Answers to Assessment Test
1. A. A privilege audit is used to determine that all groups, users, and other accounts have
the appropriate privileges assigned according to the policies of an organization. For more
information, see Chapter 8.
2. D. A mantrap limits access to a small number of individuals. It could be, for example, a
small room. Mantraps typically use electronic locks and other methods to control access.
For more information, see Chapter 6.
3. B. Public-Key Cryptography Standards is a set of voluntary standards for public-key cryp-
tography. This set of standards is coordinated by RSA. For more information, see Chapter 7.
4. B. Wired Equivalent Privacy (WEP) is designed to provide security equivalent to that of a
wired network. WEP has vulnerabilities and isn’t considered highly secure. For additional
information, see Chapter 7.
5. C. The Process layer interfaces with applications and encapsulates trafic through the
Host-to-Host or Transport layer, the Internet layer, and the Network Access layer. For
more information, see Chapter 2.
6. B. L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol that can be used between
LANs. L2TP isn’t secure, and you should use IPSec with it to provide data security. For
more information, see Chapter 3.
7. A. A DMZ (demilitarized zone) is an area in a network that allows restrictive access to
untrusted users and isolates the internal network from access by external users and systems.
It does so by using routers and irewalls to limit access to sensitive network resources. For
more information, see Chapter 1.
8. C. A key recovery process must be able to recover a previous key. If the previous key can’t
be recovered, then all the information for which the key was used will be irrecoverably lost.
For more information, see Chapter 7.
9. D. A lood attack is designed to overload a protocol or service by repeatedly initiating a
request for service. This type of attack usually results in a DoS (denial of service) situation
occurring because the protocol freezes or excessive bandwidth is used in the network as a
result of the requests. For more information, see Chapter 2.
10. B. A sensor collects data from the data source and passes it on to the analyzer. If the analyzer
determines that unusual activity has occurred, an alert may be generated. For additional infor-
mation, see Chapter 4.
11. A. Hardening is the term used to describe the process of securing a system. This is accom-
plished in many ways, including disabling unneeded protocols. For additional information on
hardening, see Chapter 5.
12. A. To meet the goal of integrity, you must verify that information being used is accurate
and hasn’t been tampered with. Integrity is coupled with accountability to ensure that data
is accurate and that a inal authority exists to verify this, if needed. For more information,
see Chapter 1.
13. D. Online Certiicate Status Protocol (OCSP) is the mechanism used to immediately verify
whether a certiicate is valid. The Certiicate Revocation List (CRL) is published on a regular
basis, but it isn’t current once it’s published. For additional information, see Chapter 7.
14. B. Partitioning is the process of breaking a network into smaller components that can each
be individually protected. The concept is the same as building walls in an ofice building. For
additional information, see Chapter 6.
15. A. IM and other systems allow unsuspecting users to download iles that may contain
viruses. Due to a weakness in the ile extension naming conventions, a ile that appears to
have one extension may actually have another extension. For example, the ile account.
doc.vbs would appear in many applications as account.doc, but it’s actually a Visual
Basic script and could contain malicious code. For additional information, see Chapter 4.
16. B. Access control lists (ACLs) are used to allow or deny an IP address access to a network.
ACL mechanisms are implemented in many routers, irewalls, and other network devices.
For additional information, see Chapter 5.
17. B. The default port for a web server is port 80. By changing the port to 1019, you force
users to specify this port when they are using a browser. This action provides a little addi-
tional security for your website. Adding a irewall to block port 80 would secure your web-
site so much that no one would be able to access it. For more information, see Chapter 3.
18. D. A worm is designed to multiply and propagate. Worms may carry viruses that cause sys-
tem destruction, but that isn’t their primary mission. For more information, see Chapter 2.
19. A. Social engineering is using human intelligence methods to gain access or information
about your organization. For additional information, see Chapter 6.
20. C. In most environments, FTP sends account and password information unencrypted.
This makes these accounts vulnerable to network snifing. For additional information, see
Chapter 5.
21. A. An intrusion detection system (IDS) provides active monitoring and rule-based responses
to unusual activities on a network. A irewall provides passive security by preventing access
from unauthorized trafic. If the irewall were compromised, the IDS would notify you based
on rules it’s designed to implement. For more information, see Chapter 3.
22. B. The chain of custody ensures that each step taken with evidence is documented and
accounted for from the point of collection. Chain of custody is the Who, What, When,
Where, and Why of evidence storage. For additional information, see Chapter 8.
23. A. Steganography is the process of hiding one message in another. Steganography may
also be referred to as electronic watermarking. For additional information, see Chapter 7.
24. C. The use policy is also referred to as the usage policy. It should state acceptable uses
of computer and organizational resources by employees. This policy should outline con-
sequences of noncompliance. For additional information, see Chapter 8.
25. B. The Key Exchange Algorithm (KEA) is used to create a temporary session to exchange
key information. This session creates a secret key. When the key has been exchanged, the
regular session begins. For more information, see Chapter 7.
26. A. Elliptic Curve Cryptography (ECC) would probably be your best choice for a PDA.
ECC is designed to work with smaller processors. The other systems may be options, but
they require more computing power than ECC. For additional information, see Chapter 7.
27. B. An incremental backup will generally be the fastest of the backup methods because
it backs up only the iles that have changed since the last incremental or full backup. See
Chapter 8 for more information.
28. C. Biometrics is the authentication process that uses physical characteristics, such as a palm
print or retinal pattern, to establish identiication. For more information, see Chapter 1.
29. C. Role-Based Access Control (RBAC) is primarily concerned with providing access to
systems that a user needs based on the user’s role in the organization. For more informa-
tion, see Chapter 8.
30. A. Computer forensics is the process of investigating a computer system to determine the
cause of an incident. Part of this process would be gathering evidence. For additional infor-
mation, see Chapter 8.
