A typical risk assessment matrix uses a 5×5 grid, with likelihood and impact categories (e.g., Very Low, Low, Medium, High, Very High) on each axis. The matrix categorizes risks based on their likelihood of occurrence and their potential impact. For example:

Risk Assessment Matrix Example

Likelihood (Horizontal Axis): Very Low, Low, Medium, High, Very High

Impact (Vertical Axis): Very Low, Low, Medium, High, Very High

Each cell in the matrix represents a risk level. Risks falling into the higher-risk categories (e.g., High Impact, High Likelihood) require immediate attention and mitigation efforts. Risks in lower-risk categories may require less immediate action, but should still be monitored.

Risk Prioritization:

• High-Risk: Risks with a high likelihood and high impact require immediate attention and mitigation. Examples include data breaches or significant service outages.
• Medium-Risk: Risks with a medium likelihood or impact require careful monitoring and proactive mitigation planning. Examples include application compatibility issues or moderate performance degradation.
• Low-Risk: Risks with a low likelihood and low impact can be monitored and addressed as needed. Examples include minor configuration errors or limited data loss.

Matrix Application:

For each identified risk, the organization should:

1. Assess the likelihood of the risk occurring.
2. Assess the potential impact if the risk occurs.
3. Plot the risk on the matrix based on its likelihood and impact.
4. Develop and implement mitigation strategies for high-priority risks.
5. Monitor the effectiveness of the mitigation strategies and adjust as needed.
