Residual system access is the risk that the customer service representatives who are transferred to the sales department may still have access to the systems or applications that they used in their previous role, which may not be relevant or authorized for their new role.

The access control manager is the person or function who is responsible for defining, implementing, and maintaining the policies and procedures for granting, modifying, reviewing, and revoking access rights to the systems or applications, based on the principle of least privilege and the segregation of duties.

The access control manager is responsible for mitigating the risk associated with residual system access, by ensuring that the access rights of the customer service representatives are updated or removed according to their new role and responsibilities, and that the access changes are documented and approved by the appropriate authorities.

The other options are not responsible for mitigating the risk associated with residual system access. They are either irrelevant or less effective than the access control manager.

 The first step when conducting a business impact analysis (BIA) is identifying critical information assets. A BIA is a process of analyzing the potential impacts of disruptive events on the business processes,functions, and resources. A BIA identifies the criticality, dependencies, recovery priorities, and recovery objectives of the business processes, and quantifies the financial and non-financial impacts of disruption. Information assets are the data, information, and knowledge that are essential for the operation and performance of the business processes. Identifying critical information assets is the first step of the BIA, as it helps to determine which information assets are vital for the continuity and recovery of the business processes, and whichinformation assets are most vulnerable or exposed to the disruptive events. Identifying critical information assets also helps to scope and focus the BIA on the most important and relevant information assets, and to avoid unnecessary or redundant analysis. Identifying events impacting continuity of operations, creating a data classification scheme, and analyzing previous risk assessment results are not the first steps of the BIA, as they are either the inputs or the outputs of the BIA, and they depend on the identification of critical information assets. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 130.

 A risk register is a document that records and tracks the identified risks, their causes, impacts, likelihood, responses, and status. A risk register can help manage and communicate risks throughout the risk management process. A risk register should be updated regularly to reflect the current state of risks and their responses. Due to a change in business processes, an identified risk scenario may no longer require mitigation, as the risk level may have decreased or the risk may have been eliminated. However, the risk should remain in the risk register, as the most important reason is to monitor for potential changes to the risk scenario. This means keeping track of the internal and external factors that may affect the risk scenario, such as new threats, vulnerabilities, opportunities, or controls. Monitoring for potential changes to the risk scenario can help identify and respond to any emerging or reoccurring risks, and ensure that therisk register is accurate and complete. References = Risk and Information Systems Control Study Manual, Chapter 1: IT Risk Identification, Section 1.3: Risk Register, p. 41-43.
