ABSTRACT

The increasing frequency and malevolence of online security threats require that we consider new approaches to this problem. The existing literature focuses on the Web security problem from the server-side perspective. In contrast, we explore it from the client-side, considering the major types of threats. After a short threat summary, we discuss related research and existing countermeasures. We then examine intuitive human-oriented trust models and posit a flexible, multilayer framework to facilitate automated client-side decision making. The proposed suggestions are not intrusive and do not require advanced technical knowledge from end users. Copyright © 2011 John Wiley & Sons, Ltd.
