CIA Security Model Confidentiality, Integrity & Availability Created by Imran Ahmed (ImranahmedIT) www.imran-ahmed.co.uk Availability Data
What is the CIA Model?  A simple but widely-applicable security model is the CIA triad standing for:  Confidentiality  Integrity  Availability  These are the three key principles which should be guaranteed in any kind of secure system.  This principle is applicable across the whole subject of Security Analysis, from access to a user's internet history to security of encrypted data across the internet.  If any one of the three can be breached it can have serious consequences for the parties concerned.

Confidentiality  Confidentiality is the ability to hide information from those people unauthorised to view it.  It is perhaps the most obvious aspect of the CIA triad when it comes to security; but correspondingly, it is also the one which is attacked most often.  Cryptography and Encryption methods are an example of an attempt to ensure confidentiality of data transferred from one computer to another. Created by Imran Ahmed (ImranahmedIT) www.imran-ahmed.co.uk
Integrity  The ability to ensure that data is an accurate and unchanged representation of the original secure information.  One type of security attack is to intercept some important data and make changes to it before sending it on to the intended receiver. Created by Imran Ahmed (ImranahmedIT) www.imran-ahmed.co.uk
Availability  It is important to ensure that the information concerned is readily accessible to the authorised viewer at all times.  Some types of security attack attempt to deny access to the appropriate user, either for the sake of inconveniencing them, or because there is some secondary effect.  For example, by breaking the web site for a particular search engine, a rival may become more popular.
