About The Open Group

Entera is secure. Through its support of advanced DCE security, to its extensibility in being able to support any independent GSS API provider, Entera has always had security built-in.

The code generated by NXTera includes the code to initialise the server into the DCE world and to handle and automate all aspects of server security

Modern control systems have evolved to using standard communication protocols implemented over computer networks. Legacy control systems used serial protocols, either over dedicated communication lines for local communications or over dedicated or dial-up lines for long-distance communications. Each of these protocols was developed by one of many vendors for their specific hardware. Over time, the control system industry has consolidated and transformed into fewer vendors who are using fewer protocols that have become either actual or de facto standards. As both the installation and operational costs of dedicated communications has risen, integrators and operators have turned to the ubiquitous information technology communications infrastructure. Protocols have been adapted to use either Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) riding within Internet Protocol (IP) packets over standard IT types of infrastructures. This testing only addressed protocols that use the TCP/IP protocol.
