It assigns values to assets.
It is exploratory.*
It is descriptive.*

It uses a mathematical model.

4. Why would an organization perform a quantitative risk analysis for network security threats?

so that management can determine the number of network devices needed to inspect, analyze, and protect the corporate resources
so that management has documentation about the number of security attacks that have occurred within a particular time period
so that the organization can focus resources where they are most needed*
so that the organization knows the top areas where network security holes exist

5. What is the purpose of the Tripwire network testing tool?

to perform vulnerability scanning
to assess configuration against established policies, recommended best practices, and compliance standards*
to detect unauthorized wired network access
to provide password auditing and recovery
to provide information about vulnerabilities and aid in penetration testing and IDS signature development

6. A network manager has presented to upper management that the threat of fire in the data center has an exposure factor of 70 percent. What does this mean?

70 percent of the data center area has a high risk of fire.
There is a 70 percent chance of a fire in the data center.
70 percent of all data center equipment would be destroyed if there were a fire.*

10. What is the main purpose of the Cisco SIO?

to guarantee every connection coming on or off the endpoint
to provide a method of introducing scanning elements into the network

11. Fill in the blank. risk analysis is used to estimate the probability and severity of threats to a system.

12. How does network scanning help assess operations security?

It can simulate attacks from malicious sources.
It can log abnormal activity.
It can detect open TCP ports on network systems.*
It can detect weak or blank passwords.

13. In quantitative risk analysis, what term is used to represent the degree of destruction that would occur if an event took place?

single loss expectancy
exposure factor*
annualized loss expectancy
annualized rate of occurrence

14. What security task is relevant in the disposition phase of the SDLC?

defining the levels of potential impact on an organization from a security breach
identifying the protection requirements for systems through a formal risk assessment process
ensuring that security plans are designed, developed, and implemented
ensuring that data is deleted, erased, or overwritten*

15. What should be the primary objective of a contingency and disaster recovery plan?

eliminate risk by avoiding threats to the network altogether
identify acceptable methods of recovery on events most likely to happen*
address every possible disaster scenario and assumption
implement protection mechanisms in an attempt to reduce risks to acceptable levels

16. Using quantitative risk analysis, what is the annualized loss expectancy to an organization of an event that has single loss expectancy of $500,000 and a annualized rate of occurrence of .03?


17. What component of the Cisco SecureX architecture automatically deploys security rules to Cisco devices?

policy management console
delivery mechanism
scanning engine

18. Which security policy component defines what users are allowed and not allowed to do on company systems?

authentication policy
governing policy
acceptable use policy*
application policy

19. A new network manager at a small company is presented with a list from the technician who is responsible for server backups. The technician provides the following list of current practices.

Blank media is always used.
Server backups are performed on a weekly basis.
Only three people (the technician, a peer, and the supervisor of the technician) have rights to perform the backups.
The technician stores the backups in a fire-proof safe in the wiring closet.
Twice a month, the technician and supervisor take a separate backup copy to a secure off-site location.

Which practice would it be best to modify in order to improve this process so it is in accordance with recommended best practices for a secure backup program?

More people should have rights to perform the backups.
Only one person is needed to store the off-site copy.
Two people should securely store the on-site backup media.*
Media can be rotated.
Backups should be done on a more frequent basis.

20. A new person has joined the security operations team for a manufacturing plant. What is a common scope of responsibility for this person?

physical and logical security of all business personnel
managing redundancy operations for all systems
day-to-day maintenance of network security*
data security on host devices

21. What is the objective of the governing policy in the security policy hierarchy structure?
