Fast, high quality service for machinery and production equipment installed worldwide would be inconceivable without remote tele-maintenance service. Service costs are significantly reduced, particularly during the warranty period. In the past, two hurdles existed: security concerns regarding unauthorized operators dialing into the network, and problems with antiquated modem connection technology. The Internet and VPN-based connections are increasingly replacing dial-up modems, and new industrial network security modules are providing tailored solutions efficiently and economically.

The key developers at Innominate Security Technologies decided to devise an innovative concept—providing IPsec VPN connections from the systems to the service center. This technical paper details Innominate’s technical security solutions, along with four examples from industry.
