Question 1

E

Answer 1

The 3DES encryption algorithm.

Question 2

Eavesdropping

Answer 2

A type of attack involving the reading of messages that are not intended for the subject.

Question 3

Eavesdropping

Answer 3

An attack similar to sniffing, but includes recording or listening to conversations.

Question 4

ECB

Answer 4

Electronic Codebook is a DES mode that takes each 64-bit block and encrypts it with a key.

Question 5

ECPA

Answer 5

The Electronic Communications Privacy Act of 1986 was the first entry into privacy issues concerning electronic communication. The law made it a crime to invade a persons electronic privacy such as e-mail, voice mail, and cell phone monitoring.

Question 6

El Gamal

Answer 6

An asymmetrical cryptographic algorithm that uses large integers and modular arithmetic to calculate keys.

Question 7

Encapsulation

Answer 7

A feature gained through object-oriented programming that allows data to be hidden and stored as a unit in an object. The data may only be accessed through predefined methods.

Question 8

Encryption

Answer 8

The process of rendering data incomprehensible to unauthorized users by applying an algorithm to alter the datas appearance.

Question 9

Enigma Machine

Answer 9

A machine developed by the Germans during World War II. The machine was made up of rotors that rotated depending on the key set, therefore encrypting a message. This machine was never broken, only duplicated.

Question 10

EPROM

Answer 10

Erasable programmable read-only memory is where the BIOS is burned into the chip. It is memory that can be erased using UV light through a small window embedded into the top of the chip.

Question 11

Espionage

Answer 11

An act where the goal is to steal something of value from someone else. Espionage can sometimes be copying something that is very valuable.

Question 12

Ethernet

Answer 12

A common LAN architecture using a bus or star topology and the CSMA/CD access method to manage simultaneous communication demands. Ethernet is the basis for the IEEE 802.3 standard.

Question 13

Evidence

Answer 13

Any hardware, software, or data that can be used to verify the origin and details of an incident.

Question 14

Execution Cycle

Answer 14

A three-step cycle that includes fetching instructions from memory, decoding the instructions, and executing the instructions.

Question 15

Expert System

Answer 15

A knowledge-based system that stores a large volume of data in one area of specialty, simulating the knowledge and decisions of an expert human.

Question 16

FAR

Answer 16

False Acceptance Rate is the rate at which a biometrics system accepts an invalid subject.

Question 17

Fault Tolerance

Answer 17

A computer system or component designed so that in the case of a failure of either hardware or software, another backup system immediately takes its place with no loss of service.

Question 18

FDDI

Answer 18

Fiber Distributed Data Interface is a standard used by LANs wired with fiber-optic cable for data transmission.

Question 19

Fence

Answer 19

A physical access control that defines a perimeter barrier, marking the inside from the outside.

Question 20

Field

Answer 20

A section of a database record that contains a single piece of information.

Question 21

File Infector

Answer 21

A virus that modifies or replaces an executable file. A file infector activates when the infected file is run.

Question 22

Financial Attack

Answer 22

A type of attack that attempts to improperly acquire goods, services, or money in order to benefit the attacker.

Question 23

Firewall

Answer 23

A method used to protect a network system against intrusions from unauthorized users or systems. A firewall will block unsecured connections based on protocol or untrustworthy relationships.

Question 24

Firewall

Answer 24

A method used to protect a network system from intrusions from unauthorized users or systems. A firewall will block unsecured connections based on protocol or untrustworthy relationships.

Question 25

Firmware

Answer 25

Software that is stored on a ROM chip.

Question 26

Flooding

Answer 26

A type of DoS attack that sends a large number of packets to a victims machine without responding to the victims acknowledgements, making the victim maintain the maximum number of open connections and allowing no new connections to be made.

Question 27

Frame Relay

Answer 27

A switched data-link layer protocol that uses a form of HDLC encapsulation to handle multiple virtual circuits.

Question 28

FRR

Answer 28

False Rejection Rate is the rate at which a biometrics system would reject a valid subject.

Question 29

Full-interruption Test

Answer 29

The only real test that is not a simulation. The primary data centers power is cut and the data is then recovered at the alternative site. The test must be preauthorized as it can cause a substantial business process interruption.

Question 30

Full Backup

Answer 30

A backup type which dumps all important data files out to a different device such as tape, disk, archive file, or system-to-system over the network.

Question 31

Fun Attack

Answer 31

A type of attack that is executed for the thrill and prestige of the attacker.
