Machine shredding is the process of using a shredding machine to physically destroy the media and make the data unrecoverable. This is more effective than software formatting, which only erases the data logically and may leave traces that can be recovered by special tools1. Encrypting and destroying keys may prevent unauthorized access to the data, but it does not erase the data from the media. Wiping and rewriting three times is unnecessary and may reduce the lifespan of the media, especially for solid state drives2. Machine shredding is also recommended by various security standards and guidelines for media disposal345.

When assessing the scope of privacy concerns for an IT project, the most important factor to consider is the applicable laws and regulations. These laws and regulations define the legal requirements for data privacy and protection that the project must comply with. They can vary greatly depending on the jurisdiction and the type of data being processed, and non-compliance can result in significant penalties123. While data ownership, business requirements and data flows, and end-user access rights are also important considerations, they are typically guided by these legal requirements.

The NEXT step for the IS auditor after noting that an employee who has recently changed roles within the organization still has previous access rights should be to B. determine the reason why access rights have not been revoked. Identifying the cause of this situation is crucial for understanding whether it’s due to oversight, process gaps, or other factors. Once the reason is determined, appropriate corrective actions can be recommended to ensure that access rights are aligned with the employee’s current role and responsibilities1.

 Implementing solutions to correct defects is a responsibility of the development function, not the quality assurance (QA) function. The QA function should ensure that the development process follows the established standards and methodologies, and that the defects are identified and reported. The QA function should not be involved in fixing the defects, as this would compromise its independence and objectivity. The other options are valid responsibilities of the QA function, and they should not raise concern for an IS auditor. References: CISA Review Manual (Digital Version) 1, page 300.
