Data transmission is utilised and plays an extremely important role in OT system networks. System equipment such as servers, computers, firewalls, routers, switches, storage, modems, gateways, SCADA (Supervisory Control and Data Acquisition), PLCs (Programmable Logic Controller), PACs (Programmable Automation Controller), DDC (Direct Digital Control) and field plant, assets, equipment and devices transmit data via serial ports such as RS-232 and RS-485, Copper twisted pair, Coaxial, Ethernet, Fibre and Wireless networks.
We design and supply OT systems that can identify and authenticate all devices within the system to mitigate the risk of untrusted devices on a network that has the intention of taking control of a network along with closing the separation between IT and OT.
Our solutions consider the physical and software configuration to make sure data generated from systems has integrity and accuracy for the use of smart analytics.
We have extensive experience with integrating and mapping dissimilar network, file and protocol types into unified systems that verify devices are reliably communicating and correctly.
With the greater threat of cyber-attack, it is essential that systems and plants are secure. We are familiar with the use of segregation, encapsulation, and DMZs (Demilitarised Zones) to enhance security. With the use of VPNs (Virtual Private Networks), VLANs (Virtual LANs), Firewalls, Proxy Servers, and Domain Controllers.
