The __________ attack is the easiest to defend against because the opponent has the least
amount of information to work with.
Security attacks are classified as either passive or aggressive. True or False
False
Authentication protocols and encryption algorithms are examples of security
mechanisms. True or False
True
Symmetric encryption is used to conceal the contents of blocks or streams of data of any
size, including messages, files, encryption keys, and passwords.
True
The data integrity service inserts bits into gaps in a data stream to frustrate traffic
analysis attempts.
False
Data origin authentication does not provide protection against the modification of data
units.
True
__________ is the most common method used to conceal small blocks of data, such as
encryption keys and hash function values, which are used in digital signatures.
Symmetric Encryption
,Data Integrity Algorithm
Authentication Protocols
Asymmetric Encryption
Asymmetric Encryption
A common technique for masking contents of messages or other information traffic so
that opponents can not extract the information from the message is __________
integrity
analysis

Verifying that users are who they say they are and that each input arriving at the
system came from a trusted source is _________
authenticity
An __________ attack attempts to alter system resources or affect their operation
rude
passive
eavesdropping
active
active

integrity
An attack tree is a branching, hierarchical data structure that represents a set of
potential techniques for exploiting security vulnerabilities. True or False
True
In the context of network security, access control is the ability to limit and control the
access to host systems and applications via communications links. True or False
True
Encryption prevents either sender or receiver from denying a transmitted message.
Thus, when a message is sent, the receiver can prove that the alleged sender in fact sent
the message and when a message is received, the sender can prove that the alleged
receiver in fact received the message.
