When reviewing a data classification scheme, it is most important for an IS auditor to determine if the security criteria are clearly documented for each classification. This will help the IS auditor to evaluate if the data classification scheme is consistent, comprehensive, and aligned with the organizational objectives and regulatory requirements. The security criteria should define the level of confidentiality,integrity, and availability for each data classification, aswell as the corresponding controls such as access control, rights management, and cryptographic protection1. The other options are less important or incorrect because:

A. Each information asset is not necessarily assigned to a different classification. Data classification schemesusually have a limited number of categories, such as “Sensitive,” “Confidential,” and “Public,” and multiple information assets can belong to the same category2.

C. Senior IT managers are not necessarily identified as information owners. Information owners are typically the business units or functions that create, use, or maintain the information assets, and they may or may not be senior IT managers3.

D. The information owner is not required to approve access to the asset. The information owner is responsible for defining the access requirements and rules for the asset, but the actual approval of access requests may be delegated to other roles, such as data custodians or administrators3. References: Simplify and Contextualize Your Data Classification Efforts - ISACA, 3.7: Establish and Maintain a Data Classification Scheme, Data Classification and Practices - NIST, CISA Exam Content Outline |CISA Certification | ISACA

 A corrective control is a control that aims to restore normal operations after a disruption or incident has occurred. Executing emergency response plans is an example of a corrective control, as it helps to mitigate the impact of an incident and resume business functions. Separating equipment development testing and production is a preventive control, as it helps to avoid errors or unauthorized changes in production systems. Verifying duplicate calculations in data processing is a detective control, as it helps to identify errors or anomalies in data processing. Reviewing user access rights for segregation is also a detective control, as it helps to detect any violations of segregation of duties principles. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 64

 The most important thing for an IS auditor to confirm when reviewing an organization’s plans to implement robotic process automation (RPA) to automate routine business tasks is that the end-to-end process is understood and documented. This is because RPA involves the use of software robots or digital workers to mimic human actions and execute predefined rules and workflows. Therefore, it is essential that the IS auditor verifies that the organization has a clear and accurate understanding of the current state of the process, the desired state of the process, the inputs and outputs, the exceptions and errors, the roles and responsibilities, and the performance measures12. Without a properdocumentation of the end-to-end process, the organizationmay face challenges in designing, developing, testing, deploying, and monitoring the RPA solution3. References: 1: CISA ReviewManual (Digital Version), Chapter 4: Information Systems Operations and Business Resilience, Section 4.2: IT Service Delivery and Support, page 211 2:CISA Online Review Course, Module 4: Information Systems Operations and Business Resilience, Lesson 4.2: IT Service Delivery and Support 3: ISACA Journal Volume 5, 2019, Article: Robotic Process Automation: Benefits, Risks and Controls

File transfer protocol (FTP) is a service that allows users to transfer files between computers over a network. If enabled within firewall rules, FTP would present the greatest risk, as it can expose sensitive data to unauthorized access, modification, or deletion. FTP does not provide encryption or authentication, which makes it vulnerable to eavesdropping, spoofing, and tampering attacks. Simple mail transfer protocol (SMTP), simple object access protocol (SOAP), and hypertext transfer protocol (HTTP) are also services that can be used to exchange data over a network, but they have more security features than FTP, such as encryption, authentication, or validation. References: CISA Review Manual (Digital Version)
