B)A technique that ensures that the data transmitted using WiFi have not been altered
C)A way of providing mutual authentication between a user and an AS
D)None of the above

Answer 2

B

Question 3

Which of the following is not a central element of a typical antivirus scheme

A)detection
B)identification
C)removal
D)deterrence

Answer 3

D

Question 4

A security intrusion is defined as a successful attempt by a user to gain access to a system or system resource without proper authorization.

Question 5

The firewall cannot protect against attacks that the firewall

Question 6

IEEE 802.11i consists of two main functions: authentication and access control.

Question 7

The higher-layer protocols defined as part of SSL include:

A)handshake protocol
B)change cipher spec protocol
C)alert protocol
D)all of the above

Question 8

SSL performs encryption first,followed by computing a message authentication code.

Question 9

8,Generic decryption (GD)technology enables the antivirus program to easily detect even the most complex polymorphic viruses while maintaining fast scanning speeds.

Question 10

A key logical component of an IDS is:

A)sensors
B)analyzers
C)user interface
D)all of the above

Question 11

IPSec provides authentication,encryption,and key exchange functions.

Question 12

IPSec transport mode provides protection primarily for:

A)the Internet layer
B)upper-layer protocols
C)network and link-layer protocols
D)all of the above

Question 13

Typically,a firewall is inserted between the premises network and the Internet to establish a controlled link and to erect an outer security wall or perimeter.

Question 14

Ipsec is based primarily upon the DES standard.

Question 15

Transport mode in IPSec provides protection to the entire IP packet.

Question 16

A stateful inspection firewall

A)applies a set of rules to each incoming and outgoing IP packet and then forwards or discards the packet
B)controls TCP traffic by creating a directory of outbound TCP connections
C)acts as a relay of application-level traffic
D)sets up two TCP connections,one between itself and a TCP user on an inner host and one between itself and a TCP user on an outside host

Question 17

For VPNs,both authentication and are generally desired.

Question 18

IEEE 802.11i makes use of another standard that was designed to provide access control functions for LANs.The standard is .
