Context-based security (and Safety) meta-policies for pervasive computing environments: The case of smart homes
Pruthvi Shetty, Seng W. Loke · Own your potential (DEAKIN) · 2005
Context-based security is an approach for modeling adaptive security solutions based on the situation of use of the system. Security policies in this approach are not static as it used to be in traditional systems. The security actions to be taken are based on the knowledge of the combination of various factors such as the location of the user, the surroundings, time, temperature etc making the security policies more adaptive. The aim of this paper is to present security meta-policies based on an existing approach known as Contextual Graphs and the multilevel access model, which we presented in our previous paper. These meta-policies determine within what contexts actions in other policies should be taken – it is in this sense that we have the notion of other policies “embedded” within the meta-policy. Our approach can be easily used in various smart environments, even for context-aware safety meta-policies. The paper presents their use in a smart home scenario.
