Question 16

encryption key

Answer 16

A block of characters, used in combination with an encryption algo- rithm, to encrypt or decrypt a stream or block of data.

Question 17

enhanced interior gateway routing protocol (EIGRP)

Answer 17

A TCP/IP routing protocol that is used to transmit network routing information from one network router to an- other in order to determine the most efficient path through a large network.

Question 18

enterprise architecture

Answer 18

Activities that ensure important business needs are met by IT systems; the model that is used to map business functions into the IT environment and IT systems in increasing levels of detail.

Question 19

erasable programmable read-only memory (EPROM)

Answer 19

A form of permanent memo- ry that can be erased by shining ultraviolet (UV) light through a quartz window on the top of the chip.

Question 20

error handling

Answer 20

Functions that are performed when errors in processing are encountered.

Question 21

espionage

Answer 21

The act of spying on an organization.

Question 22

Ethernet

Answer 22

A standard protocol for assembling a stream of data into frames for trans- port over a physical medium from one station to another on a local area network. On an Ethernet network, any station is free to transmit a packet at any time, provided that another station is not already doing so.

Question 26

exposure factor (EF)

Answer 26

The financial loss that results from the realization of a threat, expressed as a percentage of the asset’s total value.
