📖 What is Risk Treatment?
Risk treatment is the process of selecting and implementing measures to modify risk to an acceptable level. This process involves analyzing the cost-benefit of various strategies, such as mitigation, transfer, avoidance, or acceptance, to reduce risk to within the defined appetite.
"On the exam, always look for the most cost-effective treatment option that brings the risk within the organization's appetite without exceeding the asset's value."

🔑 What are the Key Concepts of Risk Treatment?
- ▸ Risk Mitigation involves implementing security controls to reduce the likelihood or impact of a threat, bringing the risk down to an acceptable level.
- ▸ Risk Transfer shifts the financial impact of a potential loss to a third party, typically through insurance policies or outsourcing specific business functions.
- ▸ Risk Avoidance eliminates the risk entirely by deciding not to engage in the activity or removing the asset that creates the vulnerability.
- ▸ Risk Acceptance occurs when the organization acknowledges the risk and takes no action, often because the cost of treatment exceeds the potential loss.
- ▸ Residual Risk is the remaining level of risk after treatment measures have been applied; it must be reviewed against the organization's risk appetite.
🎯 How does Risk Treatment appear on the CISM Exam?
You may be asked to recommend the best risk treatment strategy for a low-impact risk where the cost of implementing a control is higher than the potential loss. In this case, risk acceptance is typically the correct answer.
A scenario might describe a business process that is too risky to manage despite available controls. You will need to identify 'Risk Avoidance' as the appropriate strategy to eliminate the threat entirely.
Expect questions where you must evaluate multiple treatment options and select the one that provides the most cost-effective reduction of risk to within the organization's appetite without exceeding the asset's value.
❓ Frequently Asked Questions
What is the difference between risk mitigation and risk avoidance?
Mitigation reduces the risk to an acceptable level while allowing the business activity to continue. Avoidance completely stops the activity or removes the asset to eliminate the risk entirely.
When should a CISM recommend risk acceptance over mitigation?
Acceptance is recommended when the risk falls within the predefined risk appetite or when the cost of the control outweighs the benefit of the risk reduction, making mitigation financially unjustifiable.
