Cisco
Products Enable a Secure VPN
A wide variety of Cisco products actively support VPN
connections throughout the network. Cisco’s Unified Client Framework strategy
enables all adhering VPN client technologies to connect to any Cisco
central-site VPN concentrators, including the Cisco 3000 series VPN
concentrators, PIX Firewalls, and Cisco IOS-based routers.
The Cisco VPN software client is typically provided at no charge
with central site concentrators, so the software client is inexpensive to deploy
and scale to large numbers. These VPN clients have specific limited operating
system (OS) support and might require some level of support. These software
clients could be impractical in those extranet environments where the
organization doesn’t own or control the remote PC, such as in a franchise or
customer location. The organization might not want to absorb the expense
associated with maintaining and supporting non-company workstations.
Cisco small router and firewall devices can be an inexpensive way
to provide security features like stateful firewall and VPN capabilities to
remote sites. Unfortunately, these devices don’t scale beyond a few hundred
devices. Deployment, monitoring, and ongoing support can be inconvenient,
time-consuming, and expensive because of the variety of features and options
that must often be manually configured at both ends of the connection.
The Cisco VPN 3000 Series Concentrator, combined with the Cisco
VPN 3002 Hardware Client device, scales to support customers with 100 or fewer
remote access users to large organizations with up to 10,000 simultaneous
connections. The Cisco VPN 3000 Series Concentrator is available in both
nonredundant and redundant configurations, providing the customer with multiple
options to design and build robust, reliable, and cost-effective networks.
What’s New?
The latest Cisco VPN 3000 Series Concentrator OS, release
3.6, is the most recent version at press time. This release includes simplified
VPN Software Client—Easy VPN— which allows minimal client configuration and
“push” technology to download the configuration from the concentrator.
Additional release 3.6 features include AES support, expanded support for
Microsoft’s Integrated VPN Client in Windows 2000/XP, and security for wireless
environments.
The new Cisco VPN 3002 Hardware Client, covered in the next section,
combines easy implementation and rollout, plus high scalability, with the
performance, reliability, and stability of a hardware device.
The Cisco VPN 3000 Series Concentrator Wireless Client Support for
Elliptic Curve Cryptography (ECC) provides faster information processing by
personal digital assistants (PDAs) and smart phones.
The Cisco VPN 3000 Series Concentrator, Cisco VPN 3002
Hardware Client, and the Cisco VPN Client work together with the Cisco Internet
Mobile Office to provide mobile professionals with secure, high-speed broadband
connectivity to their networks in airports, convention centers, hotels, and a
growing number of other public spaces.
