# Auditing

The OneSpan Authentication Server audit system enables you to audit the operations that OneSpan Authentication Server performs and provides high-level details about these operations. The audit system consists of a number of auditing modules that save audit messages to a specific format (e.g. text file or database), and the Audit Viewer application, which can open, display, and filter audit messages from various sources.
