The IS auditor’s most important course of action after finding that several similar incidents were logged during the audit period is to determine if a root cause analysis was conducted. A root cause analysis is a systematic process that identifies the underlying causes of system failures or incidents. A root cause analysis can help to prevent recurrence of similar incidents, improve system performance and reliability, and enhance incident management processes. The IS auditor should evaluate whether a root cause analysis was performed for each incident, whether it was timely and thorough, and whether it resulted in effective corrective actions.

The best source of information for assessing the effectiveness of IT process monitoring is performance data. Performance data is a type of information that measures and reports on the results or outcomes of IT processes, such as availability, reliability, throughput, response time, or error rate. Performance data can help assess the effectiveness of IT process monitoring by providing quantitative and qualitative indicators of whether IT processes are meeting their objectives, standards, or expectations. The other options are not as good as performance data in assessing the effectiveness of IT process monitoring, as they do not provide direct or objective evidence of IT process results or outcomes. Real-time audit software is a type of tool that can help automate and facilitate audit activities, such as data collection, analysis, or reporting, but it does not provide information on IT process performance. Quality assurance (QA) reviews are a type of activity that can help evaluate and improve the quality of IT processes, products, or services, but they do not provide information on IT process performance. Participative management techniques are a type of method that can help involve and motivate IT staff in decision-making and problem-solving processes, but they do not provide information on IT process performance. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

Referential integrity is a property of data that ensures that all references between tables are valid and consistent. Disabling referential integrity controls can result in orphaned records, data anomalies, and inaccurate queries. The most effective way to compensate for the lack of referential integrity is to perform periodic table link checks, which verify that all foreign keys match existing primary keys in the related tables. More frequent data backups, concurrent access controls, and performance monitoring tools do not address the issue of data consistency and accuracy. References: ISACACISA Review Manual 27th Edition, page 291

The best recommendation for a small IT web development company where developers must have write access to production is to remove production access from the developers. Production access is the ability to modify or update the live systems or applications that are used by customers or end users. Production access should be restricted to authorized and qualified personnel only, as any changes or errors in production can affect the functionality, performance, or security of the systems or applications. Developers should not have write access to production, as they may introduce bugs,vulnerabilities, or inconsistencies in the code that can compromise the quality or reliability of the systems or applications. The other options are not as effective as removing production access from the developers, as they do not address the root cause of the problem or provide the same benefits. Hiring another person to perform migration to production is a costly solution that can help segregate the roles and responsibilities of developers and migrators, but it does not remove production access from the developers. Implementing continuous monitoring controls is a good practice that can help detect and correct any issues or anomalies in production, but it does not remove production access from the developers. Performing a user access review for the development team is a detective control that can help verify and validate the access rights and privileges of developers, but it does not remove production access from the developers. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2
