The metric that best indicates the effectiveness of awareness training is the number of users reporting receipt of the email to the information security team. This shows that the users are able to recognize and report a phishing email, which is a common social engineering technique used by attackers to trick users into revealing sensitive information or installing malicious software. The other metrics do not demonstrate a high level of security awareness, as they either ignore, follow, or forward the phishing email, which could expose the organization to potential risks.Reference:CISA Review Manual, 27th Edition, page 326

Moving validation controls from the server side into the browser would most likely increase the risk of a successful attack by structured query language (SQL) injection. SQL injection is a technique that exploits a security vulnerability in an application's database layer by inserting malicious SQL statements into user input fields. Validation controls are used to check and filter user input before sending it to the database. If these controls are moved to the browser, they can be easily bypassed or modified by an attacker, who can then execute arbitrary SQL commands on the database.Reference:CISA Review Manual, 27th Edition, page 361

The best way to ensure the quality and integrity of test procedures used in audit analytics is to centralize procedures and implement change control. Centralizing procedures means storing them in a common repository that can be accessed and updated by authorized users. Change control means implementing a process for tracking, reviewing, approving, and documenting any changes made to the procedures. This ensures that the procedures are consistent, accurate, reliable, and secure.Reference:CISA Review Manual, 27th Edition, page 401

The auditor's best action when IT management provides suitable evidence for a control that had been concluded as ineffective is to re-perform the audit before changing the conclusion. This means that the auditor should verify the validity, completeness, and timeliness of the evidence provided by IT management and test the effectiveness of the new control in meeting the audit objectives. The auditor should not change the conclusion based on evidence provided by IT management without re-performing the audit, as this could compromise the auditor's independence and objectivity. The auditor should also not explain to IT management that the new control will be evaluated during follow-up or add comments about the action taken by IT management in the report, as these actions do not address the original audit finding.Reference:CISA Review Manual, 27th Edition, page 439

The most effective way to minimize downtime during system conversions is to use a parallel run. A parallel run is a method of system conversion where both the old and new systems operate simultaneously for a period of time until the new system is verified to be functioning correctly. This reduces the risk of errors, data loss, or system failure during conversion and allows for a smooth transition from one system to another.Reference:CISA Review Manual, 27th Edition, page 467

Mapping IT processes to roles is an activity that provides an IS auditor with the most insight regarding potential single person dependencies that might exist within the organization. Single person dependencies occur when only one person has the knowledge, skills, or access rights to perform a critical IT function. Mapping IT processes to roles can help to identify such dependencies and assess their impact on the continuity and security of IT operations. The other activities do not provide as much insight into single person dependencies, as they do not show the relationship between IT processes and roles.Reference:CISA Review Manual, 27th Edition, page 94

Decreased time for incident resolution is the best indicator that an incident management process is effective. Incident management is a process that aims to restore normal service operation as quickly as possible after an incident, which is an unplanned interruption or reduction in quality of an IT service. Decreased time for incident resolution means that the incident management process is able to identify, analyze, respond to, and resolve incidents efficiently and effectively. The other indicators do not necessarily reflect the effectiveness of the incident management process, as they may depend on other factors such as the nature, frequency, and severity of incidents.Reference:CISA Review Manual, 27th Edition, page 372

The system only allows payments to vendors who are included in the system's master vendor list is an example of a preventative control in an accounts payable system. A preventative control is a control that aims to prevent errors or irregularities from occurring in the first place. By restricting payments to vendors who are authorized and verified in the master vendor list, the system prevents unauthorized or fraudulent payments from being made. The other options are examples of other types of controls, such as backup (recovery), reconciliation (detective), and communication (directive) controls.Reference:CISA Review Manual, 27th Edition, page 223

The most important thing to determine next after concluding that an organization has a quality security policy is whether the policy is well understood by all employees. A security policy is a document that defines the objectives, scope, roles, responsibilities, and rules for information security within an organization. A quality security policy is one that is clear, concise, consistent, comprehensive, and aligned with business goals and requirements. However, a quality security policy is useless if it is not well understood by all employees who are expected to comply with it. Therefore, the IS auditor should assess the level of awareness and understanding of the security policy among employees and identify any gaps or issues that need to be addressed. The other options are not as important as ensuring that the security policy is well understood by all employees, as they do not directly affect the implementation and effectiveness of the security policy.Reference:CISA Review Manual, 27th Edition, page 317
