Your company has a single, centralized web-based retail sales system.
Orders come in 12 hours per day, 364 days per year. Sales average
$500,000 per day. Attacks against the retail sales system occur on a
daily basis.
For the retail sales system, there is a 1% chance of a hacker bringing the
system down. The mean time to restore the system is 6 hours. What is
the ALE for this system?
A. $912,500
B. $250,000
C. $500,000
D. $910,000
Answer: D
Explanation: The annualized loss expectancy (ALE) for the system is
$910,000. The asset value (AV) is $500,000. The exposure factor (EF) is 0.5
(6 hours/12 hours).
Single loss expectancy (SLE) = AV × EF = $500,000 × 0.5 = $250,000
Annualized rate of occurrence (ARO) = 0.01 × 364 = 3.64
, Annualized loss expectancy (ALE) = SLE × ARO = $250,000 × 3.64 =
$910,000
