Cyber security

Abstract

Many incidents in the last years, and their increasing prevalence and damage, showed that cyber security is important. One big problem, which is expected to increase even more in the future, is the large-scale deployment of devices with very little security or a wide default security configuration. Automatization of such configuration is therefore necessary. This paper proposes a security model based on the household metaphor, where every device is assigned a role similar to a person in a household. Default permissions are then assigned to these roles by the manufacturer. In this way configuration of new devices is reduced to assigning it an "owner" it may represent towards other devices. While this is definitely not high security, it allows introducing some restrictions to an area where currently the options are either no security at all, or extensive and complicated manual configuration of each element, which is additionally difficult to understand for end-users.
