Mark is attempting to evaluate the potential impact of a firewall breach at his company.
He is only looking at the relationship between the threats, vulnerabilities, and controls to
evaluate the impact of a hypothetical breach. What type of approach to risk analysis is
this? -CORRECTANSWER Qualitative
Mark is using the qualitative approach which uses descriptions and words to measure
the likelihood and impact of a risk. Examining the relationships between threats,
vulnerabilities, and controls without quantitative measurements is a qualitative
approach. Because some aspects of security can be difficult to measure, the qualitative
approach is commonly used.
If SLE of a risk is $25,000 and ARO occurs once every four years, then what will be the
ALE? -CORRECTANSWER $6,250
The ALE (annual loss expectancy) value is calculated by multiplying an SLE by its ARO
to determine the financial magnitude of a risk on an annual basis.
,ALE (annual loss expectancy) = SLE (single loss expectancy) X ARO (annual rate of
occurrence)
If SLE of a risk is $25,000 and ARO occurs once every four years, then ALE is $6,250
($25,000*0.25).

incidents than other parts of the company. Which of the following management controls
she can use to improve the security of the branch office? -CORRECTANSWER
Continuous monitoring processes
Rena should perform continuous monitoring processes to improve the security of the
branch office. Continuous monitoring involves regular measurements of network traffic
levels, routine evaluations for regulatory compliance, and checks of network security
device configurations. It defines exactly what events and environments should be
monitored based on a prior risk analysis. It also points toward the never-ending review
of what resources a user actually accesses, which is critical for preventing insider
threats.
A company is hiring a penetration tester and wants to exclude social engineering from
the list of authorized activities. Which of the following documents should include these
details? -CORRECTANSWER SLA
, SLA (Service-level Agreement) document includes all of these details. SLA defines what

Services may include everything from hardware and software to human resources. A
strong SLA will outline basic service expectations for liability purposes. The document
may include timeframes within which failures will be repaired or serviced; guarantees of
uptime; or, in the case of a network provider, guarantees of data upload and download
rates.
