How does the system maintain an audit trail of security maintenance performed (user account and access rights management, security settings configuration, encryption key management, etc.)?

Configuration changes on the Industrial App Store (e.g. assignment of a user to a group, changes in organisation trust settings) are recorded and visible to Organisation Administrator users for the affected organisation.

Dynamic calculation tags record metadata such as the identity of the creator, last modified, and the date and time that the calculations was created or last modified at.

Data source configuration changes on an App Store Connect fall under the purview of the organisation's own IT change management, since these must be performed locally on the App Store Connect machine.
