Answer 21

A combination of hardware and software that acts as a gatekeeper and prevents unauthorized users from accessing private networks.

Question 22

Answer 22

feature full-time monitoring tools placed at the most vulnerable points, or “hot spots”, of corporate networks to protect against suspicious network traffic and attempts to access files and databases

Question 23

What is antivirus software?

Answer 23

software designed to detect, and often eliminate, malware from an information system.

Question 24

What is encryption?

Answer 24

The process of encoding messages before they enter the network or airwaves, and then decoding at the receiving end

Question 25

What is symmetric key encryption?

Answer 25

• Also known as secret key encryption
• Both the sender and receiver use the same digital key to encrypt and decrypt message
• Requires a different set of keys for each entity with whom communication takes place
• Assumes the medium over which the key is shared is secure

Question 26

What is public key encryption?

Answer 26

• Solves symmetric key encryption problem of having to exchange secret key
• Uses two mathematically related digital keys – public key (widely disseminated) and private key (kept secret by owner)
• Once key used to encrypt message, same key cannot be used to decrypt message
• For example, sender uses recipient’s public key to encrypt message; recipient uses his/her private key to decrypt it

Question 27

What are two methods for encrypting network traffic on the web?

Answer 27

• Secure Sockets Layer (SSL) and successor Transport Layer Security (TLS)
• Secure Hypertext Transfer Protocol (S-HTTP)

Question 28

What is Secure Sockets Layer (SSL) and successor Transport Layer Security (TLS)?

Answer 28

Works by using public key encryption to create a secure connection between a client and a server thereby enabling any amount of data to be sent securely.

Question 29

What is Secure Hypertext Transfer Protocol (S-HTTP)?

Answer 29

Allows messages to be encapsulated in various ways, which may include encryption or the use of digital certificates. Differs from SSL in that it is designed only to transmit individual messages securely.
