The best metric to assure compliance with the policy of providing security awareness training to all new employees is the percentage of new hires that have completed the training, as this directly measures the extent to which the policy is implemented and enforced. The number of new hires who have violated enterprise security policies, the number of reported incidents by new hires, and the percentage of new hires who report incidents are not directly related to the policy, as they may depend on other factors such as the nature and frequency of threats, the effectiveness of security controls, and the reporting culture of the organization.

The most important aspect of an application development acceptance test is that user management approves the test design before the test is started, as this ensures that the test objectives, criteria, and procedures are aligned with the user requirements and expectations. The programming team's involvement in the testing process, the testing of data files for valid information before conversion, and the quality assurance (QA) team's charge of the testing process are also important, but they are not as critical as user management's approval of the test design.

The best way to evaluate the effectiveness of a new automated control is to review the written procedures that define the processes and controls. This will help the IS auditor to understand the objectives, scope, roles, responsibilities, and expected outcomes of the control. The written procedures will also provide a basis for testing the control and verifying its compliance with the audit finding recommendations. References:

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.
