Asking management why the regulatory changes have not been included is the first thing that an IS auditor should do during the planning stage of a compliance audit. An IS auditor should inquire about the reasons for not updating the inventory of compliance requirements with recent regulatory changes related to managing data risk. This will help the IS auditor to understand whether there is a gap in awareness, communication, or implementation of compliance obligations within the organization. The other options are not the first things that an IS auditor should do, but rather possible subsequent actions that may depend on management's response.
