1. True or False? Crypto techniques originally focused on confidentiality. -
ANSWER ✓ True
2. Which of the following security protections is used to prevent passive attacks?
- ANSWER ✓ Confidentiality
3. We use cryptography to apply all of the following protections to network
traffic, except: - ANSWER ✓ reliability
4. True or False? Eavesdropping without interfering with communications would
be considered a passive attack. - ANSWER ✓ True
,5. True or False? A network attack in which someone forges network traffic
would be considered an active attack. - ANSWER ✓ True
6. When we place crypto in different protocol layers, we often balance two
important properties: - ANSWER ✓ application transparency and network
transparency.
7. Wireless Protected Access, version 2 (WPA2.) falls under: - ANSWER ✓
802.11.
8. We are trying to protect our traffic as much as possible from sniffing. To
minimize the risk, should we encrypt as much of our packets as possible,
including headers? - ANSWER ✓ Yes, because plaintext headers open our
network messages to traffic analysis.
9. In typical applications, does SSL provide application transparency? -
ANSWER ✓ No, because the SSL software is traditionally integrated into the
application software package and is not supported unless the application
specifically provides it.
10. Virtual private networking is used primarily for encrypting: - ANSWER ✓ a
connection between two sites across the internet.
,11. Secure Sockets Layer (SSL) has been replaced by: - ANSWER ✓ Transport
Layer Security (TLS).
12. The principal application of IPsec is: - ANSWER ✓ virtual private networking.
13. Which of the following network protocols typically provide application
transparency? Select all that apply. - ANSWER ✓ a) Wi-Fi Protected Access
14. b) IPsec
15. True or False? Encryption works against traffic filtering, because the filtering
process can't detect malicious content in encrypted packets. - ANSWER ✓
True
16. True or False? We clearly need to use encryption if we wish to protect against
sniffing. - ANSWER ✓ True
17. __________ rely on traffic analysis when the defenders use encryption that
is too difficult to attack. - ANSWER ✓ Attackers
18. Producing one encryption key for each cryptonet or communicating pair and
distributing that key to the appropriate endpoints is called: - ANSWER ✓
manual keying.
, 19. True or False? When replacing crypto keys, they must be all replaced 1 month
at a time. - ANSWER ✓ False
20. True or False? In manual keying, two encryption keys are produced for
each cryptonet or communicating pair and those keys are distributed to the
appropriate endpoints. - ANSWER ✓ False
21. True or False? Self-rekeying transforms an existing encryption key into a new
one using a pseudorandom number generator. - ANSWER ✓ True
22. The process of transforming an existing key into a new one is called: -
ANSWER ✓ self-rekeying.
23.Associate the following concepts with the appropriate secret-key building
blocks. - ANSWER ✓ Key wrapping
24. Build a unique TEK from nonces and a secret - ANSWER ✓ Shared secret
hashing
25. Shares a separate KEK with each registered user - ANSWER ✓ Key
distribution center
