Exam CISA Topic 5 Question 737 Discussion

The best recommendation for an organization that does not have a process to identify and correct records that do not get transferred to the receiving system is to implement software to perform automatic reconciliations of data between systems. This will ensure that the data integrity and completeness are maintained and that any errors or discrepancies are detected and resolved in a timely manner. Enabling encryption, decryption, and electronic signing of data files may enhance the data security and authenticity, but not the data accuracy or consistency. Having coders perform manual reconciliation of data between systems may be prone to human errors and inefficiencies. Automating the transfer of data between systems as much as feasible may reduce the chances of data loss or corruption, but not eliminate them completely.
