 The best way to proceed when an independent penetration test results show a high-rated vulnerability in a cloud-based application that is close to going live is to assess whether the vulnerability is within the organization’s risk tolerance levels. This is because the organization should not implement the application without understanding the potential impact and likelihood of the vulnerability being exploited, and the cost and benefit of fixing or mitigating the vulnerability. The organization should also consider the contractual and legal obligations, service level agreements, and performance expectations of the cloud service provider and the application users. By assessing the risk tolerance levels, the organization can make an informed and rational decision on whether to accept, transfer, avoid, or reduce the risk, and how to allocate the resources and responsibilities for managing the risk.

Implementing the application and requesting the cloud service provider to fix the vulnerability is not the best way to proceed, because it exposes the organization to unnecessary and unacceptable risk, and it may violate the terms and conditions of the cloud service contract. The organization should not rely on the cloud service provider to fix the vulnerability, as the provider may not have the same level of urgency, accountability, or capability as the organization. The organization should also not assume that the vulnerability will not be exploited, as cyberattackers may target the cloud-based application due to its high visibility, accessibility, and value.

Commissioning further penetration tests to validate initial test results is not the best way to proceed, because it may delay the implementation of the application, and it may not provide any additional or useful information. The organization should trust the results of the independent penetration test, as it is conducted by a qualified and objective third party. The organization should also not waste time and resources on conducting redundant or unnecessary tests, as it may affect the budget, schedule, and quality of the project.

Postponing the implementation until the vulnerability has been fixed is not the best way to proceed, because it may not be feasible or desirable for the organization. The organization should consider the business impact and opportunity cost of postponing the implementation, as it may affect the organization’s reputation, revenue, and customer satisfaction. The organization should also consider the technical feasibility and complexity of fixing the vulnerability, as it may require significant changes or modifications to the application or the cloud environment. The organization should not adopt a zero-risk or risk-averse approach, as it may hinder the organization’s innovation and competitiveness. References =

The incident response team can best leverage the results of a business impact analysis (BIA) by assigning restoration priority during incidents. A BIA is a process that identifies and evaluates the criticality and dependency of the organization’s business functions, processes, and resources, and the potential impacts and consequences of their disruption or loss. The BIA results provide the basis for determining the recovery objectives, strategies, and plans for the organization’s business continuity and disaster recovery. By using the BIA results, the incident response team can prioritize the restoration of the most critical and time-sensitive business functions, processes, and resources, and allocate the appropriate resources, personnel, and time to minimize the impact and duration of the incident.

Determining total cost of ownership (TCO) (B) is not a relevant way to leverage the results of a BIA, as it is not directly related to incident response. TCO is a financial metric that estimates the total direct and indirect costs of owning and operating an asset or a system over its lifecycle. TCO may be useful for evaluating the cost-effectiveness and return on investment of different security solutions or alternatives, but it does not help the incident response team to respond to or recover from an incident.

Evaluating vendors critical to business recovery © is also not a relevant way to leverage the results of a BIA, as it is not a primary responsibility of the incident response team. Evaluating vendors critical to business recovery is a part of the vendor management process, which involves selecting, contracting, monitoring, and reviewing the vendors that provide essential products or services to support the organization’s business continuity and disaster recovery. Evaluating vendors critical to business recovery may be done before or after an incident, but not during an incident, as it does not contribute to the incident response or restoration activities.

Calculating residual risk after the incident recovery phase (D) is also not a relevant way to leverage the results of a BIA, as it is not a timely or effective use of the BIA results. Residual risk is the risk that remains after the implementation of risk treatment or mitigation measures. Calculating residual risk after the incident recovery phase may be done as a part of the incident review or improvement process, but not during the incident response or restoration phase, as it does not help the incident response team to resolve or contain the incident.

= Change management controls are the most effective in preventing the introduction of vulnerabilities that may disrupt the availability of a critical business application. Change management controls are the policies, procedures, and practices that govern the initiation, approval, implementation, testing, and documentation of changes to the information systems and infrastructure. Change management controls help to ensure that changes are authorized, planned, controlled, and monitored, and that they do not introduce any unintended or adverse effects on the security, functionality, performance, or reliability of the system or application. Change management controls also help to identify and mitigate any potential risks or issues that may arise from the changes, and to ensure that the changes are aligned with the business objectives and requirements. By implementing change management controls, the organization can prevent the introduction of vulnerabilities that may disrupt the availability of a critical business application, as well as enhance the quality and efficiency of the change process. References = CISM Review Manual 15th Edition, page 105, page 106.
