  Cyber-Physical System (CPS) has made a tremendous progress in recent years
and also disrupted many technical fields such as smart industries, smart
health, smart transportation etc. to flourish the nations economy. However, CPS
Security is still one of the concerns for wide adoption owing to 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. We leverage Industrial control systems (ICS) to discuss the
existing issues, highlighting the importance of advanced network layer for CPS.
The programmable data plane language (P4) is introduced to detect well known
HELLO Flood attack with minimal efforts in the network level and also used to
featuring the potential solutions for security.
