1 INTRODUCTION This paper explores the state of network security options today at the Ethernet switch level and offers an elementary roadmap for industrial operations to plan for and deploy secure communications systems. Industrial systems need to take advantage of the advanced networking technologi...

More and more industrial sites are taking advantage of Ethernet as a mature, end-to-end, standards- based networking, communications and data transmission protocol because it offers convenience and efficiency that bring higher performance and lower cost. In addition, the standards that are in place ...

Web access provides very significant efficiency improvements a...

Other security strategies available to Ethernet equipment include port security, remote Telnet access security, password protection and remote unit...

APPENDIX A BRIEF OVERVIEW OF SP99 AND PCSRF At the vanguard of developing security guidelines for industrial control systems are the Instrumentation, Systems, and Automation Society (ISA) and the National Institute of Standards and Technology (NIST). ISA, through its SP99 committee, has published tw...
