The concept of barriers is well known in the safety domain that includes traditional process control environments. However, as critical infrastructures are moving to more interconnected scenarios connected to cloud computing service providers and the internet in general, an increased focus on security is necessary. In this paper we present a survey on how cybersecurity barriers have been presented in the literature, concluding that the concept has received little attention. More specifically, the aim of the paper is to survey the state of the art in cybersecurity barrier management and the integration with safety barrier management. Like the concept of cybersecurity barrier, the integration of safety and cybersecurity barrier management has received little attention. Most of the work focus on integration of safety and cybersecurity management in general, not on barrier management specifically. We eventually aim to integrate cybersecurity barrier management into the already existing safety barrier management regime.
