What Is Audit Trail?
An audit trail is a methodical report of everything done, processed, or altered in a system for transparency, accountability, and security. It captures a chronological log of events that tracks who made a change, when it occurred, and the modifications made. Audit trails find common applications in financial systems, cybersecurity, medicine, and regulatory compliance auditing to catch errors, prevent fraud, and ensure regulatory compliance.
Types Of Audit Trails
- Financial Audit Trail: A financial audit trail includes all financial dealings, such as payments, receipts, and journal postings. With a correct history of financial activity, businesses can conclude fraud, discrepancies, and mistakes, improving financial integrity.
- IT & Security Audit Trail: An IT and security audit trail tracks system activity such as user login, data access, file changes, and system updates. Companies utilise IT audit trails to enhance cybersecurity, secure sensitive data, and meet data protection regulations like GDPR and HIPAA.
- Operational Audit Trail: As the complexities in the business environment evolve, the need for streamlining business activities and processes arises at the core operational level. As the scope of inadvertent errors and frauds grows, business processes and activities need to be recorded and documented. Another operational audit trail has satisfied this requirement. This helps the business review its processes, thereby identifying process gaps, instances of errors and fraud, and locating places where efficiency can be improved.
- Compliance Audit Trail: A compliance audit trail maintains that organisations comply with industry regulations, legal standards, and internal policies. It is applied extensively in healthcare, finance, and manufacturing to prove compliance with laws like the Sarbanes-Oxley Act (SOX), HIPAA, and ISO standards. Compliance audit trails assist companies in evading legal sanctions, enhancing governance, and establishing trust with stakeholders.
- Manufacturing & Supply Chain Audit Trail: Manufacturing and supply chain audit trails follow the movement of products, production activities, inventory control, and logistics.
