Create a chart with four columns. Label the columns Asset, Threats, Probabilities, and Security Controls. List all assets in a standard room of your house. Then write down threats that could damage or destroy each asset. Example-leaky roof, exposed wires. Next examine the probability of that threat occurring. Example-if leaky roof is the threat and you live in a area with frequent rainfall, the probability of that threat occurring and causing damage is high. Next, determine security controls to reduce the threats. Beginning with the first asset, look for ways to manage the risks.
