CISA Exam Dumps - Certified Information Systems Auditor

Segregation of duties (SoD) is a key internal control that aims to prevent fraud and errors by ensuring that no single individual can perform incompatible or conflicting tasks within a business process. SoD reduces the risk of unauthorized or improper transactions, manipulation of data, or misappropriation of assets.

In the accounts payable department, SoD involves separating the following functions: invoice processing, payment authorization, payment execution, and reconciliation. For example, the person who approves an invoice should not be the same person who issues the payment or reconciles the bank statement.

One of the best ways to ensure appropriate SoD within the accounts payable department is to restrict program functionality according to user security profiles. This means that each user of the accounts payable system should have a unique login and password, and should only have access to the functions that are relevant to their role and responsibilities. For instance, an invoice processor should not be able to approve payments or modify vendor records. This way, the system can enforce SoD and prevent unauthorized or fraudulent activities.

The other options are not as effective as restricting program functionality according to user security profiles. Restricting access to update programs to accounts payable staff only is a general access control measure, but it does not address the SoD issue within the accounts payable department. Including the creator’s user ID as a field in every transaction record created is a useful audit trail feature, but it does not prevent users from performing incompatible functions. Ensuring that audit trails exist for transactions is a detective control that can help identify and investigate any irregularities, but it does not prevent them from occurring in the first place.

 The greatest challenge to the alignment of business and IT is the lack of chief information officer (CIO) involvement in board meetings. The CIO is the senior executive responsible for overseeing the IT strategy, governance, and operations of the organization, and ensuring that they support the business objectives and needs. The CIO should be involved in board meetings to communicate the value and contribution of IT to the organization, to align the IT vision and direction with the business strategy and priorities, and to advocate for the IT resources and investments required to achieve the desired outcomes. The lack of CIO involvement in board meetings can result in a disconnect between business and IT, a loss of trust and confidence in IT, and missed opportunities for innovation and value creation. The other options are not as challenging as the lack of CIO involvement in board meetings, because they either do not affect the strategic alignment of business and IT, or theycanbe addressed by other means such as collaboration, negotiation, or escalation. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.1

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

The IS auditor should notify audit management of the finding first, as this is a significant issue that may affect the audit scope and objectives. The IS auditor should not notify law enforcement or require the third party to notify customers without consulting audit management first. The audit report with a significant finding should be issued after the audit is completed and the findings are validated. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 247

The best way to mitigate the risk associated with unintentional modifications of complex calculations in end-user computing (EUC) is to execute copies of EUC programs out of a secure library. This will ensure that the original EUC programs are protected from unauthorized changes and that thecopies are run in a controlled environment. A secure library is a repository of EUC programs that have been tested, validated, and approved by the appropriate authority. Executing copies of EUC programs out of a secure library can also help with version control, backup, and recovery of EUC programs. Having an independent party review the source calculations, implementing complex password controls, and verifying EUC results through manual calculations are not as effective as executing copies of EUC programs out of a secure library, as they do not prevent or detect unintentional modifications of complex calculations in EUC. References: End-User Computing (EUC) Risks: A Comprehensive Guide, End User Computing (EUC) Risk Management

When verifying the accuracy and completeness of migrated data for a new application system replacing a legacy system, it is most effective for an IS auditor to review data analytics findings. Data analytics is a technique that uses software tools and statistical methods to analyze large volumes of data and identify patterns, anomalies, errors or inconsistencies. Data analytics can help to compare the source and target data sets, validate the data quality and integrity, and detect any data loss or corruption during the migration process. The other options are not as effective, because audit trails only record the actions performed on the data, acceptance testingresults only verify the functionality of the new system, and rollback plans only provide contingency measures in case of migration failure. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.6

 The greatest risk of using a reciprocal site for disaster recovery is the inability to utilize the site when required. A reciprocal site is an agreement between two organizations to provide backup facilities for each other in case of a disaster. However, this arrangement may not be reliable or enforceable, especially if both organizations are affected by the same disaster or have conflicting priorities. Therefore,the IS auditor should recommend that management consider alternative options for disaster recovery, such as dedicated sites or cloud services12. References:

 The best way to help management understand the associated risk of missing backup cycles due to operator error and lack of exception management is to explain the impact to disaster recovery. Disaster recovery is the process of restoring normal operations and functions after a disruptive event, such as a natural disaster, a cyberattack, or a hardware failure. Backup cycles are essential for disaster recovery, because they ensure that the organization has copies of its critical data and systems that can be restored in case of data loss or corruption. If backup cycles are missed due to operator error, and these exceptions are not managed, the organization may not have the latest or complete backups available for disaster recovery, which can result in prolonged downtime, reduced productivity, lost revenue, reputational damage, and legal or regulatory penalties. The other options are not as effective asexplaining the impact to disaster recovery, because they either do not address the risk of data loss or corruption, or they focus on operational or technical aspects rather than business outcomes. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.1
