phishing attack is a type of attack that uses deceptive emails or websites to trick users into revealing their personal or financial information or credentials. A rootkit is a type of malware that hides itself from detection and grants unauthorized access or control over a compromised system. References: IS Audit and Assurance Tools and Techniques, CISA Certification | Certified Information Systems Auditor | ISACA

 Enterprise architecture (EA) is the most helpful to an IS auditor reviewing the alignment of planned IT budget with the organization’s goals and strategic objectives. EA is a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy1. EA provides a blueprint for an effective IT strategy and guides the controlled evolution of IT in a way that delivers business benefit in a cost-effective way2. By reviewing the EA, the IS auditor can evaluate how well the planned IT budget supports the business vision, strategy, objectives, and capabilities of the organization.

The other options are not as helpful as EA for reviewing the alignment of planned IT budget with the organization’s goals and strategic objectives. BIA is a process of determining the criticality of business activities and associated resource requirements to ensure operational resilience and continuity of operations during and after a business disruption3. BIA quantifies the impacts of disruptions on service delivery, risks to service delivery, and recovery time objectives (RTOs) and recovery point objectives (RPOs)3. BIA is useful for developing strategies, solutions, and plans for business continuity and disaster recovery, but it does not directly address the alignment of planned IT budget with the organization’s goals and strategic objectives. Risk assessment report is a document that contains the results of performing a risk assessment or the formal output from the process of assessing risk4. Risk assessment is a method to identify, analyze, and control hazards and risks present in a situation or a place5. Risk assessment report is useful for identifying and mitigating potential threats and issues that are detrimental to the business or an enterprise, but it does not directly addressthe alignment of planned IT budget with the organization’s goals and strategic objectives. Audit recommendations are guidance that highlights actions to be taken by management6. When implemented, process risks should be mitigated, and performance should be enhanced6. Audit recommendations are useful for improving the quality and reliability of the information system and its outputs, but they do not directly address the alignment of planned IT budget with the organization’s goals and strategic objectives. Therefore, option A is the correct answer.
