In order to secure additional budget, a security manager wants to quantify the financial impact of a one-time
compromise. Which of the following is MOST important to the security manager?

A.
Impact

B.
SLE

C.
ALE

D.
ARO

Explanation:
SLE is a monetary value, and it represents how much you expect to lose at any one time: the single loss
expectancy. SLE can be divided into two components: AV (asset value) and the EF (exposure factor). Thus, a
one-time compromise would resort under the SLE for the security manager.
