Abstract

Legacy SCADA systems are inherently insecure. They were built using specialized and proprietary protocols and used serial link, radio or leased line for communication. As these protocols were little known and specific to the industry they catered to, security was not important for them. But, recently because of increased terrorist attacks and migration of these protocols to TCP/IP, they have become susceptible to foreign attacks. We propose a mechanism to secure existing and future DNP3 networks. We built a BITW (bump - in - the - wire) prototype which exchanges keys and uses those keys to encrypt the data flowing on the network. We used DNPSec as our framework for BITW.
