PICT848 APPLIED CYBER SECURITY1
Introduction
Computer and other related systems have become an important part of business and
commerce. With the passage of time, they become major point of target for attackers1. If an
individual wants to make use of system with confidence, then they need to assure the fact that the
devices are not comprised in anyhow. All the required communication with the devices needs to
be secured anyhow2.
In the essay, an idea has been provided with respect to fundamental concepts of
information system security along with various measures for mitigating the threats. An analysis
has been done with respect to method how the organization can easily stay secure. Various
measures have been discussed by which organization can improve the security has been
discussed.
Discussion
Information Security Triad
Confidentiality
At the instance of protecting information, user needs to restrict or stop the access to the
individual who is required view it. Everyone who is disallowed from learning needs to have an
idea with respect to complete content3. It is the complete essence of confidentiality like federal
laws needed to restricting the access to university.

Integrity
Integrity is all about assurance of the given information which is being accessed, is not
altered anyhow and aims to highlight the required thing. Information integrity is all about
making use of information which highlights the intended meaning. Information can easily lose its
integrity by the help of malicious content like a person who is not authorized to make change
intentionally4.
Availability
Proper availability of information is considered to be a part of CIA triad. The availability
point mainly tends to highlight the fact the given information can be easily accessed and
modified by any authorized person5. Based on the kind of information proper timeframe can
result in different kind of meanings. Both data and information system are made are available as
per the need6.
