The Annualized Loss Expectancy (ALE) is a measure that is used to calculate the expected financial loss that an organization may face due to a specific security threat over a one-year period. The formula used to calculate ALE is ALE = AV * EF * ARO, where AV is the Asset Value, EF is the Exposure Factor, and ARO is the Annualized Rate of Occurrence.

The Asset Value (AV) represents the monetary value of an asset to an organization. It is the total cost of the asset, including the purchase price, recurring maintenance expenses, and any other costs that may be associated with it. In other words, it is the estimated value of the asset to the organization, and it is used to determine the potential financial impact that a security breach or incident may have on the organization.

The Exposure Factor (EF) represents the percentage of loss that an asset may experience if a security breach or incident occurs. It takes into account the extent of damage that may be caused by the breach or incident, such as the amount of data that may be lost or the amount of downtime that may be experienced.

The Annualized Rate of Occurrence (ARO) represents the number of times that a specific security threat may occur within a one-year period. It takes into account the probability or likelihood of the threat occurring, based on historical data or other factors.

By multiplying these three values together, the ALE provides an estimate of the potential financial impact that a security threat may have on the organization over a one-year period. This information can be used by the organization to determine the cost-benefit of implementing specific security measures or to prioritize which threats to address first.
