In today's Industrial Control Systems (ICSs) interconnection and reliable communication are valuable properties that enable the controlling and monitoring of various processes-even remotely. Cyber attacks or attacks via local digital interfaces break security requirements by altering software, configurations or control sequences. In such cases, safety requirements can no longer be guaranteed. Further,...
The expansion of Ethernet in service provider domain requires modification of its service models and management issues. Works are underway inside research community, but their main focuses on Quality of Service, failure recovery, scalability, reliable connectivity, resource utilization and traffic monitoring put security in isolation. As developed initially for a shared link communication, Ethernet...
Media Access Control Security (MACsec) is a new segment based link layer security, which is standardized on 2006. It leaves data in clear inside switches and facilitates packet inspection at those connection points. The support for traffic analysis is crucial for Enterprises or Service Providers in secure premises, but when the networking devices are placed in populated areas (e.g., hospitals, airports),...
Considering the dominance of Ethernet with upcoming 100 Gbps line rate, service providers want to reduce their transport networks to simpler Layer-2 networks. Since existing Ethernet security mechanisms protect links in hop-by-hop basis, they cannot control access for disloyal authorized users in virtual or logical shared media infrastructure LANs. Also they leave data in clear inside intermediate...
