What can be defined as secret communications where the very existence of the message is hidden?
Steganography is a secret communication where the very existence of the message is hidden. For example, in a digital image, the least significant bit of each word can be used to comprise a message without causing any significant change in the image. Key clustering is a situation in which a plaintext message generates identical ciphertext messages using the same transformation algorithm but with different keys. Cryptology encompasses cryptography and cryptanalysis. The Vernam Cipher, also called a one-time pad, is an encryption scheme using a random key of the same size as the message and is used only once. It is said to be unbreakable, even with infinite resources.

Which of the following best defines add-on security?
The Internet Security Glossary (RFC2828) defines add-on security as 'The retrofitting of protection mechanisms, implemented by hardware or software, after the [automatic data processing] system has become operational.'
Source: SHIREY, Robert W., RFC2828: Internet Security Glossary, may 2000.
Which of the following protects a password from eavesdroppers and supports the encryption of communication?
CHAP: A protocol that uses a three way hanbdshake The server sends the client a challenge which includes a random value(a nonce) to thwart replay attacks. The client responds with the MD5 hash of the nonce and the password.
The authentication is successful if the client's response is the one that the server expected.
CHAP protects the password from eavesdroppers and supports the encryption of communication.
What can a packet filtering firewall also be called?
While neither CBK nor AIO3 use the term 'screening router,' they both discuss how the packet filtering capabilities of a router can be used to block traffic much like a packet filtering firewall. Krutz and Vine use this term on p. 90.
'A scanning router' is incorrect. This is a nonsense term to distract you.
'A shielding router' is incorrect. This is a nonsense term to distract you.
'A sniffing router' is incorrect. This is a nonsense term to distract you.

AIO3, pp.484 - 485
The security of a computer application is most effective and economical in which of the following cases?
The earlier in the process that security is planned for and implement the cheaper it is. It is also much more efficient if security is addressed in each phase of the development cycle rather than an add-on because it gets more complicated to add at the end. If security plan is developed at the beginning it ensures that security won't be overlooked.
The following answers are incorrect:
The system is optimized prior to the addition of security. Is incorrect because if you wait to implement security after a system is completed the cost of adding security increases dramtically and can become much more complex.
The system is procured off-the-shelf. Is incorrect because it is often difficult to add security to off-the shelf systems.
The system is customized to meet the specific security threat. Is incorrect because this is a distractor. This implies only a single threat.
