RTU security enhancements

Semaphore has introduced security enhancements for its T-Box line of SCADA system RTU products. HTTPS and IEEE 802.1X are now available with a T-Box MS Modular System, when equipped with a 32-bit CPU.

HTTPS is the hypertext transfer protocol with encryption using the SSL or TLS protocol. It is now available as an add-on which allows access to the T-Box MS integral web server using HTTPS. Simple menu interactions allow the user to configure the TCP ports for HTTP and HTTPS, whether HTTP is blocked, and to specify a certificate file name.

IEEE 802.1X addresses a key security risk that many operators have uncovered in vulnerability assessments. IEEE 802.1X provides authentication for devices wishing to access a local area network (LAN). Also available as an add-on, it prevents rogue devices from attaching to the LAN or RTU port. That, in turn, prevents unauthorised access to proprietary information and the ability to download configuration or operation parameters.
