Introduction
The CIA triad consists of three different aspects of the cybersecurity needs.
Confidentiality is the protection of important information from falling into the
wrong hands, integrity involves you constantly protecting the data over time, and
the availability of information should always be there for the people who are
supposed to have access to it.

Why is it important?
The CIA Triad is important because it has a easy to understand framework for an
organization trying to upgrade their security. They can use the three aspects
together to develop a simple and balanced security method to gain trust with your
partners.

Authentication & Authorization
Authentication and authorization could be viewed as similar but they have their
differences in the types of security they are. Authentication means verifying the
identity of an individual through methods like logging in or two-factor
authentication while authorization is the system that grants or denies access to
information based on the identity that the individual is using. For example, say
you’re typing a document for work and you needed feedback from your peers. You
have to determine who is authorized to view that certain document and the people
who were sent the document have to authenticate themselves to log into the
software the document is on.
