Information Security Components

The Three Information Security Components

What are the following information security three components that we should know? Also, let us know its importance for our company data system.

Introduction About The Three Information Security Components

Three components of information security are confidentiality, integrity, and availability.

The three components of information security are:

  • Confidentiality
  • Integrity
  • Availability

We will know about these three components and their importance.


Confidentiality protects the privacy of data by ensuring that only the intended recipient can see it. If we do not protect the confidentiality of data, anyone who has access to the data will be able to see it.

Confidentiality is one of the three most important principles of information security.


Integrity ensures that data cannot be modified without being detected. If we do not ensure the integrity of data, then it can be modified without our knowledge.

So as a result, we may end up using corrupted data. Which can damage our systems and cause us to lose information.

For example, if we change a file without being aware that we are doing this. Then the data in the file will become corrupted.

When it happens, if someone modifies a file on our computer. Especially while we are working on it.

We might not be aware that the file is changed. It is because we would only be looking at the file that we are working on.

We would probably not even notice that the file is modified. In this case, the integrity of the data is compromised.


Availability ensures that data is accessible. Especially, in the time it needs to be viewed.

If we do not ensure the availability of data, then users may not be able to access it. As a result, they may lose valuable information.

For instance, if a user cannot access certain files then it can be a big problem. Such as a high possibility that he or she will compromise with other stakeholders.

So, ensuring that information is always available to users can help keep them happy. Also, secure and at ease that any moment they need it, it is there.

We should also note that these three principles are all equally important. They are like a chain – if one link in the chain breaks, then it will affect the entire chain.

Also, the three links will break eventually. So we have to ensure that all three links in this chain are kept strong.

It is to keep them all safe from damage. Far from any attacks.

More About Information Security

To improve information security, we need to know what information security is.

So what is Information Security? It is a process to protect data from any attacks. As well as unauthorized access to it.

However, it is not something that happens automatically. This means that we need to put in a lot of effort.

It is for us to make sure that data remains secure.

There are many reasons why we need to ensure information security. Firstly, if the information system of a company faces cybercrime, it can result in huge losses. For instance, financial loss and loss of reputation.

So the way a company handles an attack will also determine how they recover from the attack.

Therefore, they need to do everything for them to remain successful and competitive in their industry. That is how important our information security is.
