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.
