Explanation
The information security manager should compare the level of residual risk with the organization's risk appetite to inform a risk treatment decision. Residual risk is the risk that remains after applying the risk treatment options, such as avoiding, transferring, mitigating, or accepting the risk. Risk appetite is the amount of risk that the organization is willing to accept to achieve its objectives. The information security manager should ensure that the residual risk is within the risk appetite, and if not, apply additional risk treatment measures or escalate the risk to the senior management for approval.
