Using threats to demonstrate the elements of information security

The purpose of information security that most infosec specialists identify is to preserve the three elements of confidentiality, integrity, and availability of information. The paper by D. Parker (1991) argues that this is a dangerously oversimplified definition of infosec. The preservation of these three elements does not include many kinds of information losses that infosec should prevent. The author´s intent is to demonstrate in more rigorous fashion that the preservation of these elements must be expanded for infosec to be sufficiently comprehensive to protect information appropriately in all of its security aspects
