The proliferation of Industrial Ethernet as the main infrastructure for mission-critical processes is raising concern about the vulnerability of these networks to cyber security threats. Any modern industrial automation network that uses Ethernet-based infrastructure needs to implement proper security measures. Due to the unique characteristics of industrial applications, existing security concepts from the enterprise world do not necessarily apply; and new security concepts for industrial control systems need to be defined and implemented. In this context, service-aware switches are the basis for an optimized network.
This paper compares common security models with distributed service-aware security, and reviews RADiFlow’s defense-in-depth tool set.
