About IDW PS 951
IDW PS 951 is an auditing standard issued by the Institut der Wirtschaftsprüfer in Deutschland e.V. (Institute of Public Auditors in Germany), which regulates the audit of an outsourced internal control system on a service company. The subject of the audit is the description of the service-related internal control system, its control objectives and measures to fulfill these. All processes that have a direct or indirect impact on the provision of the outsourced service are considered. The standard is based on the international standard ISAE 3402 and represents its national counterpart.
