ComNet Communication Networks added to its line of intelligent media converters. These intelligent media converters with Link Guardian create a physical layer of protection that limits network traffic to one-way communication between the source and destination networks. The ComNet CNGEUMC4+2(TX, RX)/M is designed to prevent cyber security attacks by limiting data flow to one direction between a secured and unsecured network. How the devices are deployed will determine which direction the data will flow. Called a “unidirectional media converter,” this physical security is more effective than software-enabled network firewalls. This data connection is un-hackable and invulnerable to malware, the company reported. The ComNet CNGEMUMC4+2(TX, RX)/M is a hardened four-port all-gigabit intelligent media converter. This product is designed to provide deterministic data transfer in only one direction to segment and protect networks, devices, and other digital assets (databases, historians, SCADA, PLCs, DCS, etc.) from external cyber threats. It has four 10/100/1000Base-T(X) copper ports and two 1000Base-FX SFP ports. It effectively allows data to travel in only one direction. The CNGEMUMC4+2(TX, RX)/M provides exclusive functionality for easy field deployment including DIP switch-based operation of redundant SFP for creating redundant fiber connections.
