Mobility and Spatio-Temporal Exposure Control: Exposure Control as a Primary Security and Privacy Tool Regarding Mobility, Roaming Privacy and Home Control

Modern risk assessment methods cover many issues and encompass both risk analysis and corresponding prevention/mitigation measures. However, there is still room for improvement and one aspect that may benefit from more work is “exposure control”. The “exposure” an asset experiences plays an important part in the risks facing the asset. Amongst the aspects that all too regularly get exposed is user identities and user location information, and in a context with mobile subscriber and mobility in the service hosting (VM migration/mobility) the problems associated with lost identity/location privacy becomes urgent. In this paper we look at “exposure control” as a way for analyzing and protecting user identity and user location data.
