USERS AWASH IN EMERGING WIRELESS OPTIONS

a complex landscape of overlapping choices. There are decisions
to be made regarding devices, carrier contracts, performance and
reach. How do you know which decisions are the right ones? Click

Today's focus: Blue Ridge Border Guard blocks sudden security
breaches

By Tim Greene

Blue Ridge Networks is introducing a security appliance family
that has built-in digital certificates and can override them on
the fly to block sudden security breaches.

Called Border Guard 6000, the devices can red list users,
cutting them off the VPN even if they have a valid digital
certificate. The certificate itself stays valid, so if security
administrators decide access should be restored, it doesn't
require fiddling with the certificates themselves.

This feature is designed for protecting very sensitive data. It
lets network security staff cut off a user's access immediately
without having to revoke certificates and wait for any current
sessions to end before the cutoff takes effect. If a user's
behavior on the network is suspicious or malicious, access can
be cut right away. Similarly, if the user is fired suddenly,
their access can be terminated.

By containing its own digital certificates, the devices make
setting up two-factor VPN authentication simpler because no
external certificate authority is needed. But if a business
already has an established public key infrastructure (PKI), the
appliances can tap into that as well.

This is important to businesses and government agencies that
have invested in, say, VeriSign or Entrust for PKI already and
don't want to complicate it by having their VPN gear use a
separate infrastructure.

The new appliances have a tunnel-lock feature that allows only
traffic in and out of remote machines via the VPN during VPN
sessions, protecting the VPN from attempts to hack in from
devices that are on the same LAN with the remote computers. The
Border Guard 6000 family supports roaming with a wireless
laptop, so if a machine is connected to a VPN and the user
wanders from access point to access point, the session stays
alive.

Border Guard 6000 series gateways come in five models - 6100,
6200, 6400, 6500 and 6600 - and cost $4,000 to $20,000. They
differ in VPN throughput and number of concurrent users
supported.
