Deleting Audit Data

Audit data that is older than a given period, defined by your organization, or that is no longer required for the original purpose, can be deleted from the OneSpan Authentication Server audit database. This can be done via the OneSpan Authentication Server Maintenance Wizard, or via the Administration Web Interface and the Delete Audit Data Wizard.

The Audit Message Import/Export wizard allows you to import audit data from one source and re-import it to a text file or ODBC database. This wizard is launched from the main interface of the Maintenance Wizard.

With the Delete Audit Data wizard you can either delete audit records immediately, or schedule a task for the deletion. You can also configure this to be a recurring task and delete audit records at regular intervals.

Depending on the used DBMS, deleting audit data does not automatically or immediately release the consumed disk space. For instance, in case of MariaDB the database engine marks the space as available for reuse, but does not effectively reduce the disk space used by the database files (unless you are using database partitioning). This space is reclaimed by the database over time when new data is written.

For more information about task management and more detailed instructions for audit message export and task-based erasure of audit data, refer to the OneSpan Authentication Server Administrator Guide.
