“…Iaiani et al [29] seem to fall down on the side of letting attacker sophistication guide the definition of security levels by stating "the higher the complexity of the attack and the higher the security level" -but do not attempt to codify this in any way.…”

“…Iaiani et al [29] have developed an operating methodology, PHAROS (Process Hazard Analysis of Remote manipulations through the cOntrol System), to address the identification of major accident scenarios due to remote manipulation of the physical components of the plant (e.g., remotely con-trolled valves, pumps, compressors, etc.). PHAROS employs a reverse-HazOp concept, including specifying barriers aimed at the prevention and mitigation of such scenarios.…”

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.
