Residual Risk Assessment Next Step

B.

After completing a risk assessment and determining residual risk, the next step for an information security manager depends on the context and objectives of the organization. However, based on the available options, the recommended step would be to conduct an evaluation of controls (option A).

The evaluation of controls is important to ensure that the existing controls are effective in mitigating the identified risks. The information security manager should review the control measures already in place and determine if they are adequate to address the residual risk or if additional controls are required.

Once the evaluation is complete, the information security manager can then proceed to implement countermeasures to mitigate risk (option C) if required. This step involves selecting and implementing the appropriate security controls to reduce the residual risk to an acceptable level.

Before implementing countermeasures, it is important to determine if the risk is within the organization's risk appetite (option B). If the residual risk is within the organization's risk appetite, the organization may decide to accept the risk without implementing additional controls. However, if the risk is outside the risk appetite, the organization should consider implementing additional controls or transferring the risk.

Classifying all identified risks (option D) is an important step in the risk management process, but it is not the immediate next step after determining the residual risk. Risk classification involves categorizing risks based on their potential impact and likelihood, which helps in prioritizing risk mitigation efforts. However, this step should be done at the beginning of the risk management process, not after determining residual risk.
