The CIA Triangle
Three Coe
 Confidentiality
 Integrity
 Availability
You can never accomplish one of these objectives
fully without sacrificing the other two to some extent.

Example: If you want the data to be extremely
available then you will have to reduce the
confidentiality because you will have to implement
fewer and easier to bypass security measures. On
the other hand you might have to sacrifice some of
the integrity of the data by allowing more users to
edit the data.

The SFE Triad
Three Coe
 Security Security
Functionality
 Functionality
 Ease of Use
An increase or decrease in any one of the factors
will have an impact on the presence of the other
Ease of Use
two.

Example: By increasing the amount of functionality
in an application will decrease security (increase the
area that a malicious user can attack).
