NEC Develops Secure Remote Access Technology

NEC today announced that it has succeeded in the development of a secure, remote access technology, enabling access to one's office network via a secure virtual link between the internet on a pre-authenticated terminal (PC or mobile phone) and a base station inside the office LAN. The installation doesn't impact the existing network infrastructure since the link can be created without any firewall configuration deployed at DMZ.

The features of this new technology include:

  1. A mechanism for establishing an outbound virtual link, which is created from the base station inside the office LAN and connected to the terminal issuing the access request via an e-mail system over the internet. This mechanism allows establishment of the link without configuring firewalls, intermediate routers or proxies, which are deployed in the office LAN or at DMZ. The base station is deployed at an unreachable IP point, protecting it from hackers.
  2. An Ethernet tunneling mechanism that sends and receives the SSL-encapsulated ethernet frames in the virtual link. This mechanism allows the terminal to access all of the office's LAN applications, including IP and non-IP applications.
  3. An L2 firewall mechanism that blocks all of the incoming and outgoing packets, except those packets being transmitted via the virtual link, on the terminal. This prevents the terminal from being infected by a virus and spreading it to the office LAN, as packets transmitted through the office LAN are usually supported by full virus protection.

NEC's newly developed access technology can be utilized even in divisions and SOHOs without network specialists. NEC's technology can also be applied to remote home access from the Internet.

This technology will be exhibited at C&C user forum & iExpo 2005 being held from December 7-9 at Tokyo Big Site, Japan. It will also be presented and demonstrated at IEEE Consumer Communications and Networking Conference 2006 (IEEE CCNC 2006) being held from January 8 - 10 at Harrah's Las Vegas Hotel & Casino in Las Vegas, U.S.A.
