The first task that an IS auditor should complete during the preliminary planning phase of a database security review is to determine which databases will be in scope. The scope defines the boundaries and objectives of the audit, as well as the resources, time, and budget required. The IS auditor should identify the databases that are relevant to the audit based on factors such as their criticality, risk, complexity, size, type, location, and ownership. The IS auditor should also consider the regulatory, contractual, and organizational requirements that apply to the databases. By defining the scope clearly and accurately, the IS auditor can ensure that the audit is focused, feasible, and effective. References:
