Effective governance over IT infrastructure is indicated by the ability to deliver continuous, reliable performance12. This is because good governance ensures that IT investments support business objectives and produce measurable results towards achieving their strategies2. It involves implementing management and internal controls, strengthening security, financial controls, risk mitigation, and inspection and compliance obligations3. While security awareness programs, the number of servers, and the number of security incidents can be aspects of IT governance, they are not the best indicators of its effectiveness.

The greatest concern for an IS auditor reviewing a network printer disposal process is that evidence is not available to verify printer hard drives have been sanitized prior to disposal. This can expose sensitive data to unauthorized parties and cause data breaches. Disposal policies and procedures not being consistently implemented or business units being allowed to dispose printers directly to vendors are compliance issues, but not as critical as data protection. Inoperable printers being stored in an unsecured area is a physical security issue, but not as severe as data leakage. References: ISACA, CISA Review Manual, 27th Edition, 2018, page

Quality control reviews are the best way to demonstrate to senior management and the board that an audit function is compliant with standards and the code of ethics. These reviews assess the efficiency and effectiveness of the audit function, ensure compliance with audit standards and ethics, and identify areas for improvement12. While audit staff interviews, control self-assessments (CSAs), and corrective action plans can provide valuable insights, they do not offer the same level of assurance as a comprehensive quality control review12.

the need for DLP visibility in the cloud:
Verified Answer
