Audit Trail
What is Audit Trail?
An audit trail is a chronological record that provides documentary evidence of the sequence of activities or transactions that have affected a specific operation, procedure, or event.
It allows for the tracking of changes made to data, ensuring transparency, accountability, and compliance with regulatory standards. By providing a time-stamped sequence of events or transactions, the audit trail details when and by whom actions were performed, ensuring that all changes or transactions are traceable to specific individuals or systems. This fosters responsibility and transparency, helps organizations adhere to industry regulations and standards, and maintains the integrity of data by recording all modifications, thereby preventing unauthorized or unintentional alterations.
Types of Audit Trail with Example
1. User Activity Audit Trail:
Tracks all actions performed by users within a system, such as logging in, accessing files, or making changes to data.
Example: A user activity audit trail might show that User A logged in at 9:00 AM, accessed the payroll database at 9:15 AM, and modified employee records at 9:30 AM.
2. Transaction Audit Trail:
Records all financial transactions or changes in a financial system, ensuring that each step of the transaction process is documented.
Example: A transaction audit trail could document the approval process for a purchase order, showing each step from the initial request to the final payment.
3. System-Level Audit Trail:
Monitors changes at the system level, such as configuration changes, software updates, or security settings adjustments.
Example: A system-level audit trail might record that an administrator updated the system firewall settings at 10:00 AM and installed a software patch at 10:30 AM.
4. Compliance Audit Trail:
Specifically tracks activities related to compliance with legal or regulatory requirements, such as data handling practices or security protocols.
Example: A compliance audit trail could document the steps taken to secure customer data in line with GDPR requirements, including encryption actions and access permissions.
