What is CIA Triad?
The CIA Triad is a security model which helps to keep an organization secure. There are three parts to it – Confidentiality, Integrity, and Availability. And it is about the data.
Confidentiality – only authorized resources can access the data.
Integrity – data is consistent, accurate, and trustworthy during its lifecycle. Only authorized resources can change the data.
Availability – ensures that data can be stored, accessed, and protected at all the time.
Take down any of these components and your security is pretty much compromised.
Let’s use as an example your bank. By having confidentiality you are assured that only authorized personnel, and probably you as well can see your account statement. Integrity means you can’t change your balance to something which you would prefer to see there, nor somebody else can’t do this without authorization. Availability is when you can access your account balance at any time and you can do your payments when needed.
