Final answer:
The Single Loss Expectancy (SLE) is the potential financial loss from a security incident. It is calculated by multiplying the asset value by the exposure factor. For a facility suffering from a fire, the SLE represents the estimated financial loss from the fire.
Step-by-step explanation:
The Single Loss Expectancy (SLE) is a term used in the field of risk management and information security. It refers to the potential financial loss that can occur from a single security incident or event. In the context of a facility suffering from a fire, the SLE would represent the estimated financial loss that would result from the fire.
Calculating the SLE involves multiplying the Asset Value (AV) by the Exposure Factor (EF). The AV represents the value of the asset at risk, in this case the facility. The EF represents the percentage of loss that would occur if the fire were to happen.
For example, if the AV of the facility is $1,000,000 and the EF for a fire is estimated to be 50%, then the SLE would be $500,000. This means that if a fire were to occur, the facility could potentially suffer a financial loss of $500,000.
