CISA Exam Dumps - Certified Information Systems Auditor

 The greatest concern for an IS auditor when evaluating an organization’s IT strategy and plans is that IT is not engaged in business strategic planning, as this indicates a lack of alignment between IT and business objectives, which could result in inefficient and ineffective use of IT resources and capabilities. The absence of a defined IT security policy, the nondistribution of business strategy meeting minutes, and the inadequate documentation of IT strategic planning are also issues that should be addressed by an IS auditor, but they are not as significant as IT’s noninvolvement in business strategic planning. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.1

 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. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.7

Parallel processing is a system implementation approach that involves running the new system and the old system simultaneously for a period of time until the new system is verified and accepted. The primary advantage of parallel processing is that it provides assurance that the new system meets performance requirements and produces the same or better results as the old system. Parallel processing also minimizes the risk of system failure and data loss, as the old system can be used as a backup or fallback option in case of any problems with the new system.

The IS auditor’s best recommendation is to ensure that programmers cannot access code after the completion of program edits. This is because programmers who have access to code after editing may introduce unauthorized or malicious changes that could compromise the security, functionality, or performance of the application. By restricting access to code after editing, the organization can ensure that only authorized and tested code is released into production, and prevent any tampering or reoccurrence of the same issue.

If an IS audit reveals that an organization is not proactively addressing known vulnerabilities, the IS auditor should recommend that the organization assess the security risks to the business first, as this would help to prioritize the vulnerabilities based on their impact and likelihood, and determine the appropriate mitigation strategies. Verifying the disaster recovery plan (DRP) has been tested, ensuring the intrusion prevention system (IPS) is effective, and confirming the incident response team understands the issue are important steps, but they are not as urgent as assessing the security risks to the business. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.6

 Version control is a process of managing changes to an application or a document. It ensures that only the latest approved version of the application is used by end-users, which reduces the risk of errors, inconsistencies, and unauthorized modifications. Version control also allows tracking the history of changes and restoring previous versions if needed. 

 The IS auditor’s independence would be most likely impaired if they implemented a specific control during the development of an application system. This is because the IS auditor would be auditing their own work, which creates a self-review threat that could compromise their objectivity and impartiality. The IS auditor should avoid participating in any operational or management activities that could affect their ability to perform an unbiased audit. The other options do not pose a significant threat to the IS auditor’s independence, as long as they follow the ethical standards and guidelines of the profession.

The most effective way to detect an intrusion attempt is to periodically review log files, which record the activities and events on a system or network. Log files can provide evidence of unauthorized access attempts, malicious activities, or system errors. Configuring the router as a firewall, using smart cards with one-time passwords, and installing biometrics-basedauthentication are preventive controls that can reduce the likelihood of an intrusion, but they do not detect it. References: ISACA CISA Review Manual 27th Edition, page 301
