 == Confidentiality
 
-Confidentiality is "the property, that information is not made available or disclosed to unauthorized individuals, entities, or processes." In other words, confidentiality requires that unauthorized users should not be able to access sensitive resources. Confidentiality must be balanced with availability; authorized persons must still be able to access the resources they have been granted permissions for.
