PacketGuard Security for ModBusTCP Industrial Networks
http://www.moxa.com/Event/Net/2013/Gi...
PacketGuard™ is the world's first built-in Modbus TCP packet inspector. With PacketGuard, the EDR-810 will inspect network packets all the way up to the Modbus application level, deeper than the transport-layer scanning that conventional network firewalls can achieve.
The EDR-810 is the latest in Moxa's EDR family of network security devices tailored for industrial operators. It combines security, routing, and layer 2 switch functionality into a single device, making it a highly convenient and cost-effective solution that connects and protects many devices.
