Data processing is the activity of collecting, organizing, transforming, and analyzing data to produce useful information for decision making or other purposes12.

The role of the internal IT team in this situation is data processors, which are the people or entities that process data on behalf of the data controllers, who are the people or entities that determine the purposes and means of the data processing34.

Data processors are the role of the internal IT team because they are responsible for managing information through the applications that are used by the organization, and they act under the instructions and authority of the organization, which is the data controller34.

Data processors are also the role of the internal IT team because they have to comply with the data protection laws and regulations that apply to the data processing, and they have to ensure the security and confidentiality of the data34.

The other options are not the role of the internal IT team, but rather possible roles or terms that are related to data processing. For example:

Data custodians are the people or entities that have physical or logical control over the data, and they are responsible for implementing and maintaining the technical and administrative safeguards to protect the data56. However, this role is not the role of the internal IT team because it is a subset or function of the data processor role, and it does not reflect the full scope of the data processing activities that the internal IT team performs56.

Data owners are the people or entities that have legal rights or authority over the data, and they are responsible for defining and enforcing the policies and rules for the data access, use, and quality . However, this role is not the role of the internal IT team because it is a different or separate role from the data processor role, and it does not reflect the relationship or agreement between the organization and the internal IT team . References =

 Check totals are IT controls that verify the accuracy and completeness of data by comparing the sum or count of data records or data fields with a predetermined or expected value. Check totals can help detect and prevent errors, omissions, or alterations in data entry, processing, or transmission. Check totals can also help identify and correct data discrepancies or anomalies. Therefore, check totals are the most useful IT controls in mitigating the risk associated with inaccurate data. The other options are not the best answers because they do not directly address the risk of inaccurate data. Encrypted storage of data is an IT control that protects the confidentiality and integrity of data by preventing unauthorized access or modification. However, encryption does not ensure the accuracy or validity of the data itself. Links to source data are IT controls that provide traceability and transparency of data by allowing users to access or view the original data from which the derived or aggregated data is obtained. However, links to source data do not verify or correct the data quality or consistency. Audit trails for updates and deletions are IT controls that record the history and changes of data by capturing the date, time, user, and action performed on the data. Audit trails can help monitor and review the data activities and transactions, but they do not prevent or detect the data errors or inaccuracies. References = CRISC Review Manual, pages 164-1651; CRISC Review Questions, Answers & Explanations Manual, page 722

Nonrepudiation is the ability to prevent or deny the parties involved in an electronic transaction from disputing or rejecting the validity or authenticity of the transaction. Nonrepudiation ensures that the parties cannot claim that they did not send or receive the transaction, or that the transaction was altered or tampered with.

The tool that helps ensure compliance with a nonrepudiation policy requirement for electronic transactions is digital signatures, which are the electronic equivalents of handwritten signatures that are used to verify the identity and integrity of the sender and the content of the transaction. Digital signatures are generated by applying a cryptographic algorithm to the transaction, using the sender’s private key, which is a secret and unique code that only the sender knows and possesses. The digital signature can be verified by the receiver or any third party, using the sender’s public key, which is a code that is publicly available and corresponds to the sender’s private key. The digital signature can prove that the transaction was sent by the sender, and that the transaction was not altered or tampered with during the transmission.

The other options are not the tools that help ensure compliance with a nonrepudiation policy requirement for electronic transactions, because they do not provide the same level of verification and validation that digital signatures provide, and they may not be sufficient or effective to prevent or deny the parties from disputing or rejecting the transaction.

Encrypted passwords are the passwords that are converted into a secret or unreadable form, using a cryptographic algorithm, to protect them from unauthorized access or disclosure. Encrypted passwords can help to ensure the confidentiality and security of the passwords, but they are not the tools that help ensure compliance with a nonrepudiation policy requirement for electronic transactions, because they do not verify the identity and integrity of the sender and the content of the transaction, and they may not prevent or deny the parties from disputing or rejecting the transaction.

One-time passwords are the passwords that are valid or usable for only one session or transaction, and that are randomly generated or derived from a dynamic factor, such as time, location, or device. One-time passwords can help to enhance the security and authentication of the parties involved in the transaction, but they are not the tools that help ensure compliance with a nonrepudiation policy requirement for electronic transactions, because they do not verify the identity and integrity of the sender and the content of the transaction, and they may not prevent or deny the parties from disputing or rejecting the transaction.

Digital certificates are the electronic documents that contain the information and credentials of the parties involved in the transaction, such as their name, public key, expiration date, etc., and that are issued and signed by a trusted authority or entity, such as a certificate authority or a digital signature provider. Digital certificates can help to establish and confirm the identity and trustworthiness of the parties involved in the transaction, but they are not the tools that help ensure compliance with a nonrepudiation policy requirement for electronic transactions, because they do not verify the identity and integrity of the sender and the content of the transaction, and they may not prevent or deny the parties from disputing or rejecting the transaction. References =

CRISC Practice Quiz and Exam Prep

An IT risk register is a document that records and tracks the IT-related risks that an organization faces, as well as the information and actions related to those risks, such as the risk description, assessment, response, status, and owner. An IT risk register is a valuable tool for managing and communicating IT risks and their impact on the organization’s objectives and operations. However, an IT risk register may also contain sensitive or confidential information that should not be disclosed or shared with unauthorized or irrelevant parties, as it may compromise the security, privacy, or reputation of the organization or its stakeholders. Therefore, the risk manager’s best approach to the request from the head of a business operations department to review the entire IT risk register is to determine the purpose of the request before sharing the register. This is a technique to understand and evaluate the reason and the need for the request, as well as the scope and the level of access that the requester requires or expects. By determining the purpose of the request, the risk manager can ensure that the request is legitimate, appropriate, and relevant, and that the requester has a clear and valid interest or stake in the IT risk register. The risk manager can also ensure that the request is aligned with the organization’s policies, procedures, and standards for IT risk management and information sharing. The risk manager can also use the purpose of the request to decide what and how much information to share with the requester, and what conditions or restrictions to apply, such as confidentiality, accuracy, or timeliness. The other options are not the best approaches to the request from the head of a business operations department to review the entire IT risk register, as they may be premature, unnecessary, or ineffective. Escalating to senior management is a technique to involve or inform the higher-level authorities or decision makers about the request, which may be useful or required in some cases, but it may not be the first or the best step to take, as it may delay or complicate the process, or undermine the risk manager’s authority or responsibility. Requiring a nondisclosure agreement is a technique to protect the confidentiality and integrity of the information in the IT risk register by legally binding the requester to not disclose or misuse the information. However, a nondisclosure agreement may not be needed or appropriate in every case, and it may not prevent or address other issues or risks related to the information sharing, such as relevance, accuracy, or timeliness. Sanitizing portions of the register is a technique to remove or redact the sensitive or confidential information from the IT risk register before sharing it with the requester, which may be necessary or prudent in some cases, but it may not be sufficient or satisfactory, as it may affect the completeness, usefulness, or validity of the information, or raise questions or concerns from the requester.
