1 INTRODUCTION This paper explores the state of ne twork security options today at the Ethernet switch level and offers an elementary roadmap for industrial operations to plan for and deploy secure communications systems.
More and more industrial sites are taking advantag e of Ethernet as a mature, end-to-end, standards- based networking, communications and data transmi ssion protocol because it offers convenience and efficiency that bring higher performance and lower cost.
As Ethernet has expanded into outly ing industrial facilities, two types of network structures emerge: Local and Remote. The Local Ethernet structure is within th e walls of a singl e facility which c.
be properly addressed, the benefits of controlling the f unctioning of equipm ent in remote locations such as power substations, and linking outlying facil ities such as aircraft maintenance hubs and other far-flung industrial applications.
(TLS). These features allow an Ethernet switch to handle HyperText Transfer Protocol Secure (HTTPS), the highest level of Web access secu rity available. Other security strategies available to Ethernet eq u ipment include port security, rem ote Telnet access security, password protection and remote unit cut-o ff protection.

APPENDIX A BRIEF OVERVIEW OF SP99 AND PCSRF At the vanguard of developing security guide lines for industrial c ontrol systems are the Instrumentation, Systems, and Automation Society (IS A) and the National Institute of Standards and Technology (NIST).
• security vulnerabilities addre ssed by this technology; • typical deployment; • known issues and weaknesses; • assessment of use in the manufacturing and control system environment.
APPENDIX B SECURITY STANDARDS IN USE IN ETHERNET INS TALLATIONS The protocols and standards listed below are readily available components that can be used to implement secure Ethernet networks in factories, power substations and other industrial sites.
authorized manager, and that the me ssage was not altered in transit. Note that the shared secret key between sending and receiving parties must be prec onfigured by a configurati on manager or a network manager, and loaded into the databases of the various SNMP m anagers and agents.
11 TLS – Transport Layer Security TLS is a successor to SSL, using a wider variety of cryptographic algorithm s for access security. It is standardized by the Internet Engineering Task For ce (IETF). It is a protoc ol that provides secure communication over a TCP/IP connection such as th e Intern et.
