Information and Network Security

Concepts

Cybersecurity (1 of 3)

Cybersecurity 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 cyberspace

environment and organization and users’ assets.

Organization and users’ assets include connected computing

devices, personnel, infrastructure, applications, services,

telecommunications systems, and the totality of transmitted

and/or stored information in the cyberspace environment.

Cybersecurity (2 of 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. The general security objectives

comprise the following: availability; integrity, which may

include data authenticity and nonrepudiation; and

confidentiality

Cybersecurity (3 of 3)

Information Security

• This term refers to preservation of confidentiality, integrity,

and availability of information. In addition, other properties,

such as authenticity, accountability, nonrepudiation, and

reliability can also be involved

Network Security

• This term refers to protection of networks and their service

from unauthorized modification, destruction, or disclosure,

and provision of assurance that the network performs its

critical functions correctly and there are no harmful side

effects

Security Objectives (1 of 2)

• The cybersecurity definition introduces three key

objectives that are at the heart of information and network

security:

– Confidentiality: This term covers two related

concepts:

▪ Data confidentiality: Assures that private or

confidential information is not made available or

disclosed to unauthorized individuals

▪ Privacy: Assures that individuals control or

influence what information related to them may be

collected and stored and by whom and to whom

that information may be disclosed

Security Objectives (2 of 2)

• Integrity: This term covers two related concepts:

– Data integrity: Assures that data and programs are changed only

in a specified and authorized manner. This concept also

encompasses data authenticity, which means that a digital object

is indeed what it claims to be or what it is claimed to be, and

nonrepudiation, which is assurance that the sender of information

is provided with proof
