VPN module makes securing remote Scada communication easy
29 July 2009
Byres Security and MTL Instruments have introduced the Tofino Virtual Private Network (VPN) product line as part of the Tofino Industrial Security Solution, extending cyber security beyond plant walls. The Tofino VPN Server LSM (Loadable Security Module), the Tofino VPN Client LSM, and the Tofino VPN Client License are designed specifically to be simple to use and to securely connect facilities and people together over untrusted networks, such as the Internet.
Security for the Tofino VPN is provided by Secure Sockets Layer (SSL). Deployment is completed centrally using the Tofino Central Management Platform (CMP), and does not require any changes to existing control system network design or addressing. The Tofino VPN modules can be operated in “test” mode before they are activated. All of these features make the setup of the Tofino VPN easy, ensuring that neither industrial security nor industrial reliability are compromised by complex configuration errors.The Tofino VPN solution integrates seamlessly with the Tofino Firewall LSM and the Tofino Modbus TCP Enforcer LSM. This close integration makes certain that only “permitted” messages are distributed, and not potentially dangerous transmissions such as a virus originating from a remote PC, or a user sending inappropriate programming commands.
