Tokyo, December 02, 2005 --- NEC Corporation today announced
that it has succeeded in the development of secure, remote access
technology, enabling easy and instant 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. Easy installation and use without any impact
on existing network infrastructure is realized as the link can be
created without any firewall configuration deployed at DMZ (note
1*).
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 easy establishment
of the link without the complicated configuration of 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 cyber 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.
Recently, along with the spread of broadband access,
internet-utilizing remote access systems are drawing great
attention as a method for enhancing office productivity through the
sharing of IT and network resources. However, although current
remote access technologies are being widely used, there were still
issues that needed to be solved to realize easy to manage and use
secure, remote access systems, including:
(1) High cost: resulting from configuration changes of network
devices at DMZ and in the office LAN.
(2) Security: protection of the remote access gateways from
cyber hackers.
(3) Usage restriction: of LAN applications caused by sole
dependence on IP protocols at the remote access gateway.
(4) Virus infection and information leakage: caused by direct
access to the Internet from the terminal.
NEC’s newly developed secure, remote access technology has
succeeded in solving these issues, enabling easy establishment of a
secure virtual link. This breakthrough will enable remote access to
be utilized even in divisions and SOHOs (note 2*) without network
specialists, which are normally vital to installation and
maintenance of a complex system. 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 (note 3*) being held from Dec. 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 .
