Protect Network-Based Power Grid Applications From Denial of Service Attacks

Overview Today distributed industrial networks use Internet to transmit feedback and control signals between a plant and a controller. However there are several attacks on the Internet. From these attacks perhaps Denial-of-Service (DoS) attack is the most detrimental one that affects the packet delivery. DoS attack causes significant disruption to the Internet, which will threaten the operation of network-based control systems. This paper shows how one can protect application sites against DoS attacks via overlay network. This paper designs the Protection Overlay Layer (OPL) such that it makes a secure layer for communication among application sites of power grid in spite of large amount of DoS attacks.
