How residual risk can be determined?

A. B. C. D.D.
All risks are determined by risk assessment, regardless whether risks are residual or not.
Incorrect Answers: A: Determining remaining vulnerabilities after countermeasures are in place says nothing about threats, therefore risk cannot be determined.
B: Transferring all the risks in not relevant to determining residual risk.
It is one of the method of risk management.
C: Risk cannot be determined by threat analysis alone, regardless whether it is residual or not.
Residual risk is the level of risk that remains after the implementation of security controls or countermeasures. It is an essential aspect of risk management as it helps organizations to identify the level of risk that they are still exposed to and evaluate the effectiveness of the implemented controls.
To determine the residual risk, an organization needs to follow a process that involves the following steps:
Conduct a risk assessment: This step involves identifying and assessing the risks that the organization is exposed to. The risk assessment should be comprehensive and cover all areas of the organization, including people, processes, and technology.
Implement security controls: Once the risks have been identified and assessed, the organization should implement appropriate security controls to mitigate the risks. These controls could include technical, administrative, or physical controls.
Determine the effectiveness of the controls: The organization needs to evaluate the effectiveness of the implemented controls to determine if they have reduced the level of risk to an acceptable level.
Assess the residual risk: After the controls have been implemented, the residual risk needs to be assessed. This involves identifying the remaining risks that the organization is still exposed to. The residual risk can be calculated by subtracting the level of risk that has been mitigated by the controls from the initial risk level.
Review and monitor: Finally, the organization needs to regularly review and monitor the residual risk to ensure that the controls are effective and that the level of risk is acceptable.
Therefore, option A is the correct answer as determining the remaining vulnerabilities after countermeasures are in place is a critical step in assessing the residual risk.
