Once a scope is determined, an auditor will be provided with a contact for the review. In some organizations, the role of audit liaison is formally assigned. This role often falls to an information security professional, but there is no expectation on the part of audit that it would be someone in security. By default, it would be the highest ranking person in the IT management chain whose responsibilities fully cover the systems within the scope of the audit. This contact will be requested to provide background information on the systems that an auditor can use to plan the audit. Policies, architecture diagrams, systems manuals, and other sorts of documentation will often be requested in advance of an audit.
