surprised to find out that he is registering as a different member. What type of biometric
factor error occurred? - answerSince he was accepted as a different member this was a
Type 2 (false positive) error. If he was not accepted and the door remained locked it
would have been a Type 1 (false negative) error.

objects when labels match? - answerMandatory Access Control (MAC)
Mandatory Access Control is based on what type of model? - answerLattice Based
You need to create a trust relationship between your company and a vendor. You need
to implement the system so that it will allow users from the vendor's organization to
access your accounts payable system using the accounts created for them by the
vendor. What type of authentication do you need to implement? - answerThis type of
authentication, where one domain trusts users from another domain, is called
federation.
,Users change job positions quite often at your new company. Which type of access
control would make it easier to allow administrators to adjust permissions when these
changes occur?
A. Role-Based Access Control
B. Mandatory Access Control
C. Discretionary Access Control
D. Rule-Based Access Control - answerA Role-Based Access Control would assign
permission to roles and then the administrator would simply adjust the role of the user
when he or she changes jobs
Which of the following authenticators is appropriate to use by itself rather than in
combination with other biometric factors?
A. Voice pattern recognition
B. Hand geometry
C. Palm scans
D. Heart/pulse patterns - answerC. Palm scans compare the vein patterns in the palm to
a database to authenticate a user.
As part of hiring a new employee, Sven's identity management team creates a new user
object and ensures that the user object is available in the directories and systems where
it is needed. What is this process called? - answerProvisioning includes the creation,
maintenance, and removal of user objects from applications, systems, and directories.
The Linux filesystem allows the owners of objects to determine the access rights that
subjects have to them. What type of access control does Linux use? -
answerDiscretionary Access Control
Mary's organization handles very sensitive governmental agency information. They
need to implement an access control system that allows administrators to set access
rights but does not allow the delegation of those rights to other users. What is the best
type of access control design for Mary's organization? - answerMandatory Access
Control (MAC) systems allow an administrator to configure access permissions but do
not allow users to delegate permission to others.
What term is used to describe the default set of privileges assigned to a user when a
new account is created?
A. Aggregation
B. Transitivity
C. Baseline
D. Entitlement - answerD. Entitlement refers to the privileges granted to useres when an
account is first provisioned.
Steve is the risk manager for a company on the east coast of the United States. He
recently undertook a replacement cost analysis and determined that rebuilding and
reconfiguring the data center would cost $20 million. Steve consulted with hurricane
experts, data center specialists, and structural engineers and they determined that a
, typical CAT 3 hurricane that successfully hits the east coast would cause approximately
$5 million in damages. The meteorologists determined that Steve's facility lies in an
area where they are likely to experience a CAT 3 hurricane once every 10 years.
Based upon the information in this scenario, what is the exposure factor for the effect of
a CAT 3 hurricane on Steve's data center? - answerThe exposure factor is the
percentage of the facility that risk managers expect will be damaged if a risk
materializes. It is calculated by dividing the amount of damage by the asset value. In
this case, that is $5 million in damage divided by the $20 million facility value, or 25
percent.

What is the annualized loss expectancy for a hurricane at Steve's data center? -
answerThe annualized loss expectancy (ALE) is calculated by multiplying the single
loss expectancy (SLE) by the annualized rate of occurrence (ARO). In this case the SLE
is $5 million and the ARO is .10. Multiplying those numbers together gives you the ALE
of $500,00.
Earlier this year, the information security team at Jeff's company identified a
vulnerability in a server that he is responsible for. He immediately applied the patch and
is sure that it installed properly, but after running the vulnerability scanner has continued
to incorrectly flag the system as vulnerable because of the version number it is finding
even though Jeff is sure the patch is installed. Which of the following options is Jim's
best choice to deal with the issue?
A. Uninstall and reinstall the patch
B. Ask the information security team to flag the system as patched and not vulnerable.
C. Update the version information in the web server's configuration.
D. Review the vulnerability report and use alternate remediation options. - answerB. Jeff
should ask the information security team to flag the issue as resolved if he is sure the
patch was installed. Many vulnerability scanners rely on version information or banner
information may flag patched versions if the software provider does not update the
information they see.
