CHAPTER 1: COMPUTER AND NETWORK SECURITY CONCEPTS


TRUE OR FALSE


T F 1. The OSI security architecture focuses on security attacks,
mechanisms, and services.
LU
T F 2. Security attacks are classified as either passive or aggressive.

T F 3. Cybersecurity strives to ensure the attainment and maintenance of
the security properties of the organization and users’ assets against
relevant security risks in the cyberspace environment.
XE
T F 4. Information security and network security are subsets of
cybersecurity.

T F 5. Data authenticity assures that private or confidential information is
not made available or disclosed to unauthorized individuals.
LI
T F 6. The OSI security architecture focuses on security attacks,
mechanisms, and services.

T F 7. An active attack attempts to alter system resources or affect their
BR
operation.

T F 8. Authentication exchange is the use of a trusted third party to
assure certain properties of a data exchange.

T F 9. A loss of integrity is the unauthorized modification or destruction
AR
of information.

T F 10. The emphasis in dealing with active attacks is on prevention
rather than detection.

T F 11. The connection-oriented integrity service addresses both
Y
message stream modification and denial of service.

T F 12. The denial of service prevents or inhibits the normal use or
management of communication facilities.

T F 13. Integrity can apply to a stream of messages, a single message, or

selected fields within a message.


T F 14. Passive attacks are very easy to detect because they involve
alteration of the data.

T F 15. Security services implement security policies and are
implemented by security mechanisms.
LU
MULTIPLE CHOICE


1. is the collection of tools, policies, security concepts, security
safeguards, guidelines, risk management approaches, actions, training, best
practices, assurance, and technologies that can be used to protect the
XE
cyberspace environment and organization and users’ assets.

A) Access control B) Data authenticity

C) Cybersecurity D) Authentication
LI
2. A common technique for masking contents of messages or other information
traffic so that opponents can not extract the information from the message is
BR
.

A) integrity B) encryption

C) analysis D) masquerade
AR
3. involves the passive capture of a data unit and its subsequent
retransmission to produce an unauthorized effect.

A) Disruption B) Replay
Y
C) Service denial D) Masquerade


4. is a branch of mathematics that deals with the transformation of data.

A) Cryptography B) Modularity
