Introduction to Continuous Authentication
Issa Traoré, Ahmed Awad E. Ahmed · IGI Global eBooks · 2011
Continuous Authentication (CA) systems represent a new generation of security mechanisms that continuously monitor user behavior and use this as basis to re-authenticate periodically throughout a login session. CA has been around for about a decade. As a result a limited amount of research work has been produced to date, and the first commercial products have only recently started reaching the market. We attempt, in this chapter, to provide some general perspectives in order to help achieve some common and better understanding of this emerging field. The chapter introduces basic CA concepts and terminologies, discusses the characteristics of CA data sources, and identifies major areas of application for CA systems.
