Isaca CISA Based on Real Exam Environment

This is the most effective way for the organization to improve its data classification processes and procedures, because data owners are the ones who are responsible for assigning the appropriate level of classification to the data they create, collect, or manage. Data owners should be aware of the data classification policy, the criteria for each level of classification, and the implications of misclassification. IT security staff can provide tailored training for data owners based on their roles, functions, and types of data they handle.

The other options are not as effective as having IT security staff conduct targeted training for data owners:

Use automatic document classification based on content. This is a possible option, but it may not be feasible or accurate for a small organization. Automatic document classification is a process that uses artificial intelligence or machine learning to analyze the content of a document and assign a class label based on predefined rules or models. However, this process may requirea lot of resources, expertise, and maintenance, and it may not capture all the nuances and context of the data. The IS auditor should also verify the reliability and validity of the automatic document classification system.

Publish the data classification policy on the corporate web portal. This is a good practice, but it is not enough to improve the data classification situation. Publishing the data classification policy on the corporate web portal can increase the visibility and accessibility of the policy, but it does not ensure that data owners will read, understand, and follow it. The IS auditor should also monitor and enforce the compliance with the policy.

Conduct awareness presentations and seminars for information classification policies. This is a useful measure, but it is not the most effective one. Conducting awareness presentations and seminars can raise the general awareness and knowledge of information classification policies among all employees, but it may not address the specific needs and challenges of data owners. The IS auditor should also provide more in-depth and practical training for data owners.

 Verification of hash totals is a detective control. A detective control is a control that aims to identify and report errors or irregularities that have already occurred. Verification of hash totals is a technique that compares the hash values of data before and after transmission or processing to detect any changes or corruption. The other options are examples of other types of controls, such as programmed edit checks (preventive), backup procedures (recovery), and use of pass cards (preventive). References: CISA Review Manual, 27th Edition, page 223

The IS auditor’s primary concern when an organization has recently implemented a Voice-over IP (VoIP) communication system is a single point of failure for both voice and data communications. VoIP is a technology that allows voice communication over IP networks such as the internet. VoIP can offer benefits such as lower costs, higher flexibility, and better integration with other applications. However, VoIP also introduces risks such as dependency on network availability, performance, and security. If both voice and data communications share the same network infrastructure and devices, then a single point of failure can affect both services simultaneously and cause significant disruption to business operations. Therefore, the IS auditor should evaluate the availability and redundancy of the network components and devices that support VoIP communication. The other options are not as critical as a single point of failure for both voice and data communications, as they do not pose a direct threat to business continuity. References: CISA Review Manual, 27th Edition, page 385
