The assurances provided by an assurance protocol for any information system (IS), extend only as much as the integrity of the assurance protocol itself. The integrity of the assurance protocol is negatively influenced by a) the complexity of the assurance protocol, and b) the complexity of the platform on which the assurance protocol is executed. This paper outlines a holistic Mirror Network (MN) framework for assuring information systems that seeks to minimize both complexities. The MN framework is illustrated using a generic cloud file storage system as an example IS.
