CISA Exam Dumps - Certified Information Systems Auditor

The finding that should be of greatest concern to the IS auditor is that user accounts are shared between users. User accounts are unique identifiers that grant access to an organization’s financial business application based on the roles and responsibilities of the users. User accounts should be individualized and personalized to ensure accountability, traceability, and auditability of user actions and transactions. User accounts should not be shared between users, because this can compromise the confidentiality, integrity, and availability of the financial data and systems, and can enable unauthorized or fraudulent activities. If user accounts are shared between users, the IS auditor may not be able to determine who performed what action or transaction, or whether the user had the appropriate authorization or approval. The other findings are also concerning, but not as much as user account sharing, because they either affect the password strength or frequency rather than the useridentity, or they relate to monitoring rather than controlling user access. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.2

The best recommendation for an IS auditor who finds that one employee has unauthorized access to confidential data is to require the business owner to conduct regular access reviews. Access reviews are periodic assessments of user access rights and permissions to ensure that they are appropriate, necessary, and aligned with the business needs and objectives. Access reviews help to identify and remediate any unauthorized, excessive, or obsolete access that could pose a security risk or violate compliance requirements. The business owner is responsible for defining and approving the access requirements for their data and ensuring that they are enforced and monitored. References:

The best indication to an IS auditor that management’s post-implementation review was effective is that lessons learned were documented and applied, as this shows that the management has identified and addressed the issues and gaps that arose during the implementation, and has improved the processes and practices for future projects. Business and IT stakeholders participating in the post-implementation review is a good practice, but it does not guarantee that the review was effective or that the outcomes were implemented. Post-implementation review being a formal phase in the system development life cycle (SDLC) is a requirement, but it does not ensure that the review was effective or that the outcomes were implemented. Internal audit follow-up being completed without any findings is a desirable result, but it does not indicate that the management’s post-implementation review was effectiveorthat the outcomes were implemented. References: CISA Review Manual (Digital Version), Chapter 3: Information Systems Acquisition, Development andImplementation, Section 3.2: Project Management Practices1

 The answer C is correct because preventive maintenance is outsourced to multiple vendors without requiring nondisclosure agreements (NDAs) would be of greatest concern to an IS auditor reviewing on-site preventive maintenance for an organization’s business-critical server hardware. This is because outsourcing preventive maintenance to multiple vendors without NDAs exposes the organization to the risk of unauthorized access, disclosure, or modification of sensitive data and information stored on the servers. NDAs are legal contracts that bind the vendors to protect the confidentiality and security of the data and information they access or handle during the preventive maintenance. Without NDAs, the vendors may not have any obligation or incentive to safeguard the data and information, and they may misuse, leak, or compromise them for malicious or commercial purposes. This could result in financial losses, reputational damage, legal liabilities, or regulatory penalties for the organization.

The other options are not as concerning as option C. Preventive maintenance costs exceed the business allocated budget (option A) is a financial issue that may affect the profitability or efficiency of the organization, but it does not directly impact the security or availability of the server hardware. Preventive maintenance has not been approved by the information system (option B) is a procedural issue that may indicate a lack of coordination or communication between the IT department and the business units, but it does not necessarily affect the quality or effectiveness of the preventive maintenance. The preventive maintenance schedule is based on mean time between failures (MTBF) parameters (option D) is a technical issue that may influence the frequency or timing of the preventive maintenance, but it does not imply any risk or deficiency in the preventive maintenance itself.

Issuing authentication tokens is the most reliable method of preventing unauthorized logon, as it provides a strong form of authentication that requires users to present something they have (the token) and something they know (the personal identification number or PIN) to access the system. Authentication tokens are physical devices that generate a one-time password or code that changes periodically and is synchronized with the authentication server. This makes it difficult for attackers to steal or guess the credentials of legitimate users. Reinforcing current security policies, limiting after-hours usage and installing an automatic password generator are not as reliable as issuing authentication tokens, as they do not provide a strong form of authentication and may still be vulnerable to unauthorized logon attempts. References:

 The greatest benefit of adopting an international IT governance framework rather than establishing a new framework based on the actual situation of a specific organization is wide acceptance by different business and support units with IT governance objectives. An international IT governance framework, such as COBIT, provides a common language and understanding for IT governance among various stakeholders, such as management, users, auditors and regulators. This facilitates alignment, communication and collaboration among them. Readily available resources, comprehensive coverage and fewer resources expended are also benefits of adopting an international IT governance framework, but they are not the greatest benefit. References: CISA Review Manual (Digital Version) , Chapter 1, Section 1.3.1.

A balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The other options are not the primary uses of a balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy.

The primary benefit of automating application testing is to provide test consistency. Automated testing can ensure that the same test cases are executed in the same manner and order every time, which can improve the reliability and accuracy of the test results. Providing more flexibility, replacing all manual test processes, and reducing the time to review code are possible benefits of automating application testing, but they are not the primary benefit. References:
