CISA Exam Dumps - Certified Information Systems Auditor

Defining clear, comprehensive, and testable requirements is critical before selecting and implementing a software product. Without well-documented requirements, the risk of choosing a solution that does not align with business needs increases significantly. A support contract (C) is important for long-term use, and escrow (D) may protect against vendor insolvency, but neither ensures that the product fits the organization’s objectives. A post-implementation review (B) only evaluates success after implementation, which may be too late to correct fundamental misalignment. ISACA’s COBIT framework (BAI03 and BAI05) stresses the importance of requirements gathering as the foundation for effective solution acquisition and development.

The IS auditor’s next step after determining that many terminated users’ accounts were not disabled is to perform a review of terminated users’ account activity. This means that the IS auditor should check whether any of the terminated users’ accounts were accessed or used after their termination date, which could indicate unauthorized or fraudulent activity. The IS auditor should also assess the impact and risk of such activity on the confidentiality, integrity, and availability of IT resources and data. The other options are not as appropriate as performing a review of terminated users’ account activity, as they do not provide sufficient evidence or assurance of the extent and effect of the problem. References: CISA Review Manual, 27th Edition, page 240

 The best evidence that adequate resources are now allocated to successfully recover the systems is a service level agreement (SLA). An SLA is a contract between a service provider and a customer that defines the scope, quality, and terms of the service delivery. An SLA should include measurable and verifiable indicators of the service performance, such as availability, reliability, capacity, security, and recovery. An SLA should also specify the roles, responsibilities, and expectations of both parties, as well as the remedies and penalties for non-compliance. An SLA can help to ensure that the third-party vendor has allocated sufficient hardware and other resources to meet the recovery objectives and requirements of the organization. References:

CISA Questions, Answers and Explanations Database

Comprehensive and Detailed in-Depth Explanation:

Implementing edit checks ensures data validity and integrity by verifying inputs and reducing inconsistencies in the database.

Updating the data dictionary (Option A) does not resolve inconsistency issues. Data modeling (Option C) and training (Option D) are less relevant to addressing data accuracy directly.

When an IS auditor discovers a security weakness in the database configuration, the next course of action should be to identify existing mitigating controls. This involves assessing whether any controls are already in place to address the weakness and mitigate the risk. Understanding the current state of controls helps the auditor determine the severity of the issue and whether additional corrective actions are necessary1. References: 1(https://www.isaca.org/resources/insights-and-expertise/audit-programs-and-tools)
