Intelligent Network Layer for Cyber-Physical Systems Security

The cyber-physical system (CPS) has made tremendous progress in recent years and also disrupting technical fields ranging from health, transportation, industries, and more. However, CPS security is still one of the concerns for wide adoption owing to the high number of devices connecting to the internet and the traditional security solutions may not be suitable to protect the advanced, application-specific attacks. This paper presents a programmable device network layer architecture to combat attacks and efficient network monitoring in heterogeneous environment CPS applications. The authors leverage industrial control systems (ICS) to discuss the existing issues, highlighting the importance of advanced network layers for CPS. The programmable data plane language (P4) is introduced to detect well known HELLO flood attacks with minimal effort in the network level and show that programmable switches are suitable to implement security solutions in CPS applications.
