INFORMATION SYSTEMS SECURITY C845
SSCP - COMPOSITE MASSIVE TEST
QUESTIONS WITH CORRECT ANSWERS
Which of the following is not a type of attack used against access controls?
Teardrop - Dictionary, brute-force, and man-in-the-middle attacks are all types of
attacks that are frequently aimed at access controls. Teardrop attacks are a type of
denial-of-service attack.
George is assisting a prosecutor with a case against a hacker who attempted to
break into the computer systems at George's company. He provides system logs
to the prosecutor for use as evidence, but the prosecutor insists that George
testify in court about how he gathered the logs. What rule of evidence requires
George's testimony?
Hearsay rule - The hearsay rule says that a witness cannot testify about what someone
else told them, except under specific exceptions. The courts have applied the hearsay
rule to include the concept that attorneys may not introduce logs into evidence unless
they are authenticated by the system administrator. The best evidence rule states that
copies of documents may not be submitted into evidence if the originals are available.
The parol evidence rule states that if two parties enter into a written agreement, that
written document is assumed to contain all the terms of the agreement. Testimonial
evidence is a type of evidence, not a rule of evidence.
Jim has been asked to individually identify devices that users are bringing to
work as part of a new BYOD policy. The devices will not be joined to a central
,MEDSTUDY.COM
management system like Active Directory, but he still needs to uniquely identify
the systems. Which of the following options will provide Jim with the best means
of reliably identifying each unique device?
Use device fingerprinting via a web-based registration system - Device fingerprinting via
a web portal can require user authentication and can gather data like operating
systems, versions, software information, and many other factors that can uniquely
identify systems. Using an automated fingerprinting system is preferable to handling
manual registration, and pairing user authentication with data gathering provides more
detail than a port scan. MAC addresses can be spoofed, and systems may have more
than one depending on how many network interfaces they have, which can make
unique identification challenging.
Greg would like to implement application control technology in his organization.
He would like to limit users to installing only approved software on their systems.
What type of application control would be appropriate in this situation?
Bluelisting - The whitelisting approach to application control allows users to install only
those software packages specifically approved by administrators. This would be an
appropriate approach in a scenario where application installation needs to be tightly
controlled.
Which pair of the following factors is key for user acceptance of biometric
identification systems?
The throughput rate and the time required to enroll - Biometric systems can face major
usability challenges if the time to enroll is long (more than a couple of minutes) and if
the speed at which the biometric system is able to scan and accept or reject the user is
,MEDSTUDY.COM
too slow. FAR and FRR may be important in the design decisions made by
administrators or designers, but they aren't typically visible to users. CER and ERR are
the same and are the point where FAR and FRR meet. Reference profile requirements
are a system requirement, not a user requirement.
Sally is wiring a gigabit Ethernet network. What cabling choices should she make
to ensure she can use her network at the full 1000 Mbps she wants to provide to
her users?
Category 5e and Category 6 UTP cable are both rated to 1000 Mbps. Cat 5 (not Cat 5e)
is rated only to 100 Mbps, whereas Cat 7 is rated to 10 Gbps. There is no Cat 4e.
If Alex hires a new employee and the employee's account is provisioned after HR
manually inputs information into the provisioning system based on data Alex
provides via a series of forms, what type of provisioning has occurred?
Workflow-based account provisioning - Provisioning that occurs through an established
workflow, such as through an HR process, is workflow-based account provisioning. If
Alex had set up accounts for his new hire on the systems he manages, he would have
been using discretionary account provisioning. If the provisioning system allowed the
new hire to sign up for an account on their own, they would have used self-service
account provisioning, and if there was a central, software-driven process, rather than
HR forms, it would have been automated account provisioning.
Alex has access to B, C, and D. What concern should he raise to the university's
identity management team?
B - Application Servers
, MEDSTUDY.COM
C - Database Servers
D - Active Directory
F - Incident Management System
E - Directory Server
Privilege creep may be taking place. - As Alex has changed roles, he retained access to
systems that he no longer administers. The provisioning system has provided rights to
workstations and the application servers he manages, but he should not have access to
the databases he no longer administers. Privilege levels are not specified, so we can't
determine whether he has excessive rights. Logging may or may not be enabled, but it
isn't possible to tell from the problem.
When Alex changes roles, what should occur?
He should be provisioned for only the rights that match his role. - When a user's role
changes, they should be provisioned based on their role and other access entitlements.
Deprovisioning and reprovisioning is time-consuming and can lead to problems with
changed IDs and how existing credentials work. Simply adding new rights leads to
privilege creep, and matching another user's rights can lead to excessive privileges
because of privilege creep for that other user.
Vivian works for a chain of retail stores and would like to use a software product
that restricts the software used on point-of-sale terminals to those packages on a
preapproved list. What approach should Vivian use?
Whitelist - The blacklist approach to application control blocks certain prohibited
packages but allows the installation of other software on systems. The whitelist
approach uses the reverse philosophy and allows only approved software. Antivirus
