Risk assessment heat maps, however, do shine in certain areas. They can be helpful tools in effective risk management when used in the right context. When risk heat maps are built on solid, objective risk analysis, they are a valuable tool.
Risk management heat maps cannot convey accurate threat data if an organization does not have a strong risk analysis model in place. Without the necessary groundwork, it is far too superficial to assign risk scores on a heat map arbitrarily. But what’s involved in laying this groundwork, exactly?
After determining the scope of your risk assessment, you will need to ask these questions to get started on a cybersecurity heat map process:
- What are the most critical systems and assets?
- For each asset, what are the potential consequences should it be compromised?
- What is my organization’s risk tolerance?
- What is my organization’s risk appetite?
- What existing security solutions do I have in place?
- Who is responsible for coordinating my risk management strategy?
After assessing your unique set of risks, you can calculate each risk using this formula:
Risk = Potential Impact × Probability of Occurrence
Once risks have been analyzed and calculated, you will be better prepared to plot the risks on a heat map to help your team hold discussions and prioritize the risks facing your business.
A typical risk management heat map uses a traffic-light color scale ranging from green to red and features likelihood (or frequency) and impact (or magnitude) on opposing axes. Green denotes mild risks, yellow denotes medium risk, and red denotes high risk. Your risk mitigation and minimization tactics can be influenced by this knowledge.
What Are the Benefits of a Risk Heat Map?
Communicate Risk and Improve Decision-making
Since the map is a powerful visual tool, it helps business leaders who have no prior training in risk management understand the severity of each risk and take action to address it. Looking at a risk map, the management can decide to mitigate the risk or capitalize on the opportunity created by the risk in alignment with its risk appetite.
Holistic View of Risk
Risk maps enable decision-makers to view the total risk environment at a high level, providing a birds-eye view of risk across the scope of your assessment.
