The Information Security Triad

The information security triad is made up of three elements. But the core of it is confidentiality, integrity, and availability.

It’s a concept that many people do not think about when it comes to information security.


Confidentiality is knowing who has access to what information. You want to make sure that only the people who need to have access to certain information have access to it.

For example, you could have a very sensitive document. So that contains a company’s financials and you don’t want that document floating around your network.

You want that information to be readily available to the right people at the right time.

And so, you need to have good control over who has access to what information at all times. It is because if not, then attackers can get this information and start using it against you.

They could even sell this information on the black market for a lot of money. And so, this is why confidentiality is so important in the IT industry.

There are many hackers out there who are looking for weaknesses in your system or your network. So they can exploit them and steal data from your company.

Also, it could cause other types of damage as well. So that’s why confidentiality is very important when it comes to information security.


Integrity is related closely to confidentiality. It’s making sure that no one tampers with your data or changes your data without authority.

For example, if someone gets into your network and modifies a document. You would want to know about it immediately. It is because it could cost you a lot of money in lost revenue or other damages.

Integrity means making sure that no one tampers with your files. Especially if without authority otherwise known as unauthorized access or modification.

So if someone tampers with your files, then they’re going to change them without authorization. Then what can happen is that they could delete one of those files which could be detrimental to your business.

So you need to know if anyone tampers with your data in any way.


And finally, availability is making sure that your network and all of the system resources are available for users whenever they need them. If you’re having an attack and viruses are running around your network.

Then you can’t access any of your data or any of your systems. Then obviously the attacks are successful in taking down your business or even shutting down your business completely.

So availability is critical when it comes to the Information Security Triad and general.

If you do not have these three elements in place, especially confidentiality and integrity. Then you are prone to attacks. Because there is no security in place to protect your data.

And that’s why it’s important to have these three elements in place when it comes to information security.
