This document provides an overview of evaluating risks associated with outsourcing to vendor organizations. It discusses classifying vendor risks such as operational, reputation, strategic, compliance, financial, and support risks. It also covers rights to audit vendor organizations and mechanisms for assessing internal controls at service organizations, including SAS 70, Shared Assessments, and ISAE 3402 reports which are issued by independent auditors or assessment firms. The document uses a case study of JP Morgan's outsourcing agreement with IBM to illustrate key considerations around understanding controls at an outsourced vendor.
