CISA Exam Dumps - Certified Information Systems Auditor

The major concern with the situation where security incidents are resolved and closed, but root causes are not investigated, is that vulnerabilities have not been properly addressed. Vulnerabilities are weaknesses or gaps in the security posture of an organization that can be exploited by threat actors to compromise its systems, data, or operations. If root causes are not investigated, vulnerabilities may remain undetected or unresolved, allowing attackers to exploit them again or use them asentry points for further attacks. This can result in repeated or escalated security incidents that can cause more damage or disruption to the organization.

The other options are not as major as the concern about vulnerabilities, but rather secondary or related issues that may arise from the lack of root cause analysis. Abuses by employees have not been reported is a concern that may indicate a lack of awareness, accountability, or monitoring of insider threats. Lessons learned have not been properly documented is a concern that may indicate a lack of improvement, learning, or feedback from security incidents. Security incident policies are out of date is a concern that may indicate a lack of alignment, review, or update of security incident processes.

 The most effective way for an organization to help ensure agreed-upon action plans from an IS audit will be implemented is to ensure ownership is assigned. This means that the management of the audited area should accept responsibility for implementing the action plans and report on their progress and completion to the audit committee or senior management. This will ensure accountability, commitment, and follow-up for the audit recommendations34. References: 3: CISA ReviewManual (Digital Version), Chapter 1: The Process of Auditing Information Systems, Section 1.6: Reporting, page 41 4: CISA Online Review Course, Module 1: The Process of Auditing Information Systems, Lesson 1.6: Reporting

 The most effective control to protect information assets in a data center from theft by a vendor is to monitor and restrict vendor activities. A vendor may have legitimate access to the data center for maintenance or support purposes, but they may also have malicious intentions or be compromised by an attacker. By monitoring and restricting vendor activities, the organization can ensure that the vendor only performs authorized tasks and does not access or tamper with sensitive data or equipment. Issuing an access card to the vendor, concealing data devices and information labels, and restricting use of portable and wireless devices are also useful controls, but they are not as effective as monitoring and restricting vendor activities in preventing theft by a vendor. References:

The best evidence that an organization’s IT strategy is aligned to its business objectives is that the IT strategy is approved by executive management. This implies that the IT strategy has been reviewed and validated by the senior leaders of the organization, who are responsible for setting and overseeing the business objectives. The IT strategy may be modified inresponse to organizational change, based on IT operational best practices, or have significant impact on the business strategy, but these are not sufficient indicators of alignment without executive approval. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.1

 Adequate action taken for noncompliance with the service level agreement (SLA) provides the best evidence that outsourced provider services are being properly managed. This shows that the organization is monitoring the performance of the provider and enforcing the terms of the SLA.

The other options are not as convincing as evidence of proper management. Option A, the SLA includes penalties for non-performance, is a good practice but does not guarantee that the penalties are actually applied or that the performance is satisfactory. Option C, the vendor provides historical data to demonstrate its performance, is not reliable because the data may be biased or inaccurate. Option D, internal performance standards align with corporate strategy, is irrelevant to the question of outsourced provider management.

The best reason to implement a data retention policy is to limit the liability associated with storing and protecting information. A data retention policy is a document that defines how long data should be kept by an organization and how they should be disposed of when they are no longer needed. A data retention policy should comply with the applicable laws and regulations that govern the data retention requirements and obligations of organizations, such as tax laws, privacy laws, or industry standards4. Implementing a data retention policy can help to limit the liability associated with storing and protecting information by reducing the amount of data that need to be stored and secured, minimizing the risk of data breaches or leaks, ensuringcompliance with legal or contractual obligations, and avoiding potential fines or penalties for non-compliance5. The other options are less relevant or incorrect because:

B. Documenting business objectives for processing data within the organization is not a reason to implement a data retention policy, as it is more related to data governance than data retention. Data governance refers to the policies, procedures, and controls that define how data are collected, used, managed, and shared within an organization. Data governance helps to ensure that data are aligned with business objectives and support decision making6.

C. Assigning responsibility and ownership for data protection outside IT is not a reason to implement a data retention policy, as it is more related to data accountability than data retention. Data accountability refers to the identification and assignment of roles and responsibilities for data protection among different stakeholders within an organization. Data accountability helps to ensure that data are handled appropriately and securely by authorized parties7.

D. Establishing a recovery point objective (RPO) for disaster recovery procedures is not a reason to implement a data retention policy, as it is more related to data backup than data retention. Data backup refers to the process of creating copies of data that can be restored in case of data loss or corruption. Data backup helps to ensure that data are available and recoverable in case of disaster8. RPO is a measure of the maximum amount of data that canbe lost or acceptable in case of disaster9. References: Data Retention Policy - ISACA, Data Retention - ISACA, Data Governance - ISACA, Data Accountability - ISACA, Data Backup - ISACA, Recovery Point Objective - ISACA

 The finding that should be the IS auditor’s greatest concern is that the data model is not clearly documented. A data model is a representation of the structure, relationships, and constraints of the data used by an application. It is a vital component of the software development process, as it helps to ensure the accuracy, consistency, and quality of the data1. A clear and comprehensive documentation of the data model is essential for the maintenance and support of the application, as it facilitates the understanding, modification, and troubleshooting of the data and the application logic2.

If the organization plans to bring the support and future maintenance of the application back in-house, it will need to have access to the data model documentation from the vendor. Without it, the organization may face difficulties in transferring the knowledge and skills from the vendor to the in-house team, as well as in adapting and enhancing the application to meet changing businessneeds and requirements3. The lack of data model documentation may also increase therisk of errors, inconsistencies, and inefficiencies in the data and the application performance2.

The other findings are not as concerning as the lack of data model documentation, because they do not directly affect the quality and maintainability of the application. The cost of outsourcing is lowerthan in-house development is a benefit rather than a risk for the organization, as it implies that outsourcing has helped to save time and money for the organization4. The vendor development team is located overseas is a common practice in outsourcing, and it does not necessarily imply a lower quality or a higher risk of the application. However, it may pose some challenges in terms of communication, coordination, and cultural differences, which can bemanaged by establishing clear expectations, roles, and responsibilities, as well as using effective tools and methods for communication and collaboration5. A training plan for business users has not been developed is a gap that should be addressed by the organization before deploying the application, as it may affect the user acceptance and satisfaction of the application. However, it does not directly impact the quality or maintainability of the application itself. References:

The mitigating factor that would most significantly minimize the impact of not renewing IT risk acceptances in a timely manner is having documented compensating controls over the business processes. Compensating controls are alternative controls that reduce or eliminate the risk when the primary control is not feasible or cost-effective. The other factors, such as previous approval by senior management, unchanged business environment, and small percentage of issues, do not mitigate the risk as effectively as compensating controls. References: ISACA CISA Review Manual 27th Edition Chapter 1
