CISA Exam Dumps - Certified Information Systems Auditor

When auditing the alignment of IT to the business strategy, it is most important for the IS auditor to evaluate deliverables of new IT initiatives against planned business services. This can help the IS auditor to assess whether the IT initiatives are meeting the business needs and expectations, delivering value and benefits, and supporting the business objectives and goals. Comparing the organization’s strategic plan against industry best practice is a possible technique for auditing the alignment of IT to the business strategy, but it is not the most important thing for the IS auditor to do, as industry best practice may not be applicable or relevant to the specific context or situation of the organization. Interviewing senior managers for their opinion of the IT function is a possible technique for auditing the alignment of IT to the business strategy, but it is not the most important thing for the IS auditor to do, as senior managers’ opinions may be subjective or biased, and may not reflect the actual performance or outcomes of the IT function. Ensuring an IT steering committee is appointed to monitor new IT projects is a possible control for ensuring the alignment of IT to the business strategy, but it is not the most important thing for the IS auditor to do, as an IT steering committee may not be effective or efficient in monitoring new IT projects, and may not have sufficient authority or influence over the IT function. 

 Control self-assessment (CSA) is a technique that enables business managers and staff to assess and improve the effectiveness of their own controls and risk management processes. CSA can best enable the timely identification of risk exposure, as it allows for continuous monitoring and reporting of risks by those who are closest to the business processes and activities. External audit review, internal audit review, and stress testing are also useful methods for identifying risk exposure, but they are not as timely as CSA, as they are performed periodically or on demand by external or internal parties whomay not have as much insight into the business operations and environment. References: ISACA CISA Review Manual 27th Edition, page 95.

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

Business processes should be the primary focus of an IS auditor when developing a risk-based IS audit program, because they represent the core activities and functions of the organization that support its objectives and goals. Business processes also involve the use of IT resources and systems that may pose risks to the organization’s performance and compliance. A risk-based IS audit program should identify and assess the risks associated with the business processes and determine the appropriate audit scope and procedures to provide assurance on their effectiveness and efficiency. Portfolio management, business plans, and IT strategic plans are also relevant factors for developing a risk-based IS audit program, but they are not as important as business processes. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.2.1

 When reviewing an enterprise architecture (EA) department’s decision to change a legacy system’s components while maintaining its original functionality, an IS auditor should understand the current business capabilities delivered by the legacy system, as this would help to evaluate whether the change is justified, feasible, and aligned with the business goals and needs. The proposed network topology to be used by the redesigned system, the data flows between the components to be used by the redesigned system, and the database entity relationships within the legacy system are technical details that are less relevant for an IS auditor to understand when reviewing this decision. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

The best recommendation to mitigate the risk of data leakage from lost or stolen devices that contain confidential data is to configure them to auto-wipe after multiple failed access attempts, as this would prevent unauthorized access and erase sensitive information from the device. Requiring employees to attend security awareness training, password protecting critical data files, or enabling device auto-lockfunction are also good practices, but they may not be sufficient oreffective in preventing data leakage from lost or stolen devices. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3

The best test to provide assurance that a health care organization is handling patient data appropriately is compliance with local laws and regulations, as these are the primary sources of authority and obligation for data protection and privacy. Compliance with action plans, industry standards, or organizational policies and procedures are also important, but they may not cover all the legal requirements or reflect the currentbest practices for handling patient data. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.3

When implementing Internet Protocol security (IPsec) architecture, the servers involved in application delivery communicate via Transport Layer Security (TLS), which is a protocol that provides encryption and authentication for data transmitted over a network. IPsec operates at the network layer and provides security for IP packets, while TLS operates at the transport layer and provides security for TCP connections. Blocking authorized users from unauthorized activities, channeling access only through the public-facing firewall, and channeling access through authentication are not functions of IPsec architecture. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.2
