CISA Exam Dumps - Certified Information Systems Auditor

The best source of information for an IS auditor to use as a baseline to assess the adequacy of an organization’s privacy policy is the local privacy standards and regulations. Privacy standards and regulations are legal requirements that specify how personal data should be collected, processed, stored, shared, and disposed of by organizations. By using local privacy standards and regulations as a baseline, the IS auditor can ensure that the organization’s privacy policy complies with the applicable laws and protects the rights and interests of data subjects. Historical privacy breaches and related root causes, globally accepted privacy best practices, and benchmark studies of similar organizations are useful sources of information for improving an organization’s privacy policy, but they are not as authoritative and relevant as local privacy standards and regulations. References: CISA Review Manual (Digital Version): Chapter 2 - Governance and Management of Information Technology

Clustering is a technique that groups multiple servers or nodes together to act as one system, providing high availability, scalability, and load balancing for applications or services. Clustering can improve system resiliency, which is the ability of a system to withstand or recover from failures or disruptions without compromising its functionality or performance. Clustering can achieve this by providing redundancy and fault tolerance for critical components or processes, enabling automatic failover and recovery in case of node failures, distributing workload among multiple nodes to avoid overloading or bottlenecks, and allowing dynamic addition or removal of nodes to meet changing demand or capacity needs. Clustering may also decrease system response time by improving performance and efficiency through load balancing and parallel processing, but this is not its primary purpose. Clustering may facilitate faster backups by enabling concurrent backup operations across multiple nodes, but this is not its main benefit. Clustering may improve the recovery time objective (RTO), which is the maximum acceptable time for restoring a system or service after a disruption, by reducing the downtime and data loss caused by failures, but this is not the best reason for using clustering, as there may be other factors that affect the RTO, such as backup frequency, recovery procedures, and testing methods. 

The most critical finding when reviewing an organization’s information security management is no periodic assessments to identify threats and vulnerabilities. Periodic assessments are essential for ensuring that the organization’s information security policies, procedures, standards, and controls are aligned with the current and emerging risks and threats that may affect its information assets. Without periodic assessments, the organization may not be aware of its actual security posture, gaps, or weaknesses, and may not be able to take appropriate measures to mitigate or prevent potential security incidents. No dedicated security officer, no official charter for the information security management system, and no employee awareness training and education program are also findings that may indicate some deficiencies in the organization’s information security management, but they are not as critical as no periodic assessments to identify threats and vulnerabilities. References: ISACA CISA Review Manual 27th Edition, page 343.

 The best way to ensure payment transaction data is restricted to the appropriate users is implementing role-based access at the application level. Role-based access is a method of access control that assigns permissions or privileges to users based on their roles or functions within an organization or system. Role-based access can help ensure that payment transaction data is restricted to the appropriate users, by allowing only authorized users who have a legitimate need or purpose to access or use the payment transaction data, and preventing unauthorized or unnecessary access or use by other users. Implementing two-factor authentication is a possible way to enhance the security and verification of user identities, but it is not the best way to ensure payment transaction data is restricted to the appropriate users, as it does not define what permissions or privileges users have on the payment transaction data. Restricting access to transactions using network security software is a possible way to protect the network communication and transmission of payment transaction data, but it is not the best way to ensure payment transaction data is restricted to the appropriate users, as it does not specify what actions or operations users can perform on the payment transaction data. Using a single menu for sensitive application transactions is a possible way to simplify the user interface and navigation of payment transaction data, but it is not the best way to ensure payment transaction data is restricted to the appropriate users, as it does not limit what users can access or use the payment transaction data. 

 Developing the CSA questionnaire is an activity that would allow an IS auditor to maintain independence while facilitating a control self-assessment (CSA). An IS auditor can design and provide a CSA questionnaire to help the business units or process owners to evaluate their own controls and identify any issues or improvement opportunities. This will enable an IS auditor to support and guide the CSA process without compromising their objectivity or independence. The other options are activities that would impair an IS auditor’s independence while facilitating a CSA, as they involve implementing, completing, or developing remediation actions for control issues. References:

 The results of the previous audit are an important source of information for an IS auditor to consider when performing the risk assessment prior to an audit engagement, as they can provide insights into the current state and performance of the auditee, identify any issues or gaps that need to be followed up or addressed, and highlight any areas that require special attention or focus. The design of controls is an important factor to evaluate during an audit engagement, but it is not the most important thing to consider when performing the risk assessment prior to an audit engagement, as it does not reflect the actual implementation or effectiveness of the controls. Industry standards and best practices are useful benchmarks or guidelines for an IS auditor to compare or measure against during an audit engagement, but they are not the most important thing to consider when performing the risk assessment prior to an audit engagement, as they may not be applicable or relevant to the specific context or objectives of the auditee. The amount of time since the previous audit is a relevant criterion to determine the frequency or timing of an audit engagement, but it is not the most important thing to consider when performing the risk assessment prior to an audit engagement, as it does not indicate the level or nature of risk associated with the auditee. 

The most important determining factor when establishing appropriate timeframes for follow-up activities related to audit findings is the remediation dates included in management responses. The IS auditor should ensure that the follow-up activities are aligned with the agreed-upon action plans and deadlines that management has committed to in response to the audit findings. The follow-up activities should verify that management has implemented the corrective actions effectively and in a timely manner, and that the audit findings have been resolved or mitigated.

The other options are less important factors for establishing timeframes for follow-up activities:

Availability of IS audit resources. This is a practical factor that may affect the scheduling and execution of follow-up activities, but it should not override the priority and urgency of verifying management’s corrective actions.

Peak activity periods for the business. This is a factor that may affect the availability and cooperation of auditees during follow-up activities, but it should not delay or postpone the verification of management’s corrective actions beyond reasonable limits.

Complexity of business processes identified in the audit. This is a factor that may affect the scope and depth of follow-up activities, but it should not affect the timeframe for verifying management’s corrective actions.

The best source of information for IT management to estimate resource requirements for future projects is the records of actual time spent on projects. This data can provide a realistic and reliable basis for forecasting future resource needs based on historical trends and patterns. The records of actual time spent on projects can also help IT management to identify any gaps or inefficiencies in resource allocation and utilization. The human resources (HR) sourcing strategy is not a good source of information for estimating resource requirements for future projects, as it may not reflect the actual demand and availability of IT resources. The peer organization staffing benchmarks are not a good source of information for estimating resource requirements for future projects, as they may not account for the specific characteristics and needs of each organization. The budgeted forecast for the next financial year is not a good source of information for estimating resource requirements for future projects, as it may not be based on accurate or realistic assumptions. References:
