Layered Security in Plant Control Environments
Process control vendors are migrating plant control technologies to more open network and operating environments. This White Paper explains how layered security can be accomplished by adopting a "best practices" model, developing and implementing an access control plan, and compartmentalizing the network.
Application of Fingerprints to Increase Security
This 9-page paper summarizes the various applications and benefits of the use of fingerprints to restrict access to information and transactions. It covers access via the Internet and other networks as well as physical access.
