Asking management why the regulatory changes have not been included is the first thing that an IS auditor should do during the planning stage of a compliance audit. An IS auditor should inquire about the reasons for not updating the inventory of compliance requirements with recent regulatory changes related to managing data risk. This will help the IS auditor to understand whether there is a gap in awareness, communication, or implementation of compliance obligations within the organization. The other options are not the first things that an IS auditor should do, but rather possible subsequent actions that may depend on management's response. References:

The greatest concern for an IS auditor reviewing data conversion and migration during the implementation of a new application system is unauthorized data modifications occurred during conversion. Unauthorized data modifications are changes or alterations to data that are not authorized, intended, or expected, such as due to errors, fraud, or sabotage. Unauthorized data modifications occurred during conversion can compromise the accuracy, completeness, andintegrity of the data being converted and migrated to the new application system, and may result in data loss, corruption, or inconsistency. The other options are not as concerning as unauthorized data modifications occurred during conversion in reviewing data conversion and migration during the implementation of a new application system, as they do not affect the accuracy, completeness, or integrity of the data being converted and migrated. Data conversion was performed using manual processes is a possible factor that may increase the risk or complexity of data conversion and migration, but it does not necessarily imply that unauthorized data modifications occurred during conversion. Backups of the old system and data are not available online is a possible factor that may affect the availability or accessibility of the old system and data for backup or recovery purposes, but it does not imply that unauthorized data modifications occurred during conversion. The change management process was not formally documented is a possible factor that may affect the quality or consistency of the change management process for implementing the new application system, but it does not imply that unauthorized data modifications occurred during conversion.

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.

The best way to determine whether IT investments are meeting business objectives is to compare the realized return on investment (ROI) versus the projected ROI (Option B). This approach measures actual performance against planned expectations.
ISACA CISA Reference: The ISACA IT Governance framework emphasizes performance measurement through ROI analysis, ensuring IT investments align with strategic objectives.
Risk Implication: If actual ROI is lower than projected, this may indicate ineffective investment decisions, poor execution, or misalignment with business goals.
Alternative Choices:
Option A: Break-even analysis only determines when an investment recoups its costs but does not measure performance against business objectives.
Option C: Budgeted versus actual spend assesses financial discipline but does not indicate business impact.
Option D: Industry average ROI provides benchmarking but does not assess internal goal achievement.
