The best way to ensure data is properly sanitized while in cloud storage is to cryptographically scramble the data. Cryptographic scrambling is the process of transforming data into an unreadable form using a secret key or algorithm. Cryptographic scrambling protects the data from unauthorized access, modification, or deletion, even if the cloud storage provider or a third party gains access to the data. Cryptographic scrambling also ensures that the data can be restored to its original form using the same key or algorithm, if needed. The other options are not as effective as cryptographic scrambling, because they either do not completely remove the data,or they make it impossible to recover the data. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.3.1, page 3-21.

Key risk indicators (KRIs) are metrics that provide an early warning of increasing risk exposure in various areas of the organization. They help to monitor changes in the level of risk and enable timely actions to mitigate the risk. The most useful information for developing KRIs is the possible causes of materialized risk, which are the factors or events that trigger or contribute to the occurrence of a risk. By identifying the possible causes of materialized risk, an organization can design KRIs that measure the likelihood and impact of the risk, and alert the management when the risk exceeds the acceptable level. References = CRISC Review Manual, 7th Edition, page 101.

The most significant risk to an organization when updating the incident response plan is the undefined assignment of responsibility. An incident response plan is a document that defines the roles, responsibilities, procedures, and resources for responding to an incident that could disrupt the normal operations of the organization, or compromise its assets, reputation, or compliance. An incident response plan should clearly assign the responsibility for each task and activity involved in the incident response process, such as detection, containment, analysis, eradication, recovery, and reporting. Undefined assignment of responsibility could lead to confusion, duplication, conflict, or omission among the stakeholders, and impair the effectiveness and efficiency of the incident response process. Undefined assignment of responsibility could also increase the risk of escalation, recurrence, or impact of the incident, and affect the accountability and performance of the organization. Obsolete response documentation, increased stakeholder turnover, and failure to audit third-party providers are also risks, but they are not as significant as undefined assignment of responsibility, as they do not directly affect the execution and outcome of the incident response process. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 130.

 Internal Audit Review:

An internal audit review of control design involves a thorough examination of the control’s structure, implementation, and effectiveness.

Auditors use a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes.

 Steps in Audit Review:

Understand Control Objectives:Auditors ensure that the control is designed to meet specific risk management objectives.

Evaluate Implementation:Check whether the control has been implemented as designed.

Test Effectiveness:Perform tests to verify that the control operates effectively and consistently over time.

 Importance of Audit Review:

Provides independent and objective assurance that the control is appropriately designed and functioning as intended.

Identifies any deficiencies or areas for improvement in the control design.

 Comparing Other Validation Methods:

Senior Management Approval:Indicates support but does not validate effectiveness.

Documentation of Control Objectives:Important for understanding intent but not validation.

Control Owner Attestation:Provides insight but lacks the independence of an audit.
