A System Audit is a thorough examination of an organization's information systems, processes, and controls. The primary goal is to assess the effectiveness, security, and compliance of these systems with established standards and regulations. This audit helps identify vulnerabilities, inefficiencies, and areas for improvement, ensuring that the systems operate optimally and securely. During a system audit, auditors may review various components, including hardware, software, data management, and user access controls. They often use frameworks like ISO 27001 or NIST guidelines to evaluate the systems. The findings from the audit can lead to recommendations for enhancing security and operational efficiency.
