In this article, what do we know about the 3 principles of information security 3 principles? Also, we will discuss the importance of these 3 principles in information security.

The Information Security 3 Principles

What are the 3 principles of information security? Before discussing information security 3 principles.

We need to understand some basic terminologies of information security which are as below:

Information Security Principles

Security Principles

An information security principle is a practice or procedure. That has been established to enhance the security of an organization’s information. 

So the procedures are created by the organization to help secure its information resources.

Information Security 3 Principles

Now let us discuss these 3 principles. So the principles of information security are the following:

  • Confidentiality
  • Integrity 
  • Availability

These principles are also known as CIA. These principles are the most essential in information security. 

So the CIA is used in many areas of computing including the following:

  • cryptography
  • computer architecture
  • operating systems
  • networking
  • data storage
  • application software
  • hardware development

It is necessary to protect the confidentiality, integrity, and availability of an organization’s assets. If any one of these assets is compromised.

Then it would hurt the business operations of the organization.

Details Of Principles Of Information Security

Now to know more details about the 3 principles of information security. Let us discuss each of the principles from the following:


Confidentiality is the principle of protecting the information from unauthorized access. An organization needs to prevent unauthorized access to the information.

If an unauthorized person has access to the information. Then it would harm the operations of the organization. 

The main objective of confidentiality is to protect an organization’s assets from being disclosed. So that the organization can maintain a competitive advantage over its competitors.

Confidentiality is a very important principle in information security. It is used in the following ways:

  • Data encryption
  • Physical security
  • Non-disclosure agreements
  • Data classification
  • Access control systems etc.


Integrity is also known as authenticity, correctness, and non-repudiation. Also, integrity ensures that data has not been altered or corrupted in an unauthorized manner. 

It ensures that data has been altered or corrupted by a person. Also, a process should not be treated as reliable and trusted by any other entity or process. 

So Integrity ensures that data has not been altered without authorization. Integrity protection should be provided at all levels of storage devices including computers.

Also, the mobile devices, networks, and cloud storage systems. To improve integrity protection, organizations use many tools such as:

Data validation techniques such as hashing algorithms. Also, checksum functions for detection of data corruption during transmission and storage, etc.


Availability is the principle of ensuring that systems. Also, information is available when needed by authorized people.


It is also known as the availability of systems, applications, and information. Availability ensures that systems are available at all times without any downtime. 

So downtime of the system would harm the business operations of an organization. Also, an organization needs to ensure that the data is available at all times. 

If data is not available at the required time. Then it would harm the business operations of the organization. 

Also, it would make it impossible for the employees to access data on time. So it would create problems in the operational efficiency of an organization. 

An organization can improve availability by using many techniques such as the following: 

  • availability facilities of cloud computing
  • redundancy
  • fault-tolerance etc.
