Confidentiality
Confidentiality means privacy, to protect your information. Of course we do not want external or unauthorized people or entities to have access to our precious and valuable information.

And that is just one example.
How can we protect? ENCRYPTION! I will discuss that subject in another post.
Integrity
Access to information is an issue, but what can be worse than that? Imagine unauthorized people accessing your information and MODIFYING IT! There are some measurements that data itself has to check the integrity, as checksums. This is just to protect information from being consistent and accurate.

Availability
Availability, in the contrary is to make sure that anyone authorized, can access to the information whenever they need. Information is as precious and valuable from us as it is for other people. Imagine that all of a
