Bay Networks has tightened up security for mobile users accessing their corporate networks remotely.
Last week Bay launched BayStream Dial VPN, a service that lets users operate Virtual Private Networks (VPNs) over public telecoms networks.
It is the first implementation of the industry standard Mobile IP protocol.
Mobile IP enables corporates to set up secure tunnels between dial-in users and the network. By extending the private network in this way to allow remote dial-up access, Bay effectively eliminates most of the security concerns that normally dog remote access over public lines.
"Creating an IP tunnel through a network means you are creating a virtual network for each user," explained Trevor Dearing, product marketing manager at Bay UK. "In this way, you don't become a part of the melee on the lines, and your traffic doesn't get confused with other peoples' traffic."
"There's been a lot of talk about tunnelling," he added, "but we're one of the few companies who can deliver, and we're first to market."
BayStream Dial VPN Services will be targeted at large corporates who want to implement it on an enterprise-wide basis. It will also be sold to ISPs and telecoms carriers, who can in turn offer their corporate customers the ability to access their LAN remotely via a dial-up or ISDN connection.
The software also allows security functions such as user authentication and authorisation to be controlled at the customer's end without changes to the firewall or to security policies. Another layer of security comes from Bay's extension of the Mobile IP protocol to support periodic tunnel authentication, ensuring that only authorised devices have access to the gateways.
The software, available now, will only run on Bay Networks' hardware.
It is bundled free with both the BayStream Remote Access Software 4.2 (part of the 5000MSX switching platform), and the BayStream Router Software 7.0. Those products are priced from #363 and #2,167 respectively.
