And to do this, we use a specific formula to calculate the annual loss expectancy, or the ALE.
speaker_0HOST
So the ALE is the amount of money we are mathematically expected to lose to this specific problem every single year.
speaker_1HOST
Correct.
speaker_1HOST
And the formula is beautifully simple, at least on paper.
speaker_1HOST
ALE equals the cost of the incident multiplied by the occurrences per year.

Scenario A, we have a fragile legacy database.
Sec GuyHOST
If we lose 10 laptops a year, your ARO is 10.
Sec GuyHOST
Multiply them together and you get the ALE, or annual loss expectancy.
Sec GuyHOST
In this case, $10,000.
Sec GuyHOST
This number is your most powerful tool.
Sec GuyHOST
You accept the risk.
Sec GuyHOST
To fully manage the board's expectations, we have to talk about the four pillars of risk treatment.
