A risk register is a document that records and tracks the information about the risks that may affect the organization’s objectives, such as the risk description, category, source, cause, impact, probability, status, owner, response, etc.

When updating the risk register after a risk assessment, the most important information to include is the likelihood and impact of the risk scenario. This means that the risk registershouldreflect the current or updated estimates of the probability and consequence of the risk scenario, based on the risk analysis and evaluation methods and criteria.

The likelihood and impact of the risk scenario helps to determine the risk level and priority, select the most appropriate risk response, allocate the resources and budget for risk management, and monitor and report the risk performance and outcomes.

The other options are not the most important information to include when updating the risk register after a risk assessment. They are either secondary or not essential for risk management.

 The primary purpose of using key risk indicators (KRIs) to illustrate changes in the risk profile is to communicate risk trends to stakeholders. KRIs are metrics that provide an early warning of increasing risk exposure in various areas of the organization. By using KRIs to illustrate changes in the risk profile, the organization can communicate the risk trends to the stakeholders, such as the board, senior management, business units, and external parties, and enable them to take appropriate actions to manage the risk. Assigning ownership of emerging risk scenarios, highlighting noncompliance with the risk policy, and identifying threats to emerging technologies are other possible purposes, but they are not as important as communicating risk trends to stakeholders. References = ISACA Certified in Risk and Information Systems Control(CRISC) Certification Exam Question and Answers, question 12; CRISC Review Manual, 6th Edition, page 215.

Encryption is a technique that transforms data into an unreadable format using a secret key, so that only authorized parties can access and decrypt the data. Encryption can help to protectsensitive data from unauthorized access or disclosure, especially when the data is stored or transmitted in the cloud1.

Ensuring the vendor does not know the encryption key is a control that will best reduce the risk associated with a data breach, because it can help to:

Prevent the vendor from accessing or disclosing the sensitive data, intentionally or unintentionally

Limit the exposure or impact of the data breach, even if the vendor’s systems or networks are compromised by hackers or malicious insiders

Maintain the confidentiality and integrity of the sensitive data, regardless of the vendor’s liability or responsibility

Enhance the trust and confidence of the customers and stakeholders, who may be concerned about the vendor’s refusal to accept liability for a data breach23

The other options are not as effective as ensuring the vendor does not know the encryption key for reducing the risk associated with a data breach. Engaging a third party to validate operational controls is a control that can help to verify and improve the vendor’s security practices and processes, but it does not guarantee that the vendor will prevent or respond to a data breach adequately or timely. Using the same cloud vendor as a competitor is not a control, but rather a business decision that may increase the risk associated with a data breach, as the vendor may have access to or disclose the sensitive data of both parties, or may favor one party over the other. Using field-level encryption with a vendor supplied key is a control that can help to encrypt specific fields or columns of data, such as names, addresses, or credit card numbers, but it does not prevent the vendor from accessing or disclosing the data, as the vendor has the encryption key4. References =

Risk appetite is the best criterion to determine whether higher residual risk ratings in the risk register should be accepted, as it reflects the amount and type of risk that an organization is willing to take in pursuit of its objectives. Residual risk is the level of risk that remains after applying controls or other risk treatments. By comparing the residual risk ratings against the risk appetite, an organization can decide whether to accept, reduce, transfer, or avoid the risk. If the residual risk is within or below the risk appetite, the organization may accept the risk as tolerable. If the residual risk is above the risk appetite, the organization may not accept the risk as acceptable, and may seek further risk treatments or escalation.
