The Liberty Audit feature is used to report and track auditable events to ensure the integrity of your system. The Liberty Audit feature introduces an infrastructure which serves two purposes: - Confirming the effectiveness and integrity of the existing configuration - Identifying areas where improvement to the configuration may be needed The Liberty Audit feature has the ability to capture the following auditable events: - Basic authentication - Start and stop of the Audit service - Form login - Client certificate login - Servlet runAs delegation - Form logout - Servlet 3.0 login, logout and authenticate APIs The Liberty Audit feature supports the Cloud Auditing Data Federation (CADF) event model. The CADF model describes a data model and associated schema definitions for an audit event. The feature provides a default implementation, the AuditFileHandler, which emits human-readable audit records to a file-based log. Each audit record is emitted in JSON format.
