CISA Exam Dumps - Certified Information Systems Auditor

The best approach to optimize resources when both internal and external audit teams are reviewing the same IT general controls area is to leverage the work performed by external audit for the internal audit testing. This can avoid duplication of efforts, reduce audit costs and enhance coordination between the audit teams. The internal audit team should evaluate the quality and reliability of the external audit work before relying on it. Ensuring both the internal and external auditors perform the worksimultaneously is not an efficient use of resources, as it would create redundancy and possible interference. Requesting that the external audit team leverage the internal audit work may not be feasible or acceptable, as the external audit team may have different objectives, standards and independence requirements. Rolling forward the general controls audit to the subsequent audit year is not a good practice, as it would delay the identification and remediation of any control weaknesses in a high-risk area. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 247

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:

 The best way to ensure that a proper cutoff has been established to reinstate transactions and records to their condition just prior to a computer system failure is to use a database management system (DBMS) to dynamically back-out partially processed transactions. A DBMS is a software system that manages the creation, manipulation, retrieval, and security of data stored in a database. A DBMS can provide features such as transaction management, concurrency control, recovery management, and integrity management. A DBMS can dynamically back-out partially processed transactions by using mechanisms such as rollback segments, undo logs, or write-ahead logs. These mechanisms allow the DBMS to restore the database to a consistent state before the failure occurred. References:

The finding that should be ranked as the highest risk is that network penetration tests are not performed. Network penetration tests are simulated cyberattacks that aim to identify and exploit the vulnerabilities and weaknesses of the network security controls, such as firewalls, routers, switches, servers, and devices. Network penetration tests are essential for assessing the effectiveness and resilience of the network security posture, and for providing recommendations for improvement and remediation. If network penetration tests are not performed, the organization may not be aware of the existing or potential threats and risks to its network, and may not be able to prevent or respond to real cyberattacks, which can result in data breaches, service disruptions, financial losses, reputational damage, and legal or regulatory penalties. The other findings are also important, butnot as risky as the lack of network penetration tests, because they either do not directly affect the networksecurity controls, or they can be addressed by documentation or approval processes. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4

An appropriate role of internal audit in helping to establish an organization’s privacy program is analyzing risks posed by new regulations. A privacy program is a set of policies, procedures, and controls that aim to protect the personal data of individuals from unauthorized or unlawful collection, use, disclosure, or disposal. A privacy program should comply with the applicable laws and regulations that govern the privacy rights and obligations of individuals and organizations, such as the General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA). New regulations may introduce new requirements or changes that affect the organization’s privacy program and expose it to potential compliance risks or penalties. Therefore, internal audit can help to establish an organization’s privacy program by analyzing the risks posed by new regulations and providingassurance, advice, or recommendations on how to address them1. The other options are less appropriate or incorrect because:

B. Developing procedures to monitor the use of personal data is not an appropriate role of internal audit in helping to establish an organization’s privacy program, as it is more of a management or operational role. Internal audit should not be involved in designing or implementing the organization’s privacy program, as it would compromise its independence and objectivity. Internal audit should provide assurance on the effectiveness and efficiency of the organization’s privacy program, but not create or execute it2.

C. Defining roles within the organization related to privacy is not an appropriate role of internal audit in helping to establish an organization’s privacy program, as it is more of a governance or strategic role. Internal audit should not be involved in setting or approving the organization’s privacy strategy, objectives, or policies, as it would compromise its independence and objectivity. Internal audit should provide assurance on the alignment and compliance ofthe organization’s privacy program with its strategy, objectives, and policies, but not define or approve them2.

D. Designing controls to protect personal data is not an appropriate role of internal audit in helping to establish an organization’s privacy program, as it is more of a management or operational role. Internal audit should not be involved in designing or implementing the organization’s privacy program, as it would compromise its independence and objectivity. Internal audit should provide assurance on the adequacy and effectiveness of the organization’s privacy program, but not design or implement it2. References: ISACA Introduces New Audit Programs for Business Continuity/Disaster …, Best Practices for Privacy Audits - ISACA, ISACA Produces New Audit and Assurance Programs for Data Privacy and …

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 way to validate that appropriate security controls are in place to prevent data loss is to review compliance with data loss and applicable mobile device user acceptance policies. This will ensure that the organization has established clear rules and guidelines for employees to follow when connecting their personal devices to company-owned computers. A walk-through, a DLP tool configuration, and a security awareness training are not sufficient to validate the effectiveness of the controls, as they may not cover all possible scenarios and risks. References: IT Audit Fundamentals Certificate Resources

This means that the organization should obtain the source code from the escrow agent and compare it with the current version of the application that they are using. The organization should then identify and apply any changes or updates that are missing or different in the escrow version, so that it matches the current version. This way, the organization can ensure that they have a complete and accurate copy of the source code that reflects their current needs and requirements.

Bringing the escrow version up to date can help the organization to avoid or reduce the risks and costs associated with using an outdated or incompatible version of the source code. For example, an older version of the source code may have bugs, errors, or vulnerabilities that could affect the functionality, security, or performance of the application. An older version of the source code mayalso lack some features, enhancements, or integrations that could improve the usability, efficiency, or value of the application. An older version of the source code may also not comply with some standards, regulations, or contracts that could affect the quality, reliability, or legality of the application1.

The other options are not as good as bringing the escrow version up to date for the organization. Option A, analyzing a new application that meets the current requirements, is a possible option but it may be more time-consuming, expensive, and risky than updating the existing application. The organization may have to go through a complex and lengthy process of selecting, acquiring, implementing, testing, and migrating to a new application, which could disrupt their operations and performance. The organization may also have to deal with compatibility, interoperability, or data quality issues when switching to a new application2. Option B, performing an analysis to determine the business risk, is a necessary step but not a recommendation for the organization. The organization should already be aware of the business risk of using an application whose vendor has gone out of business and whose escrow has an older version of the source code. The organization should focus on finding and implementing a solution to mitigate or eliminate this risk3. Option D, developing a maintenance plan to support the application using the existing code, is not a feasible option because it assumes that the organization has access to the existing code. However, this is not the case because the vendor has gone out of business and the escrow has an older version of the source code. The organization cannot support or maintain an application without having a complete and accurate copy of its source code.
